Heres my problem, when I try to accelerate quickly and I mean pedal to the floor as quickly as possible the engine will almost die like it is either getting to much fuel or not enough. I did notice today that my electric choke is fully open all of the time and if I would hold the choke about half way closed and then accelerate quickly the engine seemed accelerate much smoother and didnt quite act like it wanted to die. I live in lafayette and if anyone lives in the city and is familiar with carburetors I beg you please help me out. I have a hard time explaing the problem so it would be easier for someone to actually hear it. I think I possibly may have to re=jet the carb but I am really just guessing at this point.

Thanks in advance

It sounds like a jet issue which has been known to be an issue on some webers. Shipped with the wrong jets. Paul tracked down some good info a short time ago on them while running into the same issue. I'm sure you checked but do you have good fuel pressure from the fuel pump? Old factory mechanical pump could have a leaking diaphragm. I think I still have one off my 67 if you need it. We have our monthly meeting at Buffalo Wild Wings this Sunday 1 - 3 p.m. it would be a good time to come out and say hello. If I'm able I'd be happy to take a ride over and look at it for you.


Some good info.
