I'm having trouble with my '46, 216, with a carter w-1 carb. It's hard to start unless it's already hot or warm. I put a vacuum gauge on it and it reads normal. When I screw in the idle adjustment needle all the way the engine doesn't die, it does stumble a bit but doesn't die like I'd expect. It'll start cold sometimes when I prime the carb with a little chainsaw gas. Also, I can't get it to idle down. I don't think there's a vacuum leak. Any help or suggestions appreciated. Jacques
