Re: timing advance how much is to much
Most engines will run "Alright" when the timing is off and the AF readings alittle rich. Unfortunately, most people accept this if the car does what it's supposed to. I consider myself quite capable of tuning my engines better than that. No so ol great one. I had a problem with the 2GC carb on the 280, so i rebuilt it with a new kit with a set of jets an accelerator pump from Daytona carb. My surprise is, it never ran this good before. I think the problem was, i spent too much time on the ignition advance i neglected the AF. Both are very important. i might addd an engine running rick will wear out the rings quicker. I think tha's what was wrong with the280.
