What RPM Range are You Running?

Unfortunately the sound on the video is not accurate to what it sounds like in person. The video sounds like it's at idle. At 4k rpms it is screaming in person. I currently have the Tac set at the setting where the spark plug fires 1 time per revolution.

I recently changed the belt to a Carlisle 1042M3 (44-1/8" X 1- 3/16"). I am getting the same results with this belt and the old stretched belt.

Not sure what my next steps should be. Should I try to pry open the primary and secondary? If so, what is the best method to do this?

Why would you need to have the tachometer"set at the setting where the spark plug fires 1 time per revolution"? on a four stroke 20 H.P. Kohler? I hope someone will help me understand.

The plug fires every revolution.

The plug fires every revolution.

Thanks Jim. Can I assume that the tach only counts every other spark?
