My 240 starts like a champ. Going full throttle kills it. Gotta feather the throttle to use it. (brand new mix in it every time, air filter is flawless).

good job explaining the cleaning and rebuild the carb, had my 235 apart since last fall and sitting in a bucket, and needed your expertise on how to, cause I was scratching my head on how to get it back together and running again.
My 240 had a starving problem . When I took it appart,I foud out that the feed line to the carb is a double wall conduit and the inner one had pinched it self by the vacuum force ot the carb. . .It has run great ever since I've replace the tube. .
I had the same problem. Perished in ethanol, like all the rest.
Should do the skip to which x amount of time, so's to view which process of step(s), placement points.
may have been long but in a good way you covered everything thanks
Is there supposed to be two filters, one on the carb feed and one on the primer return line? I have to replace all fuel tubes on my 240. I found one filter and one fuel line splicer. Not sure which line they csme off of. I suspect th one off the carborater. .
@allenmaceyjr.243
Only One Fuel Filter on Carb feed
The splicer is for the return line and it goes inside the fuel Tank.
It's just there to keep the fuel line from coming out of tank easily thru the Hole in tank.
Great video. No need to apologize for the length.
I’m doing this for first time. Replaced all 3 fuel lines and cleaned carb w brake cleaner. I get it to start but bogs down when I pull throttle and won’t idle. I had I running for several minutes but wave to keep the throttle going up sneaky down.
Can’t decide if it’s worth buying a new carb or trying a rebuild. I don’t have comprehension tester. Feels ok.
I’ll prob throw it in the trash. I can’t afford a new one. I’m screwed I guess.
Great video though. Thanks.
It bogs when you throttle most likely the Low or High Speed is to lean or Rich.
Or the Carb fuel passages in carb are still stopped up. If your certain the carb is clear and good. Need to adjust Carb. The video I have on this saw is part 2 that shows you where to put those screws after Carb rebuild. Saw should run decent just putting those screws close to factory setting that is in Part 2 Video. If saw will not run at factory settings. More than likely Carb is still plugged up somewhere. In part 2 video shows you how to check to make sure carb is clear by removing the adjustment screws and spray WD-40 thru the low and high speed. Video shows where WD should come out.
Sartin Garage thank you. I watched all 3 videos twice last night. I’m going to order the kit from eBay and give another shot. I prob didn’t clean carb very well. Only the surface. The kit is any about $15. Seems too cheap to be true.
Thank you for the replies. Very helpful.
Sartin Garage and then there’s the idler screw. What’s the factory setting on that? I lost track of it trying to adjust.
The high and low requires a special tool but I think comes in the kit.
I’m not all that mechanically minded but as I plan on getting an older model Husqvarna chainsaw
this has been really useful, especially at the measured pace.
*Subbed* 👍🏻
What model ?
@@sartingarage8045
Perhaps a 372, incidentally what Fuel/Oil Ratio do you favour?
50:1 is the fuel mix ratio for all Husqvarna Equipment. I run the Husqvarna 2 cycle Oil in all my Husqvarna Equipment. Never have issues. Husqvarna 2 cycle oil already has fuel Stabilizer in it also.
@@sartingarage8045 Thanks for that info sir and have yourself a Great 2022.
Thank You for information and advice
I’m learning 😊
Great video. Keep them coming.
Thanks for taking the time to make this. It was just what I needed to fix my 235 💪🏼
Excelent explanation!
Great video thank you for sharing. May I ask how come you did not go ahead and replaced the rest of the fuel lines just in case?
Actually I did change the other fuel lines.
Just not on video. The camera battery had went dead and I didn't get the footage
@@sartingarage8045 oh I figured you did. Great video now I feel confident enough to take mine apart.
Just need to know how many turns out for needles valves after rebuilding carb.
19:50 in this Video
This saw I would start at 1 & 3/4 turns out both Low and High
Awsome video!
