Hello I have new project and need some help. Im trying to use what I got and can't figure some things out. First is I have a old Yamaha Chappy frame. I gotta get a set of forks and rear shocks, but the issue is power. My two engines are a 3 hp briggs off a edger. It has no governor. Intake is 3/4 and bolt holes are 1-3/8 inch center to center. I also have a 5 hp off a wizard tiller but its governored. Same hole specs except it has a 3rd hole a little further over. 2. I plan on using a vm20 but Im having trouble finding a intake manifold that will work. I looked at the ET 407 but is $50 and unsure if it will bolt up. Ive read Tecumseh work but no one mentions what part numbers. 3. Id rather the 3 hp but if I use the 5 hp what should I do with the governor?
I appreciate

I build a sleeper briggs a while back. It's all raptor inside. It rips.
Raptor parts used to be plentiful on ebay. Not so much any more.
That looks sweet! I really like the old briggs look. I gotta find a frame though. Found a crankshaft on ebay for $45 with a longer shaft. Im gonna check the rings as well.
