Pete thanks for the reply and I am planning to contact the shop that I had the work done on Mon. I guess my question should have been is there anyone out there in 300 land that knows about the holley 4160? I don't think where the leak is it would had anything done to it.It looks like I might have a very small hole/crack in the housing of the second fuel bowl. Any info. on if this type of part can be ordered or if I need to get a new carb. ? Or even if I can repair it Chris 69 300
