Had a beautiful day today to finally cut my grass after way too long and ran into a snag. Seems like my engine doesn't have any power under load.
After start up, the engine seems to slowly rev up to a nice, smooth operating state but when load is applied, e.g. going up a hill or turning on the mower deck PTO, it bogs down, loses power and begins to backfire.
The start up bothers me, too. That slow rise to the normal operating speed. Seems to me that it would jump right up there before.
I removed the air cleaner assembly to watch the carb linkage movement as a load was applied. When I switch on the PTO, the governor linkage pulls back, I can see more fuel coming into the carb, the engine begins to bog down. When I turn off the PTO, the governor linkage begins to return to its previous position but not quite; engine begins to run smoother but still not that nice crisp sound. A second or two later, the linkage nudges just a bit further forward, almost to the positive stop, and then that crisp, smooth firing begins.
I've recently replaced the points and it was running great last time I used it.
Any ideas where to start on this problem?
