heres what i learned and picked up from guys ,, if the fuel system is close on gas , the switch to alk, is at best 10-2 tenth mostly for cooling advantage, and some hp gains,, i have seen 3-4 tenths pick up,
idono carb to carb change you did, no info there given?
i know the guys are told to look at mph, and heat gain in the 1/4 -1/8 mile, if it gets colder down track, its lean,, if it gets warmer by 20 deg its to 'fat' , sometimes diffrent heat rang of plugs are also needed to maximize the effect and burn of alk, timming may also come into play, useually couple * less timming ?
it is alittle diffrent game getting the carb set and fine tunning,
