Stepper motor regulation problems

Yes the Triumph starter gear only spins one way with pliers.
I do know to change out the nose of the Toyota starter.
I do suspect a bad TPS.
Thanks for the reply.
I was wrong, Triumph and toyota starter will turn both ways with pliers.
 
do you have a manual or do you go online for info
i can help if you don't have
Thanks, I have a genuine Triumph manual.

Also had to use the Toyota motor backplat
This was exactly my problem! I had to use penetrant and pliers to loosen the idle linkage section on the throttle shaft above the stepper motor. It was stuck and keeping the butterflies from completely closing and also made it impossible to adjust stepper.