My wife would ask, you have an Axe, right?
My wife would ask, "But you have like five other saws, right?"
Good videos! I have a 235 and I'm in process of fuel line replacement and carburetor rebuild. The fuel lines that are in the tank have a slicer on each line. What is their purpose? Do they affect/regulate the fuel and venting or just stopping the lines from being pulled out to far? Do they need too be put back in place or can they be discarded?
Thank You, Darin
You can do it Either way. I'm not real sure why they put those connectors in there. Some equipment has them, Some dont.
Maybe just to keep from pulling fuel line out of tank incase a snag or something.
Brilliant video everything i needed to renew my fuel line was in the vid. Thank
tq for sharing the knowledge. god bless you sir.
Mines a 236 but lookin at your video it's pretty much the same mines bogging down so I think I'll change the gaskets great video and well explained
Since I had to buy a new carb, and it was removed, what should factory setting be on the black (T) adjustment?
Thank you for the video. Do you know how to replace the fuel tank vent and check valve on a Husq 235? When i was working on pulling the air purge hose beside it, I accidently pulled out the check valve.
Yes There is a vent like screen on top of the check valve. The check valve/ Duck bill just pushes down in the fuel tank and vent screen pushes down on top of the check valve.
hi thankyou for that i am looking at a mates chainsaw and this has help alot. but can you tell me what the top throat does
👍 2 more questions, I purchased a aftermarket carb kit with everything mainly just for the accessories and carb tool. While I was waiting on my zama rebuild kit to arrive I installed the aftermarket carb just to see how she would do. I didn't expect much since the whole kit was $15. It was worth it just for the accessories. I have fuel coming out of the muffler. Is this a diaphragm issue keeping the needle valve open and if fuel has managed to get in the crankcase how do I remove the fuel?
Thank You for your time! Darin
Yes either the the needle is stuck open or not seating correctly. After you start engine should blow excess fuel out muffler from crankcase.
i am talking about nuts near the air filter
Carburetor sets on studs then air filter base then 2 Nuts hold it on
This is great video and has helped me a lot, though I still have a problem. I am pulling air into the fuel line at the carb. I have new fuel line, new filter, new primer bulb. I accidentally ripped out my duck bill so I replaced that and the brass(?) Plug. I rebuilt the carb with the brand name kit. When I put it together and prime I do not pull much, if any, fual through and end up pressurizing the fuel tank. It's like I'm pulling fuel through the jets. Do I just have a bad carburetor? Any suggestions are appreciated. Thank you in advance.
@chrissaunders8284 You are sucking air from somewhere or your fuel lines are connected wrong to primer or
I'm thinking the Carburetor Gaskets are not sealing up, Also is your needle and seat sealing up. You need this leak down tester.
This is the link to the one I use. They help alot for issues as your having
amzn.to/3FxX7Ba
Have you ideea what is the purpose of doble hole carburetor? I am searching for a wile on the internet but no answers...
It's a 2 barrel carb
There are several reasons for a 2 barrel vs a 1 barrel
After a certain engine size 1 barrel doesn't have enough air flow without making the Carb huge
And sometimes each barrel will supply air to one cylinder and the second barrel will supply the 2nd cylinder
I need to replace the duck bill valve (found it in the gas tank) and vacuum filter, BUT everything I have tried I cannot get the small filter out as it is wedge tight between the surrounding wall.
Duckbill goes in from top next to carb in very back corner where carb is.
I use chain link fence tie wire to remove fuel filters. Cut off about 6 to 8 inches, bend one end to a U shape, Maybe in your case a 90 degree would work better.
@@sartingarage8045 Tried large versions of dental picks and bend fish hooks/ Nothing worked. I am now trying to drill it out. This chainsaw appear to be a throw-away.
how many turn you use for the black screw
thank you
Both Low and High Speed Screws are 1 and a 1/2 turns out. Most of the time this gets you running and can tune from there.
