I am working on a full restore on this engine. I have replaced all magneto parts, plugs, wires, carb kit, cut-out switches, leaf plate, and all wiring. As far as I can tell I've replaced anything that could fail other than pistons. It will start up but I am getting a distinct pop on the bottom cylinder. When I pull the bottom plug wire its running smooth but when I pull the top it sputters, pops and stalls.
My instinct is that its probably timing but I wonder if there is anything I havent thought of. I know i dont have the carb completely dialed in but I cant imagine why that would affect only one cylinder. Possibly carbon build up?
Thanks in advance.
