Hi! I have another question...
Hi! I have another question about my 67 Thunderbird,I had to install a new carburetor on my car,The mechanic said it was beyond repair,I had a new fuel filter,points,condenser,timing set,carburetor adjusted yet it still hesitates slightlyfrom a stop light and surges between 45 and 50 mph-The mechanic said it could be in the transmission and since I have a new fuel pump,fuel lines and fuel tank ,he is not sure what is causing hesitation? It also has a new coil ,I am not sure what is going on,Why would it be surging or bucking at certain speeds?
JA: When did you last fill the tank? And do you smell gasoline around the engine?
Customer: Today
JA: Are you fixing your Thunderbird yourself? What have you tried so far?
Customer: No smell
JA: Anything else you want the mechanic to know before I connect you?
Customer: No a restoration shop

Check for a vacuum leak and also check the distributor vacuum advance.

To check for a vacuum leak, with the engine warm, choke open, at idle tag a rag and shut off all the air going into the carburetor by holding the rag tightly on top of the carb. The engine should stall, if it continues to run then it must be getting air from somewhere and that means it has a vacuum leak.

To test the vacuum advance, the easiest way is to remove the vacuum hoe from the intake manifold or carb, light up a cigarette and blow smoke into the hose for the vacuum advance. It smoke pours out the distributor cap, then that vacuum advance diaphragm is busted and that is the reason for the hesitation and the vacuum leak could be causing the surging.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
