just like how the title says anyone know the fix or had the problem?
Dies when picked up?
So starts okay on the ground- still on high idle? Then dies if lifted straight up to a working height without altering the orientation of the powerhead?
As you lift are you kicking it from high idle to run mode- or is this done before lifting?
Kill wire getting grounded out from slight flexing?
Should have added to it a bit so when i set it down at idle when I go to pick it up 30 sec later it dies even if I pull the trigger on the ground without even touching it just pulling the trigger it dies and other time I can shake it up and down when I’m holding it but after I set it down it dies
Mabby I will check that
It would be at idle not high and just lifting it straight up and down off the ground
L setting on the carb has done that to me before. On a 440 coincidentally, but an OEM one.
Low speed screw might be too rich causing fuel to puddle when it sits idling.
Still don't fully understand..... but, it dies when you open the throttle? Or it dies when you do not hit the trigger but just pick it up?
Will it start and run on high idle, but as soon as you pull the trigger to pop the choke selection lever up to the run position it dies?
could be impulse line or the carb or the kill wire switch or something else if you don’t describe the situation well and use some form of punctuation you won’t get much help garbage in garbage out
Will make a video when I get home it’s kinda hard to explain
The way I read it is the saw works fine, starts, cuts, etc. Then you set it down at idle and it idles fine until you go to use it again and it dies when you pick it up.
yes that’s what I’m trying to say
Sounds like what Kevin described. Loading up with fuel at idle. Close the low speed screw a quarter turn and see if the behavior changes. You may have to back the idle screw out a touch after you do that.
Ok I will try that thanks
My Wild Thing did that last year. It was a combination of an incorrectly set metering lever with a leaking check valve (cheap chinese carb), plus an air leak from a bad crankshaft seal.
Like was mentioned, fuel is forming a puddle in the crankcase. When you pick up the saw,the fuel that has puddled gets drawn into the cylinder and it makes it to rich causing the saw to stall.The fuel that has formed a puddle is caused by worn rings. The saw will continue to run however at idle, the lack of velocity caused by worn rings allows the mix to form a puddle.A small adjustment on the low side may help to alleviate these symptoms.
Thanks i will try that it and the saw is only pushing 100 psi but it runs it needs new c/p
Well if that had been mentioned first up it would have saved a lot of guessing!
