distributor Question

JOB · Aug 19, 2012

I would bet most older tractors have a centrifical advance in their distributors. My question is how do you check them with the engine off? If you gently twisted the rotor shouldn't you feel some spring tension, and how far should you be able to turn that rotor? Or am I way off track?

holding the drive end solid, you should be able to twist rotor in the direction of rotation & feel it move, than spring back when released. they don't move much & all are differant depending on amount of advance required. if spring plate, flyweights working properly, most common problem will be cam frozen to shaft--below rotor, most have felt washer, lube thru here. only way to 'see' it work is running on engine with timing lite, or dist machine. specs probably still out there for degrees advance @ given rpm.

Thanks mite-help, I have a hunch the cam might be stuck after reading your post.
