Stupid Distributor Questions

If your plugs look like you put them in yesterday (no color on the insulator) you may be running too hot a heat range. I would go at least two ranges cooler which will help your detonation and mixture. The current gas we have now, plus the more powerful ignition can tolerate a much cooler plug.

At idle you should have NO vacuum at the advance if connected per the factory TSM. You should be connected to the timed (passenger side) vacuum port on the carb. If you have vacuum at idle from this port, your throttle plates are too far open to accurately set the idle mixture.
