- In this video, the Odyssey runs!!!
After completely rebuilding the engine on this 70's go kart we decided to finally get everything back together and reassembled to get this Honda Odyssey one step closer to driving for the very first time!
What we did in this video was completely installed our 250cc 2 stroke as well as completed all of the wiring and installed finishing details like seat belts, plastics, and other cool stuff.
Thank you guys for watching and be sure to stay tuned for the rest of this build!

The original fuel tank used a pulse pump to get its gas. There's a nipple on the back of the engine a hose connects to and the other end to pulse pump to gas tank
I like how it has two spark plug in one coil so if one spark plug fouls you can just move the coil over to the other that's freaking smart awesome.
Its not actually meant to have 2 spark plugs, from factory it comes with a bolt plug in the other hole, from what I have read the other hole was originally designed for a compression release for a different quad.
I wonder if you could run both spark plugs and improve the burn
Finally, I'm glad it's running
8:35 just love how Daniel jumps while starting the engine
Hope fully it. Will stay running
Best use for saw horses right there ladies and gentleman
Cool guys... takes me back to 1986 when ‘i used to ride those and ATC’s... AWESOME stuff
Love y’all guys been here from the start
after checking the jet size check the needle height setting ( clip is in wich slot to allow fuel to flow through main jet as slide opens). check Reed valves if it has that option for broken or week ones, points gap ( controls timing and spark), also I found cleaning the carb in a ultrasonic cleaner works excellent ( little Dawn ,with lemon shine works good) harbor freight sells them ( not sure about cleaning plastic parts tho so I left floats out hope this is some help!!
Wow the Honda Odyssey sure has changed
Sounds like my childhood when it runs!
Never owned an odyssey but I have a 2 stroke atv(lt250r) and I was having issue with idling and in consistent power so I cleaned the carb a billion times and rebuilt it about 4 times and it never fixed it but as soon as I got a new carb it was like a breath of new life for her
Brian Reiff Yeah I’ve been looking into a Mikuni swap or something might be the way to go thanks.
Love the videos odeysy videos are my favorite keep em rolling
She is a runner boys!!!!
sold 11/10 this looks awesome
Sold mine yesterday. Gonna miss her
Try a smaller main jet in the carb. By switching from 20:1 to 32:1 premix, you are leaning out the oil, but your pushing more gasoline and actually enriching the air/fuel.
I had a carb issue on my dirt bike for a few years. Just replace the reeds with some Boyesen Power reeds. After I did that it ran flawlessly.
If its too rich the smoke is black, oil smoke is blue gray color, the smoke you had on that first start was clearly oil smoke, blowing a lot of smoke when first started is very common on engines that have been newly rebuilt. Also in many cases if you fire both spark plugs you will have a noticeable power gain over running just one plug. I think a plug in the combustion chamber that isn't being used will probably be fouled if you tried to use it later. You need to find somebody that is used to tuning 2 strokes to give you advice on tuning, 2 strokes can be cranky if not set up right.
I've never had a go cart, it's my dream to have one
Looks really good, my friend has a odyssey with a full roll cage idk the year but it’s cool.
Just today I had kinda the same issue with my fl250. I couldn't get the idle right and the idle screw wasn't doing much. Turns out I had to get the throttle cable adjusted just right for the idle adjustment screw to work right. It also could be because the slot for the idle screw on my side is so worn out but it's worth you guys trying
Never worked on a two stroke but if you have rebuilt your carb multiple times I would check that the needle and seat seal by blowing where gas would go in and see if air comes through when you lift the float up. Another thing if that's not it is jet size if you got a jet in the kit it might be quite a bit two big but barely noticeable to the eye see if the old one fixes it. Love the builds and hope this helps. I might put up a short riding video of my 1985 Honda atc 200s but it's kinda hard to film by yourself and I love the intro maybe you could help me with some ideas on how to start a channel. Thanks. I forgot some two strokes have reed valves which I have heard can cause running issues but again I have never had one to know if that's it.
