Thank you so much for this laemens terms instruction on mixing this fuel! My father died April 1st and we relied on his expertise for all of these jobs. But I'm trying to carry on his legacy as his 36yr old daughter by not being afraid to role up my sleeves and figure out how to accomplish his work.

I ran out of gas mid-trip and had no choice but to mix in the tank. Bought a 2.5 oz. bottle of 2-cycle oil from O'Reilly's, then walked the bike to Walmart to get gas. Took a guess and put 1/2 gallon in the tank, then ran the calculator for 20:1 per "conventional wisdom" and found out according the calculator I was supposed to add 3.2 ounces, but I only had 2.5. Thought "fuck it, I won't kill the engine for a short 2 mile trip to home", mixed it in the tank (knew that was wrong but I had no choice). First thing I noticed is loss of power. Assumed the fuel/oil ratio in the gas might be in some kind of conflict with the fuel/air ratio set at the carb, but I made it home ok, just a bit underpowered. (Like 10% or so. not 50% low power.) Anyways now I'm doing research on pretty much everything. First thing to the channel owner, that graphic about not using Marine oil was really useful, because I almost bought Marine oil at O'Reilly's thinking they were probably the same, and that the price difference was just a scam/marketing. So, this information was useful to me. Thanks. Second, a comment below about lower-octane fuel actually being higher in power/energy content explains the lower power. Does it? What about my oil/fuel, fuel/air "conflict" theory? Did running higher ratio fuel/oil make my carburetor's output to the engine less efficient? I'm going to take the video's advice and raise the fuel/oil ration to something greater than 20:1. Not sure if I have the courage or the faith to go all the way to 40:1, but I figure if 20:1 is bad, and 40:1 is good, then 30:1 is better than 20:1. Point here is that whatever mix I do, I'll be adjusting the carb for power. Just curious if this makes sense to people. Seems to me that the set-screw at the carb is too rich (counter-clockwise, and please correct me if I'm wrong). But when I lean it, the engine has a "stopped" effect when running. The engine sounds weird, the power diminishes. I can't describe the sound, but it's not "pure" and "clean". What's the word for this?
I live in South Africa, I’m using 25ml to 1 litre. I was using around 35ml before and oil was spluttering out everywhere. Now it’s perfect. Also, as you said, I’m going to keep at 25ml mix, till it’s eventual death 😛
I bought a gallon gas tank and I buy the 1 gallon 40:1 mixers at Walmart for 98 cent's a bottle takes the guess work out super cheap got 750 miles on it now just took the top end apart very little carbon build up using cheap non synthetic oil oh and she does 35 mph

Thank, you explained, cool. From panama city my son & me see your great videos, thanks, joe.
I have been running 24 to one. I will try 30 to 1, but I'm afraid to use less oil. I really don't want my customers to blow up their engines. Thanks for your advice.
Expensive stuff, I’ll tell ya as a Stihl repairman that 40:1 is probably best. These are higher-revving cheap engines that don’t need you to spend $25 a gallon on. 40:1 will give you the peace of mind of everything being lubed up and running correctly. The next thing is ethanol... is it better to run ethanol free? YES! is this an expensive engine? NO! Personally I ride my bike every other day, so regular 93 octane, 10% ethanol- mixed with conventional two stroke oil isn’t gonna kill it. If I let the carb sit with it in there all winter long- you betcha! Pick and choose battles my friend. Happy riding!
I still have my high school 80cc board track racer beach cruiser bike she has around 18,000 miles on her all I’ve had to fix her a few times the clutch and the piston bearing. I’m planning on replacing the rings tomorrow thou she’s making a weird grinding sound when going down the high way at the moment
40:1 is 125ml per 5 litters. Just ask for 5 liters when you take your Jerry can to the gas station to fill it. Messing around trying to properly guage the off numbers from filling a partial tank at the gas station will be dodgy to get right unless you are a whizz at math. And going off your gut instinct and guestimating is rarely going to provide an accurate mixing. Also it's better to shake the gas and oil together and not just hope that it mixed well without shaking the both together first. And is easier to do in a Jerry can rather than jerking the bike about. This 40:1 ratio is used for 2stroke bicycle kits, at least mine is anyway.
