Tuning and jet selection
Carburetor jets control how much fuel enters the air stream at a given throttle position. The primary jet is the main part of that control, so its size affects mixture across much of the driving range. Jets come in many stamp sizes, and choosing one is usually done after checking the rest of the fuel and air system rather than by guesswork.
A jet is usually replaced with a new one of the same or a tested size rather than changed in small steps. Clean the jet and its passages before installing it, since debris can alter flow more than a small size change. After installation, check spark plugs and idle quality for signs of a rich or lean condition, and adjust only in small steps.
- Clean passages before fitting
- Note the stamp size you removed
- Check plugs after a tuning change