N1ck0145 Garage 👎
Look into a ratio cup. You can use it to mix up to 2.5 gallons of gas and it has a wide range of mixing options from really rich to really lean. Your nearest powersports should have them
Hell maybe even months.....if you keep pumping out these videos
So excited to see it running 🤙🏼
Hey man I’m watching you on tv right now that’s awesome idk that y’all was on tv but I do now
It seems like it could be two things. 1:Your carb settings and cleanliness or...
2:The exhaust pipe...
Two strokes rely on the shape and length of your exhaust pipe. It uses the pulses in the chamber to reverberate pressure waves back to the combustion chamber to help compression. That is most likely why its falling on its face when you rev it up. They NEED back pressure at all rpms but even more so the faster it revs. They have a powerband with a sweetspot and it feels kinda like hitting boost when the motor finds it. Depending on your rpm, displacement, exhaust chamber length/width/volume, fuel mixture and and bunch of other stuff, you're sweet spot will change. But you NEED a chambered exhaust of somesort to make'r 🏃 run right at all.
It might be worthwile to drag it by a bike shop that deals with dirtbikes and just have em go over the basics of tuning a 2smoke. They really are their own unique animal.
Sounds like the main jet, If the symptoms get better with the airbox off I am correct. It sounds stupid rich, as long as everything else is adjusted to manual specs it is most likely your main jet.
Try adjusting the fuel/air ratio screw and also check the new Jets and make sure they are the same size as stock
TuxedoRooster Ill take a look. Thx
Build Break Repeat yep no problem, and if that doesn't work then check the bottom end for gas because sometimes gas can pool up in the bottom end of the motor in a 2 stroke and it will run ok at idle but when you rev it up it will splash that gas around causing the engine to run very rich or die
You should do a pressure test on the engine to make sure it doesn't have a faulty crank seal. There are good UA-cam videos on pressure test on 2 stroke. Also if it's original carb buy new one. Buy keihin only others are junk in my opinion. If reeds are original replace with new ones
Also castor927 mix 40:1
Joe Hicks I have worked on these types of engines for years, looks like a bad crank seal to me. Not sure what your budget is but I would go with a complete lower rebuild.
that thing sounds Wicked!!!
Looks cool nice rebuild. Thanks guys.
Some models had reed valves check the intake see if there's a reed cage they may be worn out and need replacing.
1 more thing a 2t is the simplest motor to learn how to rebuild, but it is a black art to tune one. Piston port height vs case port timing,single base gasket or double ,shaved head or not shaved. Exhaust port height vs intake port height. Read valve stiffness , single reed vs 2x reed. Colder spark plug or hotter. squish band in the head, For 40 yrs I have been playing with them and still learning . Don't seek help too much from the internet because what work for me won't for you. Best to find some 2t tunning books and get to reading . It will blow your mind as to how much what looks like a simple motor takes to tune.
Like Joe said, check the crank seal. It's probably pulling oil from the crankcase.
you guys are good!
Seems like a fuel related problem try different adjustment on the air fuel mixture. Reeds. Seals. Clogged exhaust. Good spark? Firing every time?. I'm looking forward to when you find out I got a old dt 250 that kind of has the same problem but havnt had time to tinker with it . Good luck
i would suggest wrist straps for when you flip witch me and my friends can testify to will happen and believe me you can't hold on tight enough
guys. i think I know what the problem is. Check the charging coils that are with the magneto. those produce the energy in the engine. if the resistance is out of spec they produce some of the symptoms you describe. I have a Yamaha Dt 200 with bad chargin coils and it was a pain in the ads to start and when it did it run without a lot of power. also it backfired when trying to start it and also kicked back. Measure the resistance of the coils and see if they are in the ok range. Lucas from Argentina!
Great Job! Impressive! Looks nice!