Im the only one at work who mixes all my gas at 40:1 for our chainsaws . everyone else likes 50:1 in about 18 years of running 40:1 ive never had a saw engine die prematurely.....
I'm actually going to run 100:1 with my access of opiti 2 oil packets, so probably will use the for my premixed gasoline but I did start with 40:1 due to me learning from my past mistakes.
@@sapotts1387 tested it and didn't work, mostly due to engine hating less than 40:1. I did revert back and I'm actually happy with it but now the chain tensioner is bending into the wheel. Be mindful I'm using a Schwinn OCC Stingray chopper bike, I'll need to figure out on what I need.
hi man, little late to the party but i recently bought an 80cc kit, i'm using 35:1 and it works good. But i wanted to ask, does letting out the gas while still at speed and engine braking cause damage to the engine? Should i use the clutch instead?
I ran the fancy sh*t for a while and it definitely smells better and makes less smoke, and the particular brand I was using came in a bottle that made it easy to decant. I dunno that makes it worth it though.
These are great and informative videos. However would like to see some more 4 stroke videos. I thought you had done a video on replacing bearings on a heushang 4 stroke engine or something like that. Now i dont seem to be able to find it. Any help would be greatly appreciated.
I took my pk80 apart before I used it and I thought it was notable that there was very little assembly lube in the top end. I wonder if the 16 to 1 break in ratio is to offset that?
My brand NEW engine sure won't be running on any 40:1 mixture initially. Note the word "new". It's not so much the rings, there's dry bearings in there, connecting rod, etc... stuff that needs lubrication right from the start. Not all of the oil burns off (or turns to carbon), residual oil remains unburnt and that's what lubricates the internals, not just the rings, but the entire inside of the engine. The manufacturer makes recommendations for a reason. 🤔
The guys who build $1000 race engines? They also say use 40:1 from day one. $700 Chainsaws run 50:1 using no break in mix. The "manufacturers" of these engines? They don't know BS about these engines. They buy parts from whatever supplier has the cheapest price and they use unskilled laborers to slam the kits together.
Hey Hughes, not sure if you have but can you do a video on rear tires? More specifically 26x2.125 and compatable tires for cruiser bikes that last longer than stock. Thanks
@Jacob surrett lace a ryno light double wall 36 hole with Dt comp spokes and you can run maxis hookworms or holly rollers up to 26X2.50 you won't regret it. I regret buying mag wheels their junk especially if running rear disc.
I run a 16:1 ratio all the time in my phantom 85. I had an LD 100 before that and I put over 6,000 mi on it running 16 to 1. The motor is still good with no abrasions on the cylinder walls or piston. I've worked on other people's bikes that followed this guy's instruction and used 40:1. And their engines lasted only a couple of months. Less oil means less life. This guy that made this video is just expressing his opinions. His opinions are wrong.
Great video as always..... how can I contact you...???? I would like to show you my project and have you go thru it..... I can certainly use your experience and advice.... this is my second build and I’m running into some issues in adjusting the carb
Yes. 2 strokes need oil in the gas to lubricate the engine or have an injection system that injects the oil into the carburetor. 4 strokes need oil in the crankcase to lubricate and protect the engine
Cant find my answer anywhere....! DO I NEED TO ADJUST MY FUEL RATIO FOR HIGHER ALTITUDES? Obviously I adjust my carburetor for higher altitude but SHOULD I CONSIDER A FUEL RATIO ADJUSTMENT?!?(my motor calls for 25:1 from factory for its life)
@@HughesMotorized Running a Chung Yang GP460 on a Goped TrailRipper; not exactly the same application as you are used to. Factory calls for 25:1 which i blend very precisely but have fouled two spark plugs. trying to figure out the science behind changing the fuel mixture for altitudes.
