Re: Engine Troubles...
A good tuneup would be the first thing to do. This way you know what's been done. I never like to take someone else's word for it. Get new wires if they look old or are original, new high quality points (not cheap ones), cap and rotor. Adjust the points to specs and as mentioned up the idle a tad.
The vacuum can be checked on any vacuum port on manifold vacuum (lower part of carb or manifold itself). Maximum vacuum is best. I like to see my engines (minus radical cams) between 17-22 on a vacuum gauge at recommended idle rpms. I adjust idle air screws on carb, idle rpms and timing for maximum vacuum.
