I got the potentiometer to work. Tried installing it according to procedure , install at max ohm, pin, etc. But the pot doesn't have a stop, not sure if its supposed to. It will keep spinning in either direction.... After trying about 6 or 7 different times I finally got it to work for both forward and reverse. my pot sweeps are at 1.9k ohms at neutral,.4 ohm in forward and.3ohm in reverse... This is wrong according to manual. Manual states in neutral it should read 4300 to 4600 ohms. Machine is still extremely slow. less than a creep... charging now to see if anything changes..
