Did you check with Hitch?  He was out a couple of years ago, but may have come now.

I 'm in desperate need of a billet crank gear for my Briggs 33. Just broke our stock one after two years of racing in CP. I know Rocket Ron (rip) had them, anyone else?

I have two cams for sale. One is a Dyno 110 grind. If you need specs you'll need to go to the dyno site to get them as I do not have them.  $60 for that cam.
The other cam is a Don G cam.$50 for that cam
Trannys / Axles / Wheels / Noram star clutch with v belt
« Last post by Mowerpar on May 20, 2017, 04:32:49 PM »
Selling my noram star clutch has been modified with the V belt pulley welded on. Drum is 6 years old with the wear to show. Shoes are three years old. 3100 RPM Springs and needle bearing are two years old, short racing years. Still a very good clutch.  FX hasn't been around and I do not see it ever returning. $115
