Don Terrill’s Speed-Talk

I am interested in ordering your, Spark Plug Reading Kit. I need to know if it will apply to alcohol engines as well.

Please advise.

Reading plugs is basically the same no matter what fuel you use. Some fuels make it harder to see the fuel ring, but setting ignition timing and heat range are exatly the same for all fuels.
