So timing I have no idea don't have a way to tell, just turned it to a good running position and ran w it,took off the Lil black cap on the carb on the side of the bowl..had no affect, but the stutter when I barely press the throttle is gone..keep in mind it's cold enough to snow so that may have some affect, now my biggest problem..I think is the transmission, it's screaming at like 5k and I'm going 20 I added fluid, helped a Lil but can't even spin the tires...on ice..I've played with fuel and put 93 in, little more response but it still acts like there's a traction control on the engine, you have to slowly build speed no full throttle. Idk if it's the transmission or engine at this point
