Ive had this poor little 1976 3hp B&S for many years. It was headed for the scrap heap. I rescued it when I was in the small engine business as a parts source. I thought it was cute and tucked it away. Turns out only the points need cleaning. Its a reasonably uncommon configuration with the updraft carb, which is very compact, just perfect for stuffing into a bike. I wound up with a Schwinn Delmar trade. The frame configuration is great. With a single top tube its wide open for bigger engines. The frame is also wide for larger tires/wheels. So this is whats going on. This is really I guess a light motorcycle as the reduction will run through the bottom bracket. Ga does not require pedals so I guess I don't either. The drive will be to a Nexus 3speed IGH driven on the right side. I have been beating a Nexus with a 49cc 2stroke and it hasn't failed yet. I think with careful handling of the Briggs I can make it last if not I will find an SA IGH. I'm really tickled about the way I did the bottom bracket. Normally I make discs to hold 5/8 bearings and weld them to the BB. What a PITA! This was a five minute bolt on and it clamps so well I couldn't budge it hitting the shaft with my copper hammer. Will be running 26x2.4 Cyclops tires on 50mm rims. Has a new Cruzer(don't say Whizzer!) 8qt gas tank. One of the nicest tanks I seen from China. This is where it is now. I'm in and out of town so it will progress slowly.
