Carburetor Tuning 201

If you notice that you are one point off the A/F ratio you want (12.5:1 instead of 13.5:1), step down four jet sizes. A good rule of thumb is that by going up four jet sizes will drop your A/F ratio one point and going down four sizes will raise it one point. Shoot for 13.6:1 on the primary jets and 12.5:1 or so on the secondaries to keep the engine from predetonating. This is the primary metering block, and the power valve is situated right between the two primary jets. View Related Article
