I found a Kid's bike today and took the crank off only to discover it is a smaller diameter so the bearings, etc. are too small. I did some more looking in my stuff and found a crank with extra short arms from a 24" ladies Hawthorne or JC Higgins, can't remember now which it was, but it now lives on in an elevated new life as a Worksman cruiser crank. The pull start kit, smaller rear engine mount and front mount shim arrived today from Pirate Cycle (thank you, Justin!) and the mounts are perfect. The front one compresses a bit when cinched down and will be very secure. The pedals clear the bottom of the engine so the pull start kit won't change anything in that regard... just adds a bit of width to the engine. I didn't attach the rear of the SBP pipe to the frame, but can see that it is not going to be a problem and the pipe does not interfere with the front sidecar mount. Big relief in trying to cram a lot of things into a small area. I do have one obvious problem, however. The engine fits the frame so tightly that there isn't room for the throttle cable to fit into the carburetor without running into the frame straight bar directly above it without cocking the air cleaner off level. No good as I think it would lead to float problems as well as look wrong. I recall that others have had this problem with builds with tight frames and don't recall now what the solutions were. I'm thinking someone might sell an offset intake manifold to solve this very problem. Seems to me someone does, but can't remember who. I'll start with Pirate and SBP and go from there. If one of you knows of a solution, please advise...
I'm glad I did the raw installation (no gaskets, washers, etc.) to fit things. The frame paint has suffered badly from on and off, on and off, move it up a bit, no move it down. It is inevitable that you are going to scratch the frame unless it is a plug and play bike, so this way I can minimize the damage when I do the installation after repainting.
Tomorrow I'll drill and tap holes for the head badge and then dismantle the bike. Getting closer...
