Simple Guide to Jetting

Quick Tips For Small 4-Strokes

 

 

• If it boggs or dies right off from an idle when you turn the throttle, your pilot is too lean.
• Your first main adjustment is your Main Jet. Once you get your plug close with your main jet, fine tune from there.
• When fine tuning your adjustment screws, turn them all the way in, and back out, 1 and a Half Turns, for your starting point.

 

 

 

Before changing any adjustments on your carb,

• Make sure it is perfectly clean,
• Make sure you can see light through all the jets.
• Make sure you have a Clean Air Filter.
