I have a 180 (same ignition module) and called Terry at C&H the other day...about a CH auto advance for it...

He dosen't know if their unit will work with this motor...without having to machiene up a new prop adapter with their magnet and pickup...
He really dosen't know if the pickup in the back of the motor is a Hall efect type...was thinking of sending him mine and letting him find out...

I also have 4 motors with their ignitions....not a failure yet..

If you do anything please let me know...
