Another useful item I've fabbed up is a timing advance for my Briggs motors. I have used offset keys before and they work okay but offer no adjustability. So I found that there's a place on the block under the flywheel to mount a pivot and attach the coil to. Here's the pieces I made up. I mounted a lever to the fuel tank to move the mag, but a handlebar lever would work fine also.
This is the assembly ready to put on the motor.
This particular 5hp Briggs has an 8hp flywheel adapted to it with a chrome cover i added.
Retard for easier starting and advance on the fly for some more rpms.
