driving habits are the biggest thing when it comes to mileage.
Also condition of tune, plugs and timing, very critical
The carb, meh ... put a well tuned Small quadrajet non electronic carb on it.
Be sure you have a non computer distributor on it.
Your mileage will go up.some.
How many miles was a good question, a good tune cant help an engine with excess blow buy at the rings. To much is lost right there.
Need to do some preliminary checking on the situation. Dont just throw parts at it . Learn how to ID a problem and how to do basic tune up work.
Check it out first.
What kind of distributor does it have? Does the engine smoke?Does it have plenty of power as it is right now?
