Just cant get it tuned right 440

i don't know anything about the carb. get yourself a positive tdc stop, the one that screws into the #1 hole. now turn the motor over buy hand(with all the plugs out, it's easier, lol) until it stops. mark it on the damper under the pointer on the timing cover. turn it over in the opposite direction until it stops. make it again. your tdc is halfway between those marks. now measure to the right 1 3/8" and that is 38 degrees. each 1/16" is 1 degree. you don't need no stinkin timing tape, they just fly off anyway. 2500 rpm isn't too bad, try leaving out the little kit spring and see how that goes.
