Can anybody get a good Spark plug reading using Ca. Gas? I was told by MPD that it was not possible. So I was thinking of gettin a little AV Gas to do the final tuning in the carbs?? Whatcha Think?
If that were true then the guys running alcohol would be lost. Read plugs like you would on an alcohol engine, check the heat tracks [discoloration] on the plug threads, usually 2 to 3 threads. Check the heat bluing on the ground electrode and always check for signs of detonation on the porcelin [sp]
Hey FoMoCo, Racing Ray had a good post on this subject here: http://free.***boat.net/ubb/Forum4/HTML/001953.html