I`m curious about a cpl. questions, just put in my 66cc grubee , I`m running 35 to 1 (just how it came out) took it for a 45 min. ride lots of variable throttle, tightened the head and away I go .Was wondering about a good idle speed and if 35 to one can go to 40 to 1 next tank. thanks
I am posting this because none of these videos comment sections have it. for a 16:1 ratio 16 parts gas to 1 liter you need to add 8 ozs of oil to a gallon of gas. 4 liters make one gallon. so if you just have a liter. then you add 2 ozs to a 1 liter. ffs
@@Konstantinosmo These are very simple, poorly built motors. No need to baby unless you have a very high performance engine. Simply run them till they die & rebuild
I disagree. If you're building an engine for racing and high-end speed then you do want a lean oil mixture. I'm using my bike for a daily commuter. I need it to be reliable everyday. I need it to last long. I run 16 to 1 in my phantom 85. I ran 16 to 1 in my ld100 and wrote it for 2 years every day. I know a few people that run leaner mixtures. Their bikes didn't last as long. I don't care about performance when I'm trying to get from point a to point b. And my spark plug was completely filled with carbon to wear there was no Gap left and it still kept going. I can send you a picture of it if you don't believe me. Carving is not a conductive material therefore it doesn't file plugs as much as you think.
I am a motorcycle technician sir. 22 years in the business. I am factory certified in Polaris and Can-Am. I'm not here to argue with you dude. But if you want to compare knowledge I can send you a link to a video that proves with results from testing oil ratios.
Ok so I have an 80cc n the dudes been running it on 50:1 n ik that aint right my bike will start n ride for a couple seconds itll jerk like its tryna go n die out so what mixture is best for an 80cc!?!?!
Hello Eugene! I have a question. I use 40/1 (about that. Maybe a little richer) in my new motorized bike. Taking it easy and you know. Basic break in procedure. I use the “synthetic blend”.. is that ok? Everyone on the forum is telling me “40/1 but no synthetic” “30,20,10-1”. It’s driving me nuts. Is 40-1 synthetic ok for a break in? Thanks so much I hope you respond...
helloI got a brand new engine, that rode it 24 miles and it started leaking oil from the side of the head. Do you know what's wrong? Hughes don't know if it needs to be ridden a lot more to ride it normal.
Elevation will affect air density and will affect air/fuel ratio. The fix is to run a leaner jet. Gas/oil ratio should stay the same is my understanding.
these motors are cheap. best oil is formulated for air cooled engines. marine 2 strokers are water cooled. Not the end of the world. I'd offer you swap over or even blend the 2 together to use it up
@@HughesMotorized , I must disagree on this one. Anything designated as Marine use is heavy duty. If in the product description it says Marine Use or Gov-Spc that is the best on the shelf. A two cycle engine is two cycle. In a marine engine, the oil in the gas has the same purpose. With out it the piston is going to sieze. There are no water jackets or waterways in a typical two cycle. They are air cooled. Water does not make its way up top to the Jug.
@@glennspears839 A boat motor will never get as hot as even a water-cooled dirt bike 2-stroke engine during normal operation because of WHAT?. A boat motor is WATER COOLED. The heat generated in a 2 STROKE bike's engine will cook the marine oil. Not good. . Keep the marine oil in your boat and PWC's.
Question, my gas scooter calls for 25:1, i believe that would be the break in period. After I can go 32:1 or 40:1. Now if I switch to 32:1 or 40:1 do I have to manually adjust the carburetor idle and fuel mix screws? If I wanted to do a weeks test for each mix and check the plugs for fouling, and do comparisons on temperatures with different fuel mix, isn't it important to adjust the carburetor each time to the correct fuel mix after it warms up??
