I didn't mean to quote mysel!
I also forgot to mention that i bought the hub set on Amazon

My metal pieces came in today and I want to make a mount similar to yours. Could you please let us know how you mounted the engine to the 3/8 plate? Did you countersink the bolt heads or make holes in the angle? Any pics of the bottom of your mount. Appreciate you taking the time to answer our questions. Thanks

Nice build. I am just finishing up a 79cc Cranbrook, have a few details to complete before tearing it back down for paint. I will post some pictures when I get off work.

Also, what size is your sprocket hub adapter? I wanted to order one but I’m not sure what size Huffy bikes use. Thanks

Huffy cranbrook hubs take the 1.5 adapter

That is way mine turned, hub is 1.500 and the manic mechanic adapter is 1.528 which requires me to wrap a shim around hub

I think you are still better off replacing the Cranbrook hubs they are low quality to begin with and putting horsepower to them they will fail, I have already had trouble with the bearing cones loosening up.

I really like your brake set up. I am running a torque converter so I would have to get a longer shaft and run it on the other side of the frame. I am interested in how well yours works?

Instead of adding a sleeve to the hub, sand/mill some of the facing off each side of it to make up the difference that way you won't have two extra surfaces to worry about slipping.

I had a similar issue with my Hyper frame...rear adapter started slipping and the ends were pushing against the spokes. When I took it apart I measured it just to be curious and the hub was like .015 thinner than the closed adapter was so I sanded down half of the difference on each side to get it just under hub thickness. Cleaned the outside of the hub and inside of adapter with iso to make sure it didn't have any grease residue and it worked great after that, no more slipping. With the Fairmont I built it was almost perfect so I didn't have to touch it, but on a Roadmaster mountain bike I had to do the same thing with the 1" adapter...mic each one then adjust as needed. Now I check every hub that I plan to use an adapter on before installing.
