Note being a conversion kit every engine will react differently depending on wear, other components and their condition, maintenance history, timing etc. Some tuning and adjustment maybe needed. 
We recommend the OEM carb as our first recommendation as they seem to be tuned closer right out of the box most times. Run hi test and ethanol free gas if available. Also we recommended putting these kits on freshly tuned up and timed engines with valves adjusted for taking advantage of these carburetors potential, we sell full master tun up kits on this site for more info on the Master Tune And Service Kit Click HERE
 
WE Also Highly recommend Our High Quality Modern Pulse Pump Conversion Kit that we also made for a easy and reliable install with A top quality OEM supplier pump, custom adapter plate, designed and made here in the USA and clamps and hoses for complete kit and install.
