One of the benefits of owning your own machine shop...After researching various internet blogs and chatting with Club members, I decided to lighten the flywheel. (Which means I'll need to balance the crank as well) I was able to lighten the flywheel by 22 pounds from 65 to 43 total weight. I'm told this will add to the engine response time off the line but not hinder the hill climbing. We'll see.
After machining, a new starter ring was installed by heating the ring and chilling the flywheel. It worked like a charm. The photos above show where material was removed from flywheel. Basically 14 pounds was removed from the outside diameter and 8 pounds was removed from the i.d. I probably could have done more but I was leery of reducing wall thickness too much.
Here's a list of the engine and drive train changes I've decided to make:
- 6.5:1 High compression head (Brumfield?)
- reground cam shaft to Model B standards
- lighten flywheel
- balance flywheel and crank shaft as an assembly
- install 3.27:1 ring and pinon in rear end
- machine block by installing new valve seats (intake and exhaust)
- install modern valve set
- aluminum timing gear with new steel gear on crankshaft
I'll keep the Zeneth carb for now with the option to change to a Weber at a later date, based on performance. (Gotta save some money somewhere!)
