Did you put a new plastic one on or the new metal one?

The plastic ones are known to give problems over time, as evidenced by your experience, and the metal ones last the life of the saw usually.

i put a metal one on it but that wasn't the problem i thought it was fixed but its still doing it not as bad but enough i cant keep it adjusted right

when i got the saw it had a cheap aftermarket cylinder for a 350 on it, i put a oem 42mm piston and cylinder on it the cheap cylinder did not lean out when sidways but did not have any power

Three words, pressure, vac test.

don't have a vacuum tester i blocked the exhaust and intake off and put 15psi in the spark plug and sprayed it down with soapy water. does anyone know if you can put the 42mm cylinder on a 2010 346xp with no issues

Buy the Mighty vac, you're lost without doing the test, and invest in a decent compression tester. You have classic signs of a vac leak, any work you do will be a waste and a crap shoot at best.

Mighty vac

thanks ill have to pick one up

 

[don5477]

i did notice a difference between the 2 cylinders idk if that would make any difference or not

in my opinion the saw needs a vac and pressure test to rule out seals,case gasket,cylinder base gasket,intake boot. im afraid your chasing your tale if you can not rule these things out for certain in order to move on to fuel lines and carb functionality. also if the saw doesnt seem to do this until it gets good and warm you may need to think about getting it warmed up and acting up then look for the problem.

They interchange, no problem there.

They interchange, no problem there.

Why would you?

 

[don5477]

Why would you?

when i got the saw it had a junk aftermarket cylinder and i had an older 346 that has a good oem 42mm cylinder on it the older 346 is not usable all busted up

 

[don5477]

i got this kit to pressure-vac test the saw, what should it hold and for how long on pressure and vac

Now you're talking. I meant no disrespect on the 42 mm 346, just wondered why you wouldn't go with OEM 44.3 mm, their price was lowered this Jan to about 105$ delivered. I just put this combo on a 350 chassis and I can tell you this saw rips. Lightweight , powerful, good feel and balance, my new favorite firewood saw. I understand going with what you got but if you get the chance I would suggest you read up on the threads related to the 350 and the 346, lots of good reading.
