Idle Jet #38

Idle Jet #38
This jet will fit either the GY6 carb or the QMB139 carb. It is a little longer than most GY6 idle jets making it's performance outstanding as it reaches further into the float bowl. For most cases this is too large a jet for the 50cc QMB139. This is usually the perfect jet for a 150cc with high flow air filter and performance exhaust pipe.
