few 1970 olds 98 issues

1. when you first give the car a little gas it wants to stall but if i just put the pedel to the floor it does fine also i have no issues with it wanting to stall while driving only when i start to accellerate..

2. ever since i bought the car when ever you turn the headlights on or the dome lights are on they just flicker..i wasnt to worried about it at first but its just getting worse and worse..ive changed the alt. and put an optama yellow top in it, so i was wondering if it may toped working be the voltage regutator?


3. also my gas gauge has stoped working and only moves between full and 3/4 of a tank..sending unit?

Number one is usually a carb issue assuming no vacuum leaks, high test fuel, proper tune up specs. 2 could be the regulator, a voltmeter should be used to check alt output, 3 disconnect the gae wire at the tank look at the gage, then ground that wire, if the gage reads full then empty the dash gage is good. You should have a shop manual if you want to be able to properly work on this.

thanks for the help, i got 1 and 2 fixed..it ended up being a bad voltage regulator and what looked like a fuel filter from 1970 and some old gas..still working on number3