Awesome thanks
If it flooding the engine from sitting over night or something the float needle may be jammed or have some dirt on it give the carb a couple of wacks with a small hammer should get it unstuck
Give it a good run before messing around with the carb mixture as it may take a while to burn the petrol out of the crank case and exhuast it will smoke until that's burnt
My old yamaha 2t floods the crank case usually starts tho but smokes like hell for about 5 minutes till all the petrol an oil is burnt out
It’s a 2 stoke they can’t stay idling forever you will foul plugs.. try putting it on a stand and giving it some good high revs if it still does it try different fuel mixture
Drop the needle all the way down or get leanner jets. Check timing. I have had motorcycle engines shear the keyy for the magneto and slip timing
Finally im soo glad I thought y'all forgot about it😂
Never messed with that particular carb, but I would try leaning it out for sure
You might need to re jet your carb. It's not as hard as it seems, just watch a good video on it and you'll learn a lot. Cameron Neimela makes a great video on how to jet two strokes. Also maybe a new correct coil might help😂
Put the needel set on the throtal float in its lowest setting. That will slow the fuel down its under the throtal spring
I forget the exact name of it its the throtal flapper that slides off the cable
fuel line too large? gas tank too high? look at ANYTHING you changed from the factory setup
would make one hell of a weed eater
Love this channel . Keep up the great videos .
That thing is awesome
It can be the jet or it can be the exhaust, the pipe is clogged? I had this with my moped. I thought it was something with the jets, then i started looking further and i started it without exhaust and it ran good. So you can try that.
btw..was the fuel tank ever that high,Stock?Maybe float check, can't slow flow.I don't recall a tank there.Maybe shut flow down to 1/3?
So it’s running to rich and you need to either lean it out with a smaller carb jet or you could try to adjust the needle in the carb that is used for mid range I believe you could just move the clip one or two places up
Nice!
there is money there is peace
I wish I had one those are awesome 😁
Adjust the valves while at top dead center making sure the timing is correct.
Sean Signer two strokes don't have valves lol
I used to have one of those.
Good nice
I don't know if that engine has reeds but check them they have to have a nice seal or you get hard starting and low power also check timing.good luck with it young fellas hope it nothing serious
When it comes to 2 strokes and it runs like that , with little power and doesn’t always want to run right, it’s normally the jets. Go into the forums and try to find what jet and pilot jet you need for your weather and altitude
it almost sounds like you got your fuel mixture off I seen the amount of oil that he had in that little plastic cup that was a lot. Are you sure you got it right? You can buy a plastic container from any Napa or O'Reilly's and it will show you the measurement for the oil. It will say fill the two-stroke oil up to here for this many gallons of gas at this ratio. There are different levels all the way around the jar for 50 to 1 and 45 to 1 and 40 to 1 and so forth
Todd Bearden Ok we’ll double check. I’m gona pick up one of those oil cups too that takes out all the guesswork thanks.
Yep definitely check this out before pulling anything apart.
Todd Bearden I thought the same thing, I run amsoil at 50 to 1 in a 2gal container and that takes right at 5.75oz. That was a lot of oil in that bowl and a 1gal jug.
Tyrone Pearson it is a more of a heavy load 2 stroke so I would imagine that you would do about 20-25 to one
Could be a crank seal or spark, spark plugs can go weirdly fast on two strokes especially if the mix is too rich
How is the wiring for the 79?? I lost spark on mine and not sure how the wiring from the case to coil should be let me know!!
Do these symptoms happen with a good pipe on and in the power band, that could be a problem
It must be the fuel-mixture, try using a different carb of the same diameter as a cross reference
Sounds like when your metering rod is set too hi. Don't know if the one you have is adjustable. The pilot jet is only good from idle to about 1/8th throttle. It starts and idles so you are close there. The main jet comes into play after 1/8th throttle if it is bogging it is too big or metering rod is set too high. If it is spitting and sputtering and exhaust is getting hot under throttle ,the main jet is too small, dirty,or metering rod is set too low. Also if you flooded the plug it could be firing but misfiring. Would need a new plug. Hopefully this helps
Damn that's pretty impressive of you kids to bring back that old oddyesee like that....is that the actual frame? And factory parts....they look brand new for 40 yrs old
Best stuff ever
Is there a way to adjust the ignition timing? Or how's the reed valve?
