imearl49 Posted February 8, 2012 Report Posted February 8, 2012 Does anyone know the factory setting for the needle valve 49 B1C. Any suggestions would be appreciated. Thx Quote
Don Coatney Posted February 8, 2012 Report Posted February 8, 2012 If you are talking about the carburetor idle jet needle valve it must be adjusted to the engine as all engines are not the same. A starting point is 1 and 1/4 turns open. Fine tuning adjustments must be made from there. This is not an engine speed adjustment but a fuel/air mixture adjustment. Quote
B1B Keven Posted February 9, 2012 Report Posted February 9, 2012 Top of the float should be 5/64's ( +/- 1/64 ) below the top of the carb body. That sets your needle and seat adjustment. Quote
