I need to know what the correct timing for a 2.0L (built to 2056) with and electronic ignition, no vacuum advance running dual carbs.
I set the timing to 27 degrees BTDC per the manual but it doesn't run right, it seems much happier with some timing taken out. Any help is greatly appreciated. Thanks in advance. |

I'm running dual Dellorto-40s with Pertronix. Many times I have attempted to set my timing to the "normal" 27 or 28 degrees suggestion, but I always have to reset advance to about 30 degrees for proper running.

Ansbacher I find +/- 2 degrees from the 28 rule is acceptable, but retard it gets doggy midrange and 30 is the max or you start to get too lean at load. If the OP's engine was working fine at 27 before the pertonix install it should also work fine at 27 with the pertronix. |
