Hi guys,
I'm running a standard 350 with carby. While driving, I have a surging between about 13000 and 1700 rpm on both unleaded and LPG.
I'm pretty sure it's vacuum related.

If I post the engine number, is it possible to tell what model and year I'm dealing with?
I may then need a vacuum diagram to help chase down the problem.

Thanks in advance.

Thanks for the replies.....

I have a Rochester carby, would this 1970-80 engine/carb combination all have the same vacuum system?

Any suggestions for locating a diagram?
