I had to replace the leaking fuel pump this spring. Then when I started mowing after about 20 minutes, it would die. Ended up being debris in the carburetor.
While I was at it, I put the tack on it to see how it was running
when mowing. 3600 rpm not mowing. When I’d start mowing and hit some heavy grass, it would drop down to around 3100.
I have the service manual for that engine, so I went through and reset the throttle cable, choke and governor. Now it’s like the governor isn’t working I can start it up at idle and as soon as I barely move the throttle it revs up to over 4K. Acts like there’s not even a governor.
I’ve checked and double checked the governor settings, and they’re correct . According,to the service manual, loosen the nut on the governor arm, rotated clockwise as far as it’ll go, which it hits the carburetor and then rotate the shaft clockwise as far as it’ll go, tighten nut.
