Jet Testing

To determine if you have the correct jets in your carburetor, operate your vehicle for 20 minutes at sustained speeds.  Stop and pull a plug. Gray - Good, Black - move down one jet size, White - move up one jet size. Do it all over again until you get a gray plug.

This assumes your engine and electrical system is in good running order.
