Some adjustments on the carb and timing. With some low RPM pulls, not under full load to check Air/ Fuel ratios and EGTs.

Some more fine tuning on the carb and timing to dial in the best timing and jet settings. Did some full load pulls. We achived our goal of 12.6 to 12.8 Air/Fuel Ratio and 1270 to 1290 EGTs. Now it's time to add the BOTTLE!!!!

BOTTLE TIME!!!!
