[Public-List] A4 question

[John Birch]

This kind of problem can be pesky to find the problem, having worked on many 
cars in the old days and having had an A-30 with an A4, the first advice 
most mechanics will be is to start at the beginning.

Suggest starting with a general tune up. Probably you have electronic 
ignition so the tune up is fairly simple. If you have the old make and break 
points condenser etc, tune-up is even more important.

A tune up is never a bad thing and is quite inexpensive. So its a good 
starting point.

Cleaning the carb bowl and carb reservoir screen is always prudent per 
Mike's advice.

There are many things that can cause the kind of problem you are describing, 
so starting at the beginning is a good idea.

Just suggestions

Best of luck

John
