Been doing some small projects on the 50, front mount, 6v these past few weeks. Haven't used it all that much or worked it hard at all.
I've been noticing that the engine will throttle up nicely to about 3/4, but struggles and stumbles at anything past that. I cannot get it to WOT. My carb is adjusted correctly and runs really sweet until 3/4 throttle.
What I see is that once it hits about 3/4, the governor will push the throttle plate toward the wide open position even though the dash throttle lever has not moved. When I bought the tractor the tab for the governor spring was broken on the linkage arm and the spring was held on by some tie wire; i did not touch it.
My question is how much, if any, spring tension should there be at idle and the governor in the "home" position? I will be checking the electrical and putting in new/cleaning the points before it gets too cold. Plugs are AL 437, new less than 20 hours on them.