If you have trouble try 2 turns out and try.
1.75 SPEED FOR THE WIN !!
Nice videos. I was given a 235. Is there supposed to be a check valve inside of the tank? If so, where is it attached? I was told there might be a vapor lock issue. The purge bulb has a small hole so I ordered a replacement.
Check valve is located to right side of carb close to cylinder
Should there be a duckbill on the purge line?
There is built into primer bulb inside of the primer assy...
Very well explained good camera work can see everything excellent.
Thanks for the great video. 👍
Great video. Thanks for the detail.
I found the carb rebuild kit on Amazon for Husqvana 235 is it the same as 235e? I have the 235e series not sure if they are the same.
Most likely will be the same Carb kit
I look at the numbers on the carb
On a Zama carb there will be C1Q stamped in one spot on carb, Then in another spot will be stamped like S68. Then you put those numbers together with a dash in between.
So C1Q-S68. Then just search for a kit for that carb number
@@sartingarage8045 thank you. I could only get the carburetor to come up was looking just for the rebuild kit. I went ahead and ordered from Amazon to see if it fits. I think they should be the same. (RB-149 kit). I think the on on your video was 235e series as well. I also got the spline driver. Thank you fir your help.
So i received the carb kit and installed it. Your video was of tremendous help. I changed out the hoses the one that goes to the tank and the line with the filter. I noticed the two hoses were two different sizes. Is that common? The one that went to the tank was 3/16” while the one with the filter was 5/64”. I had to use a universal primer bulb hope it works the same.
Yes they do use different size fuel lines sometimes. Universal primer is fine.
They use that primer on many different brands of equipment.
@@sartingarage8045 thank you i will try and start today. the carb look pretty clean inside and gasket came off easy with very little resistance. Did not have to clean the carb at all. The spark plug looked decent i did use sand paper and removed a little of the residue and tested the spark plug to see if it was sparking when i pull the lever. I did get a spark. Do you think i should go ahead and replace the spark plug even though it is sparking?
You don't have to change the Sparkplug.
I always put a new Sparkplug in all my equipment I repair for a customer.
But not so much on my own equipment.
@@sartingarage8045 so i rebuilt the carb and started the chainsaw. It ran slow and then died. I started it again and then died again. I changed the spark plug tried again and nothing happens. Not sure what else to check. I took the carb apart to make sure i did it right and i did thanks to your video.
If your sure you got the carb jets low and high side cleaned out, where did you set your low and high side adjustment screws at. May need to back them out another quarter turn or your are probably dealing with a air leak, Intake boot , hole in fuel line, Intake Gasket leak or Cylinder gasket leak.
I would've cleaned my saw before bringing it to a shop to be worked on
Most people dont clean it before
Maybe I should start charging a saw cleaning fee. They can be nasty to clean.
Blowing Oil and saw dust mix all in your face and clothes
hello
do you know why my carburetor nuts will slack very easy even i tight enough
thank you
That's strange, Never had that happen before. Maybe after tighten use BLUE threadlocker.
DO NOT USE RED
@@sartingarage8045 thank you
Great video thanks
I must try degreaser I've always used carb cleaner..
I will eventually do a video on the cheapest best stuff to use.
Good videos your doing bud. What degreaser are you using also do you do the same on lawnmower carbs. Or are you using something different on them carbs.
Thank you !! I've been planning a Video to tell people the best thing to clean there carbs in or atleast I have had really good results using and have used this for 15 or more Years and its really cheap to buy.
I don't want to give it away just yet.
But the video will be coming soon
Hey bud could you please do a video on what you use
Give me a few days and I sure will
Thank you
The throttle!!!!!! Don’t show people to just rip the throttle off. Make an edit and show them to open the handle and disconnect it before everyone ruins their chainsaws. It’s three screws. Please.... they’re gonna have to do it to reassemble anyway
you unscrew at 6.14 in your video