These are cheap, poorly built engines. Build a $10,000 engine and then worry about it. Really, you can run used motor oil in these. Ethanol will not hurt these. People even ran used auto oil in 2 stroke motorcycles for years no issues. Don't overthink it
@@HughesMotorized ethanol is damaging all kinds of engines !!! The china doll moter works better at octane level 91 & no ethanol so im trying aspen 50 to 1 premix to see if my moter likes it & if not i will just carry on putting petrol with 5 percent ethanol that is damegingall kinds of two strokes mainly garden tools etc due to ethanol !!!

These are higher-revving cheap engines that don’t need you to spend $25 a gallon on. 40:1 will give you the peace of mind of everything being lubed up and running correctly. The next thing is ethanol... is it better to run ethanol free? YES! is this an expensive engine? NO! Personally I ride my bike every other day, so regular 93 octane, 10% ethanol- mixed with conventional two stroke oil isn’t gonna kill it. If I let the carb sit with it in there all winter long- you betcha! Pick and choose battles my friend. Happy riding!
I still have my high school 80cc board track racer beach cruiser bike she has around 18,000 miles on her all I’ve had to fix her a few times the clutch and the piston bearing. I’m planning on replacing the rings tomorrow thou she’s making a weird grinding sound when going down the high way at the moment
Will you use that on a on a run fast own a yd 100cc bored 50 over how would you mix that gas with a power band
40:1 is 125ml per 5 litters. Just ask for 5 liters when you take your Jerry can to the gas station to fill it. Messing around trying to properly guage the off numbers from filling a partial tank at the gas station will be dodgy to get right unless you are a whizz at math. And going off your gut instinct and guestimating is rarely going to provide an accurate mixing. Also it's better to shake the gas and oil together and not just hope that it mixed well without shaking the both together first. And is easier to do in a Jerry can rather than jerking the bike about. This 40:1 ratio is used for 2stroke bicycle kits, at least mine is anyway.
Im the only one at work who mixes all my gas at 40:1 for our chainsaws . everyone else likes 50:1 in about 18 years of running 40:1 ive never had a saw engine die prematurely.....
I use outboard oil...smokes less and it does say it’s great for air cooled engines...yippee!!!
Some are formulated for air cooled and some are not. I'd want to insure I have one best suited. many run it so ride on !
i persronally use 20:1 even after breaking in, otherwise i get crappy performance
I would love to show you a picture of the the oil can that I've used it's a two-cycle I think 8 oz and I poured it until it went a little bit under 4

I'm actually going to run 100:1 with my access of opiti 2 oil packets, so probably will use the for my premixed gasoline but I did start with 40:1 due to me learning from my past mistakes.
100:1?? Your gonna blow your engine with that little bit of oil.
@@sapotts1387 tested it and didn't work, mostly due to engine hating less than 40:1. I did revert back and I'm actually happy with it but now the chain tensioner is bending into the wheel. Be mindful I'm using a Schwinn OCC Stingray chopper bike, I'll need to figure out on what I need.
hi man, little late to the party but i recently bought an 80cc kit, i'm using 35:1 and it works good. But i wanted to ask, does letting out the gas while still at speed and engine braking cause damage to the engine? Should i use the clutch instead?
I ran the fancy sh*t for a while and it definitely smells better and makes less smoke, and the particular brand I was using came in a bottle that made it easy to decant. I dunno that makes it worth it though.
These are great and informative videos. However would like to see some more 4 stroke videos. I thought you had done a video on replacing bearings on a heushang 4 stroke engine or something like that. Now i dont seem to be able to find it. Any help would be greatly appreciated.
Great point! Some are in the works. I'm doing a 20" Schwinn w/ a banana seat and a 49cc 4 stroke. Stay tuned
I took my pk80 apart before I used it and I thought it was notable that there was very little assembly lube in the top end. I wonder if the 16 to 1 break in ratio is to offset that?
once you start the bike the engine will be instantly sprayed with oil/fuel inside. Zero wear in starting it
Whats the fuel consumption on the road per liter
I wonder if gas with ethanol makes a difference?
