I have a 66 inline 6 with an automatic tranny and automatic choke. I switched from stock 1940 carb to an Autolite 1100 and now it wont start. It ran great with old carb until it got warm then would die when you give it gas. Now it won't start at all. Has DBI 2 ignition kit upgrade from custom inlines. The auto light 1100 style with spark assist valve. It has distributor vacuum advance connected to carburetor not intake.timing is correct any thoughts?
