I decided to help a friend out that helps cut firewood with me on occasion just for something to do, by figuring out why his 445 is real doggy, at my cost since I sell the firewood, he just helps for free. It starts good and idles good once warmed up, but out of wood, when you accelerate it a little (near half throttle) its ok, but once you try to hold it wide open it bogs and sputters down and will eventually stall out if you keep trying. In the wood it acts the same but wont stall out, just real slow and bogs down to where you have to come out of cut and then restart.
From my first inspection it looked like it was getting choked out by the cruddy air filter, and he said he's never changed the fuel filter. 125psi cold compression. spark plug and piston top is tan/light grey, a little lean looking for my preference. Got those ordered and installed, and cleaned up the intake area of built up crud, no difference.
Fuel line didn't feel too spongy, could that be collapsing? fuel filter looked decent and I flushed out tank.
Are the zama c1m el37 carbs a pain to rebuild or nothing special? Says he uses 91 octane but not sure whether he gets ethanol free or not, so I'd be wasting time just trying to clean it in that case right?
My next step was going to be the fuel line and carb rebuild...$14 for kit, or $31 for new carb, if I spend an hour dinking around rebuilding carb I may as well buy a new?
