The motor will idle fine, but as soon as you give it throttle it bogs, even if you tried to slowly open the throttle. The motor was running fine and all of a sudden started acting up. Maybe has an hour of run time on complete motor build. Motor is a standard bore gx390 with a .100 longer billet rod, .060 shaved flat top piston, stock head with #35 springs, champion 1.1 to 1 rockers, mild torque cam, 6 degree timing key, arc billet flywheel and 24mm bored 3 circuit carb from NR racing. I believe the main jet is a .45.
The motor is actual in a club car golf cart, so it has a pulse fuel pump. I have tried changing the spark plug, putting a different carb on, readjusting the valves, new fuel, new fuel filter, cleaned and blew out the 24mm bored carb and I reset the coil gap to .060. I originally set the gap to .030 and after doing some researching realized I needed to open it up. Non of this made any difference.
Could I have fried the coil and that is my issue? Fuel pump seems to be pumping well, could it be sucking air and I’m not realizing it? These are the only two things I haven’t swapped out. What could my problem be?
