I bought this 79 bronco with a 460 in it. If you start it it will shutoff right away if you dont constantly give it a little gas for about 3 to 5 minutes when the temp rises and then you can keep it running without giving it gas. Is there not a way to get it to start up and idle fine right away. The engine only has 51k miles on it. I was told that the cam is very large and oversized or something. They are running a brake booster because the bronco supposidly needed it. I got the dual battery setup and a new alternator and starter. The carb is a holley 4bbl(not sure what size), with a dual or twim fuel line pumper or something. When i had a proflow triangular air filter on it the carb would sometimes shoot out a flame which burned throught the filter. When i put a circular filter on it i havent had any flame problems and recently after retiming it it has been fine although the timin marks go from 0 to 3|0 which i was guessing was 30 cause the marks stopped after that. I have it at 3|0 now and havent had a flame problem. Im not sure how to adjust the idles on the carb because im not fimilar with holley or 4 bbls. i replaced all the battery cables. Is the engine just so big that it needs to warm up or can i fix this.

Does the carb have a electric choke? Sounds like there is no choke, or it is not operating right.
