You aren't going to believe this, just drove out to where this is stored, put some gas in the carb, stomped the starter got the slow roll and it fired. Ran badly for a bit and flooded out. Battery was low and I am charging it now. This engine has a 6 V alternator if that makes any difference. I am sure there is more to this story than what I have found so far. Has been driving me nuts for years now. Suppose this thread should get bumped to the engine section??
