What is a good clutch for Briggs, 2 or 3 disc? I'm thinking 2 disk would be lighter and be good for a stock engine, and 3 disk would be required for a higher hp engine.
You could even get by with a single disc for stock class racing -- as long as you don't have a lot of restarts.
2 disc Bully is the standard "go to" clutch for flatheads.
Yes, 3 disc for highly modified engines.
