Tonight I went out and hooked up my new vacuum gauge to the back of the carb, I was reading about 19.5 inches after the engine came up to temp. I did notice that it would bounce slightly between 19 inches and 19.5 inches. I read somewhere that it should read steady and it if bounced around it could be timing or carb out of adjustment.. Which should I check first?
If I need to adjust the timing what the easiest way to do it with an HEI with out getting bit?
