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. Still no dice but not so much air coming out.
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.