My brand NEW engine sure won't be running on any 40:1 mixture initially. Note the word "new". It's not so much the rings, there's dry bearings in there, connecting rod, etc... stuff that needs lubrication right from the start. Not all of the oil burns off (or turns to carbon), residual oil remains unburnt and that's what lubricates the internals, not just the rings, but the entire inside of the engine. The manufacturer makes recommendations for a reason. 🤔
The guys who build $1000 race engines? They also say use 40:1 from day one. $700 Chainsaws run 50:1 using no break in mix. The "manufacturers" of these engines? They don't know BS about these engines. They buy parts from whatever supplier has the cheapest price and they use unskilled laborers to slam the kits together.
Thank you man.. Sharing this.
Glad it helped
Hey Hughes, not sure if you have but can you do a video on rear tires? More specifically 26x2.125 and compatable tires for cruiser bikes that last longer than stock. Thanks
@Jacob surrett lace a ryno light double wall 36 hole with Dt comp spokes and you can run maxis hookworms or holly rollers up to 26X2.50 you won't regret it. I regret buying mag wheels their junk especially if running rear disc.
All 2 stroke oil, whether synthetic, mineral or organic (Castrol R & R40), is rated as SAE 30.
On a run fast 100 cc bored 50 over how would you mix a gas in that the same way with a power band
40:1 no difference
On a run fast 100 cc bored 50 over how would you mix a gas in that the same way
yes indeed. 40:1 3.2 oz oil to 1 gallon of gas or 25ml per liter of gas
Actually 25:1 is what I've found to be the best ratio for engine wristpin and bearing longevity.. If your using regular 2stroke oil
yeah, I have heard between 25:1 and 32:1 is the best.
I run a 16:1 ratio all the time in my phantom 85. I had an LD 100 before that and I put over 6,000 mi on it running 16 to 1. The motor is still good with no abrasions on the cylinder walls or piston. I've worked on other people's bikes that followed this guy's instruction and used 40:1. And their engines lasted only a couple of months. Less oil means less life. This guy that made this video is just expressing his opinions. His opinions are wrong.
I don't like thinkin'...especially in the summer...1cup from my wife's pyrex measuring cup into 2 gallons makes sense to me
8oz oil to 2 gallons? Perfect
I'm confused about oil gas mix after seeing this video I understand
Does it matter what type of gas in a motorized bike engine like it's it ok to use 93 on the bike?
87 is all I run in my bike(stock) but if you get the high compression head then use 89 or 93 so it won't detnate!
ay brother how do you fix if you put the wrong fuel in and it cuts out starting it any solution?
in my location my altitude is 633′ what setting does my jet needle on my nt carb need to be set on on my 100cc 2 stroke
I use 2T but in the city where I live the climate is extremely hot 365 days a year, what oil would you recommend or what measure per liter...
40:1 and any 2 stroke oil
So use 3.2OZ of oil in a 2 gallon Gas can?
Yes indeed
Is tru fuel safe or good
For first 500km the same 40ml with 1l?
40:1 all the time. Forever

Great video as always..... how can I contact you...???? I would like to show you my project and have you go thru it..... I can certainly use your experience and advice.... this is my second build and I’m running into some issues in adjusting the carb
hughesmotorized.com/contact/ contact page
Can i buy the premixed fuel of like amazon or is that a waste.
Waste.
do all motorized bikes need oil
Yes. 2 strokes need oil in the gas to lubricate the engine or have an injection system that injects the oil into the carburetor. 4 strokes need oil in the crankcase to lubricate and protect the engine
semi senthetic?...or it doesnt really matter...as long as it's mixed well with the gas?
Either or. Mix well you good
Helped me out.👌
Glad to hear!
