the left side of the engine has weak spark ill pull the wires on the right side while running and the engine almost dies i do the same on the left side and not much rpm change. starts and idles fine just loss of power and a little hesitation on acceleration i rebuilt the carbs but they were clean checked the fuel pump looked fine. i tried squirting fuel in while running in each cylinder and it bogged. i get on the throttle and see fuel coming through the main jets on all cylinders and im just at a loss please any input here would be great.
