Carb gaskets and diaphragms are installed correctly. Reed petals look tight. Reed block has no cracks I can see.
After dunking in water I discovered it was leaking between carb and reed. Took it down and found the carb gasket had slipped when some idiot, me, reinstalled after rebuild. Got that fixed and now it runs well until you turn it sideways. Definitely got a leak, maybe one or all three seals.
Does anyone know how to pressure test a poulan 306a? Can’t get any pressure using my mityvac
Started tearing it down to attempt to discover why. Took the oil pump cover off; mostly for cleanup. Then used my compressor to push some air in through the modified spark plug I fabricated. Lo and behold, air was coming out of one of the screw holes for the oil pump and the end of the crankshaft. Yeah, I know, totally weird. Put bolt in the screw hole and tried the mityvac again. Really blocked most of the air but still can’t get pressureStill no dice.
I got two options -
one-replace all three seals and hope that fixes it;
two-toss it. Very tempting.
Out of the dozens of saws I’ve rebuilt I’ve never run across anything like this.
Would dearly love to hear from someone that is totally knowledgeable about this saw. It’s got me flummoxed for now.
Thanks,
Jerry
