Poulan 4218AV. I start it with choke fully open. It runs fairly fast, but when I move the choke to half, it runs wide open, as soon as I hit the throttle trigger it dies. Any suggestions besides wrapping it around a tree.

Hello,

Yeah, your problem is that it is running lean (fuel), try changing the fuel by dumping the entire contents of the tank in to a oil pan, then check for water or trash. Second replace your fuel filter. Then mix some fresh fuel and try it again. Also double check the carburetor mounting fastners for tightness, if you have a loose carburetor it will act that way too. It **** too much air and runs lean.

Hope this helps,Matt

Hi

have you checked the muffler for restriction and ex port for blockage

have you checked fuel filter is ok and the fuel lines are ok

is the spark ok and the timming good as in the flywheellkey ?

quick test pour some 2 stroke mix through plug hole , fit plug, if fires assume compression and spark are good , the pour some 2 stroke mix into carb throat via air intake ( with filter off )

if it fires again can be pretty sure you are dealing with a carby issue or intake problem
with the latter this could mean a air leak from ie carb joint , cracked manifold block, barrell gasket , c/case joint , crank seals only way to find this out is tp pressure and vacuum test c/case with 7-8 psi of pressure and about 20 -25 inch in vaccuum

if so then i would suspect a possible air leak @ carb manifold block ( check its not cracked )or maybe the barrell gasket is leaking check the bolts are tight

then pull off the carb and check the diaphrams are soft and pliable and are not damaged
chck the fuel inlet screen it maybe not letting fuel mix through


see if this helps
