I went through the fuel hoses and they held vacuum. I did find a leak at the primer bulb base and replaced it. I thought I found the leak but I was wrong.Impulse for the fuel pump goes through the intake so no pulse hose. I didn't rebuild the carburetor. I posted on another site and got some good information. The initial numbers in the 80's should have been an indicator that the saw was pushing more fuel becaise it had a leak. The crankshaft bearings have plastic cages and one could have failed. The next step is to pull the seals and take a look.
