    Cleaning carbon deposits, recommended cleaners

    I've never tried this personally (i.e. don't blame me if it doesn't work). I've heard of people injecting uncooked rice down the intake while the engine is running. Of course these engines don't have catalytic converters. Allen

We began to use CD systems with a pickup years ago, however we would like to revisit using a distributor again if there is any way to keep the caps from cracking.

    Air cooled engines for pump jacks

    Does anybody have any experience using small air-cooled engines (i.e. b&s or kohler) in the 11-20 HP range for pump jacks. I have heard that very frequent oil changes are a concern as well as short life-spans. thank-you Allen Richardson
