help with a stalling problem.
128, K301A.
i have a very annoying stalling problem i have been chasing. during the chase i learned everything that could cause a stall, was.
i replaced the coil, spark plug wire, spark plug, points, condenser, air filter, carb, linkage from carb to gov( new carb requires it),fuel line.
added non cadet inline fuel filter.
adjusted carb and gov linkage.
engine was removed dissembled and inspected. valves reseated, all gaskets replaced.
mouse nest removed from blower housing.
clutch replaced, all of it, shaft, plates, springs.
oil changed.
RPM 1200 -3200
creeper needs work, slips out of hi.
it still stalls. it is a slow stall, like an overload stall. when you cut grass too tall.
it cuts grass 4' tall with out a problem.
i believe it is a governor problem, but no matter how i adjust it, it either gets a lot worse, or a little better. meaning, i can get it to run longer before a stall and i can run all day at half throttle.
i am wondering if i am missing something.
can someone watch the videos of this tractor that i posted on youtube and tell me if they see where i went wrong?
is it possible it is internal? should i disassemble the governor gears?

this shows how i have the linkage set up. the throttle clamp screw is not cadet, that one broke and is on order.

stall. it sounds like i slowly lower the throttle, but that is not me. this is how it dies, slowly.
like it is overloaded, but if you disengage mower, it still stalls.
thanks for any help anyone can give me.
