Thinks about it Ron the tune-up specs mention a mph equivalent to test or increased engine speed if you are on your own a way to increase it while testing is to use the hand throttle for a constant increase in engine speed to test conditions under load. Oh and a P.S. I didn't write the directions I just own a copy.
it has nothing to do with a tach. throttle may let you set the rpm to a certain position is all that it will do( which was generally done by ea)r.
throttle was mainly designed to raise idle after starting, so that you could open the choke aways to maintain it running, so that it wouldn't choke itself out. also to raise rpm for pto drive
"is to use the hand throttle for a constant increase in engine speed to test conditions under load". why wouldn't you just use the foot throttle as it would be under load?
