Title: Main Jet Measurements
Post by: Kenho21 on July 27, 2011, 02:56:51 AM

Does anyone have any idea as to what the numbers on main jets for 139qmb carbs correlate with? Is it millimeters, so #85 would be .85mm and so on? Whats the deal folks?

yes that is correct a 105 jet = 1.05mm whereas an 85 jet = 0.85mm as you said
