I just recently put a Wieand Stealth and an Edelbrock 4bbl on my 65. I had some old gas in the tank and thought that was the prob. so I drained that and purged the fuel line. I also replaced the plugs, but the thing still won't start. If I spray ether down the intake it will start, but it won't idle. I think the carb is properly installed and I can't think of anything else I could check. The timing marks were lined up so I don't think that is it. Does anyone have any ideas?
