Things are moving slowly. I machined a magnesium carburator spigot and mounted one of those aftermarket China Girl carbs with the red cone shaped aircleaner on it. Then I discovered it will have to be mounted at the top of the frame under the Cranbrook little top bars due to excessive length. No biggie, but disappointing except that the exhaust port on the engine mount plate is high enough I can easily mount a 180 degree exhaust pipe with oodles of room over the sprocket I have (4) 6" X 1/4" pipe nipples bent 90 degrees to weld to the frame and bolt to engine plate. I have masking tape on the frame and a 90 degree cross on the crankshaft hole that line up with marks on the frame tapes to locate the position for welding with the plate clamped 2-1/2" from centerline of the frame without having the engine in place. If carb trouble or plug trouble occurs, it means an engine pull but that is only 4 bolts, so, OK I guess.
