Re: Jonsered 2040T over fuelling?
« Reply #10 on: June 03, 2014, 03:20:48 pm »

I tried a complete kit over the weekend (gaskets, needle and screen) and it is still flooding. Very frustrating.

I followed setup procedure for walbro wt carb and have the needles at 1.25 turns out. It floods so fast from opening the fuel line that I think needle adjustment seems unlikely. Will try though.

The carb to cylinder gasket is not looking great but I guess it must seal as the pulse is still good - I am getting too much fuel rather than not enough.

Also, when it does run it seems to leak a little fluid from the crank seal, chain side not generator side. It's not chain oil as I have blocked the port. If I am loosing crank case pressure, will this effect anything?

I had a stihl 029 in that would flood itself  no matter what I did to carb.  Finally gave up on that carb and  put the same new rebuild kit in another carb and all was fine then.  My WAG = I think the seat is causing the flooding, needle seat has ware or something.



Try another carb.

Question I tried looking up a jonsered 2040T IPL as you have listed. Nothing.
Is this saw a jonsered 2040 rear handle or is it a T = top handle?

Saw is a 2040 Turbo, hence T.
That carb looks correct. I have certainly spent $30 of time on it!
I will try that. Thanks.

Looking at that jacks link it says fits these too. Might look for a donor off these saws.      Poulan 2200, 2750, 2775, 2900, 3050, 2500, PP4620AVX, PP295 Chainsaws

if the welch plugs have been messed with, or there is any corrosion under them that's pushing them out, it will cause flooding issues.
this is the same saw as the Husqvarna 40-45-49. lots of parts everywhere for these.
you do have the spring under the lever don't you?
are you sure it's the correct needle? there needs to be fuel pressure to 'fill' the metering side of the carb, and it needs to be quite a bit to do so. so if the diaphragm is in the right place, and all corresponding parts are ok, there shouldn't be any fuel getting in unless that spring is either missing or somebody has messed it up. not much to these carbs to cause problems. they're not rocket science. so long as all the parts are in place, and properly, there shouldn't be any issues like this. this is one of the most reliable carbs out there.

regardless of the flooding. if a crank seal is leaking fuel out no matter how full the crank case is, that seal needs to be replaced. if it's leaking through the mounting bolts, the bottom end needs to be re-sealed which means a total tear down. you have more work than just the carb. and running that saw with said issues will burn it up quick. maybe it's time you visit the local small engine shop for an opinion from somebody who can have the saw in front of them for a proper inspection. before you waste more time and money.
when I grow up, i wanna be an adult.

I don't think so, as I recall it those Huskys are Swedish made - while the 2040 is a cheaper Poulan made saw, similar to the Husky 41.
