Is it the carburetor or an electrical problem?
When my 1970 IIA idles, the battery light comes on and the amp meter goes negative. Reving the engine solves the problem temporarily. I tried adjusting the idle speed on the carburetor and that made things a little better - the amp. meter now hovers closer to zero but still a little negative. Should I just keep increasing the idle speed or does this indicate an electrical problem? I replaced the generator about 2 years ago.