bryan terrell We are probably going to take it down to adjust the points, thanks for watchin cooter
What gasket did you use to seal the split rims? The ones I used leaked terribly
I forgot to mention if the tank is above the carburetor you don't need a fuel pump. It only needs it if below carburetor. Could be your flooding problem
That's what I called jump start LOL
Hi guys it sounds like that two stroke engine is bogging where you are running it to rich. i think you need to adjust some things on the carb to get it running right. I hope this helps you guys out on getting it running right :)
A 2 stroke just smokes
If the motor is leaning from front or to back to much. Fuel will run n to the motor try tipping it back some
That could be a wrong size jet or the wrong air fuel mix, you can use a colourtune to sort that out
Dont forget the airfilter
I can't really tell you anything but I have a two stroke street bike that pers like a kitten and I could help. One thing don't put that much oil in the gas bc it causes the motor to work to hard and it won't run right and it will smoke allot.
#1 Look at the spark on the plug if it is nice and purple its not a spark issue
(Test by holding the spark plug and pulling it over, it works all the time)
#2 too much oil added, or wrong type of oil
#3 to much of a resisted fuel filter
#4 fiddle around with the Air to Fuel mixture screw
#5 carb is warn out, replace
Power to ya
It would help if you put a air filter you don't need to be sucking trash through the card and it's a better adjustment less air too much fuel fall out the plug
1st I think you didn't mix 32 to 1 but might have 13 :1. 2nd check the ignition timming , it sounds early 3 install pipe 2t needs back pressure.. 4 check crank seals , if gear oil is getting in or air on the other side then it will blow up. 5. adjust the air /fuel mix screw might just be fat on fuel. 2t like to be lean over fat on fuel. 6 what position do you have the needle clip at for the carb slide ? Start in the middle and try up or down. 2t's have lots of tunning adjustments that you can make . Just do one at a time and work back and forth Altitude can reek havic so even set up as per the manual at sea level it won't work well at 1000 ft above sea level. Small tuning adjustments can make a world of difference , down to a dirty or clean air filter , having a air filter or not. Always remember a 2t will always run best just before it blows up . So when you get it tuned make it a bit fat on fuel to keep it alive. Coffey double cream spark plug reading is perfect. But you have to run it wide open and shut the motor off and coast to a stop engine ,,,not running down to idle to get the perfect reading.
Good luck in your adventuers of the wonderfull world of 2t tuning lots of good book to read and lots of motors blown up to learn how to get it right.
Need some help I have the same oddessey with no fuel tank went with a gravity fed fuel tank with a pulse pump but am having difficulties with the configuration need help as any info on why my pull start is so difficult to pull
yeah get the cr in the back running to
Real nice
Check your needle and seat and did you replace the Reed cage?
This nigga inhaled that smoke and no one pointing that out?💀😂😂😂😂
It sounds like it needs to be jetted. Check out Cameron neimelas channel. He has a really detailed vid on jetting a two stroke and another on reading a spark plug to know if it is lean or rich.
Cool!
How fast do you think it goes?
i have a fl250 honda odayssey and wanted to know if someone has a picture of what gets conected to the carb and to get spark
when you removed the stator you changed the timing .did you retime it when you reinstalled the stator
try to replace the reeds in the intake
lol. stank the garage up good!! :)
Low/idle jet adjustment possibly
Should've ran 20:1 to break it in and then switched to 32:1
TuxedoRooster We haven’t ran it that much yet, I’ll throw some more oil in her when we get it running right. Thanks.
TuxedoRooster actually 32:1 is perfect for breaking. That's what I'll mix when I break in my 250 2 stroke
Tyler Lewis on a newer engine I would agree but since this is such an old motor and the regular oil is supposed to be 20:1 I would think you would run that at least to break in the motor. Plus a little extra oil can't hurt but too little definitely can
I disagree 2-stroke oil has evolved over the years. Today's modern 2-stroke oil is a lot better.
You need to ride it like you stole it and get the engine up to high rpm to clean it out 2 strokes don’t like to idle so you just need to start it and nail it just basically clean the granny dust out of it
