I have a 74 beetle with a 1640 TP and it has a slight flutter at idle along with a small flat spot when you hit the throttle. It is fitted with a 34pict3 carby and has a 009 type distributor. I believe that it should have a vac advance type dizzy. I read some were that this combination I have will give me the problems I am having, I also read the carby mod to fix it, but what my question is does anyone know the correct model carby and the correct model number dizzy that I should have. I am keen to have it idle and accelerate as it should do.
Cheers

I have this information. Cant remember where I got it from, but I have it anyway.

34PICT-3 VW Dist. 043-905-205 or Bosch 0231 170 034

Hope this info is of help to you. I'm sure there'll be others to jump in and impart their knowledge also.

Cheers,

If it ain't broke, fix it till it is!