Can I convert my 2 stroke to a four stroke without totally switching out the hardware
no,it's impossible
25ml in 1 liter? Is that okey on china 2 stroke china engine?
yessir. 25ml per liter = 40:1
Do you think 38:1(3.4oz) would be fine just to be a little safe
easy, sure. no prob
I put good oil and high test just so it runs better...I ride mine hard
Cant find my answer anywhere....!
DO I NEED TO ADJUST MY FUEL RATIO FOR HIGHER ALTITUDES?
Obviously I adjust my carburetor for higher altitude but SHOULD I CONSIDER A FUEL RATIO ADJUSTMENT?!?(my motor calls for 25:1 from factory for its life)
On the 66/80cc just run 40:1. Promise it will be fine
@@HughesMotorized Running a Chung Yang GP460 on a Goped TrailRipper; not exactly the same application as you are used to. Factory calls for 25:1 which i blend very precisely but have fouled two spark plugs. trying to figure out the science behind changing the fuel mixture for altitudes.
I`m curious about a cpl. questions, just put in my 66cc grubee , I`m running 35 to 1 (just how it came out) took it for a 45 min. ride lots of variable throttle, tightened the head and away I go .Was wondering about a good idle speed and if 35 to one can go to 40 to 1 next tank. thanks
You can run 50:1 from the first. No issues. Honest. You don't have to slowly change it. Hve fun and watch for cars

@@HughesMotorized youre a fuckin g
I am posting this because none of these videos comment sections have it. for a 16:1 ratio 16 parts gas to 1 liter you need to add 8 ozs of oil to a gallon of gas. 4 liters make one gallon. so if you just have a liter. then you add 2 ozs to a 1 liter. ffs
16:1 is way too much oil. 40:1 from day one. No break in mix required
is it smart to use 30.1 break in and then 40.1 i use full syntethic motocross oil
Running full synthetic you could even run 50:1. Keep it simple. 30:1 is more than you need but not destructive.
In my country, the only types of gas i can find is 95, 98,100 octane unleaded and 95 LRP. What type do you recoment?
95. Run the cheapest you can get
@@HughesMotorized I beleive that it is a good opinion, because i am afraid that a high octane gas, will increase the temperature of the motor.
@@Konstantinosmo These are very simple, poorly built motors. No need to baby unless you have a very high performance engine.
Simply run them till they die & rebuild
@@HughesMotorized i respect that. Keep the good work.
I disagree. If you're building an engine for racing and high-end speed then you do want a lean oil mixture. I'm using my bike for a daily commuter. I need it to be reliable everyday. I need it to last long. I run 16 to 1 in my phantom 85. I ran 16 to 1 in my ld100 and wrote it for 2 years every day. I know a few people that run leaner mixtures. Their bikes didn't last as long. I don't care about performance when I'm trying to get from point a to point b. And my spark plug was completely filled with carbon to wear there was no Gap left and it still kept going. I can send you a picture of it if you don't believe me. Carving is not a conductive material therefore it doesn't file plugs as much as you think.
Carbon is abrasive sir. Ask any competent motorcycle mechanic
I am a motorcycle technician sir. 22 years in the business. I am factory certified in Polaris and Can-Am. I'm not here to argue with you dude. But if you want to compare knowledge I can send you a link to a video that proves with results from testing oil ratios.
Ok so I have an 80cc n the dudes been running it on 50:1 n ik that aint right my bike will start n ride for a couple seconds itll jerk like its tryna go n die out so what mixture is best for an 80cc!?!?!
40:1
@@HughesMotorized Thank you so much it means alot i couldnt find any info anywhere
Hello Eugene! I have a question. I use 40/1 (about that. Maybe a little richer) in my new motorized bike. Taking it easy and you know. Basic break in procedure. I use the “synthetic blend”.. is that ok? Everyone on the forum is telling me “40/1 but no synthetic” “30,20,10-1”. It’s driving me nuts. Is 40-1 synthetic ok for a break in? Thanks so much I hope you respond...
