I have a new Holley 600 (4brl Street Warrior) on my 66 Mustang 289. The carby is new, but wasn't put on car until recently and the warranty has expired. On starting the car it ran roughly for a short time then stopped and a fountain of fuel continued to spurt out the front fuel bowl vent. I stopped, of course, fearing a fire.

Owing to the difficulty finding anyone these days who knows anything about carburetors, I'm hoping someone can tell me what might cause this problem It was...
