i have the service manual, I already set it to the specs, but it says I might still have to move the spring, as each engine is a little different.
again, it ran fine until i started hitting heavy grass. not too heavy, but the kind where you hear the idle come up when you hit it, and you might have to shift to 1 low.also, stepping on clutch, does not avoid a stall. normally, if you start to bog down in heavy grass, you stop, and you avoid the stall.
the only thing I did not try is the adjustment of the governor arm, where you loosen the bolt and move the governor arm on the shaft. i didnt want to try that until i was certain i had a governor adjustment problem.
the exhaust leak causing stalling. i do not know why it was stalling, only that when someone on here pointed out the leak in a video i posted they suggested it as a possible cause and it stopped stalling when i patched it. it was leaking at a joint , near the carb, and i used furnace cement.
some suggested the hot exhaust was heating the gas and causing vapor lock, others suggested it was causing loss of back pressure.