I broke mine was in on 40:1 the bike loved it I just added some slack to the throttle adjustment so I couldn't rev it out hope this is helpful
@@jeremypack1600 did you break yours in with 40:1 synthetic? And after the break it did you just run 32:1 conventional oil(normal oil)
helloI got a brand new engine, that rode it 24 miles and it started leaking oil from the side of the head. Do you know what's wrong? Hughes don't know if it needs to be ridden a lot more to ride it normal.
Check that head is evenly torqued down. I'll be one is loose. Tighten when engine is cold
What’s the best gas To use?
plain Unleaded is fine
I am from Germany, my englisch is Not the best. So is this mixture 40/1 for my 50 ccm 2 Stroke Kit right ? In the Manuel i can read 16/1 🧐
40: 1 yes. 103ml oil to 3.75 liters of gas
Will elevation affect ratio? 8'150 ASL
Elevation will affect air density and will affect air/fuel ratio. The fix is to run a leaner jet. Gas/oil ratio should stay the same is my understanding.
1:33 A men dude!!!! 😂😂😂
How about 50:1
Some even run Opti 2 at 100:1 so 50: w a good synthetic is fine
I am in the middle of building a bike. So for break in and after 40:1 all the way?
Yes indeed
@@HughesMotorized How should I break the engine in?
@@colevisuals111 Video coming today as a matter of fact
I been using marine lubricant 2 stroke.... I didn’t know. Its what Walmart has in bulk. Was i causing a lot of damage?
these motors are cheap. best oil is formulated for air cooled engines. marine 2 strokers are water cooled. Not the end of the world. I'd offer you swap over or even blend the 2 together to use it up
Hughes Motorized thank you. You the man hughes
@@HughesMotorized , I must disagree on this one.
Anything designated as Marine use is heavy duty.
If in the product description it says Marine Use or Gov-Spc that is the best on the shelf. A two cycle engine is two cycle. In a marine engine, the oil in the gas has the same purpose. With out it the piston is going to sieze. There are no water jackets or waterways in a typical two cycle. They are air cooled.
Water does not make its way up top to the Jug.
@@glennspears839 A boat motor will never get as hot as even a water-cooled dirt bike 2-stroke engine during normal operation because of WHAT?. A boat motor is WATER COOLED. The heat generated in a 2 STROKE bike's engine will cook the marine oil. Not good. . Keep the marine oil in your boat and PWC's.
Question, my gas scooter calls for 25:1, i believe that would be the break in period. After I can go 32:1 or 40:1. Now if I switch to 32:1 or 40:1 do I have to manually adjust the carburetor idle and fuel mix screws? If I wanted to do a weeks test for each mix and check the plugs for fouling, and do comparisons on temperatures with different fuel mix, isn't it important to adjust the carburetor each time to the correct fuel mix after it warms up??
so with any 80cc or 66cc or whatever this is the best?
Yes. 40:1 from day one
Do YOU sell engine kits that are balanced assemblies? If so, can u provide info?

@@HughesMotorized thank you for the info!! I do appreciate your help! 👍
You dont mention the ethanol amount in petrol !! Aspen has a 50 to 1 per 5 litre mix ethanol free !! Ethanol will damage the two stroke moter
These are cheap, poorly built engines. Build a $10,000 engine and then worry about it. Really, you can run used motor oil in these. Ethanol will not hurt these. People even ran used auto oil in 2 stroke motorcycles for years no issues. Don't overthink it
@@HughesMotorized ethanol is damaging all kinds of engines !!! The china doll moter works better at octane level 91 & no ethanol so im trying aspen 50 to 1 premix to see if my moter likes it & if not i will just carry on putting petrol with 5 percent ethanol that is damegingall kinds of two strokes mainly garden tools etc due to ethanol !!!
