ok, the car is running a lot better now! my only problems are the car bogs at the low end. when i open it up its pretty fast but there is still a noticable amount of smoke. and i did the spit test on top of the heat sink and the spit just sat there. i dont wanna over-lean the engine, it seems like i have it pretty lean already. as long as i have it under 270 degrees will it be fine? i only have the high speed open 2 1/4 turns. should i lean the low speed or should i get the high speed right firsT?
