I have an 028, with a new carb kit, (and I DID pressure test the needle), good spark, good compression, and new plug.
As soon as I crank on it a couple times, it seems it is just sucking fuel into the cylinder and soaking the plug.
This is the first saw I have dealt with that has the impulse line, so I'm not sure how it's supposed to act.
I discovered that someone previous to me had inserted a set screw in the vent line from the tank, so I replaced the line after determining that this was what was causing a pressure build up in the tank causing a hissing that I could hear through the plug hole after cranking it.
Still, it seems to be sucking fuel into the cylinder.
When I checked the impulse line, it pulses, but after a couple cycles of the piston ends up with positive pressure, but the thing that has me buffaloed, is that vacuum applied to the fitting on the carb for the impulse line sucks fuel directly into it.
Do I have a bad carb or is there an issue with the impulse line?
