Some of these carbs, require 6 to 8 pound,s to operate correctly,may need a high out put fuel pump.

Not idling wont stay on, gas is shooting good, when fired up it stood on but sounded ruff, after that hasnt fired up since, did adjustments to the carb already but nothing, engine was sitting for a couple of yrs so new plugs wires, plugs and oil , gas filter

if its the chain it will be really retarded thats why i said to advance it... also take of the cap look at the rotor and turn the engine lower pulley about an inch left the right...if the rotor seem`s to keep up wit it its ok.
