« on: March 16, 2015, 05:44:31 PM »
I build alot of 5 hp briggs racing engine back in the day. This will be my first honda build.  Anyone know the stock ignition timing?  I like to get as much out my engine as i can. Hope thats is not a stupid question.
Thanks in advance.

I thought it was just a key. Are you running billet flywheel or the stock one?

Turn it all the way negative is stock timing. I started with that. Got my engine to wear in then put it to 3 part after stock.
