Always start rich and lean the jet until maximum performance is reached. Never run leaner than the maximum performance jet size. The maximum performance jet size will vary with weather conditions. If two jet sizes run the same, always revert to the richer jet.

SRS Engines Hybrid Float-Twin Pump Carb System

Superior Fuel Delivery Unveiled The All New SRS Engines Hybrid Float-Twin Pump Carb System Testing is complete and the results are exceptional. Relative to the twin pump fuel re-circulating systems traditionally used today in SKUSA stock CR125 shifter karts, the new SRS Engines Hybrid Float-Twin Pump Re-circulating System performs better in every track test and dyno test we ran. On the dyno the new SRS Hybrid system with the stock Keihin PWM38 carburetor showed a horsepower increase of 0.5 between 11000 and 12000 rpm with no negative side effects through the power range. The increase comes from refined control of the fuel mixture (i.e. the richness or leanness relative to rpm). In the former twin pump systems, the main jet and pilot jet could be used to alter the mixture curve to gain more performance in parts of the rpm range but not all. The SRS Hybrid system utilizes the stock float assembly to limit the fuel level in the float bowl to achieve the optimal fuel mixture throughout the power band.
