After some running/cutting, the PTO kicks out and then back in when driving sideways on an incline, falling right.
It does NOT have those symptoms when driving hill straight up/down, or driving in the other direction (hanging left).

New spark plug.
New air filter.
Clean carb (but not the nozzles).
Could not find an adjustment screw. Is there supposed to be one?
Motor starts every time when spray starter fluid, and runs fine afterwards.
Does NOT start (ever) without starter fluid.
