I recently had the carbs cleaned. In the process, a fuel jet was replaced (cracked). Before the cleaning and repair, the engine would not idle & bogg down at high rpm. The motor can be running at 4000 rpm's, then rev up to a higher rpm like flipping a switch, then back down. Seems like it is not running on all cylinders. Spark tested all four plugs..ok there. Extremely slow accelerations...if you try to get on plane quickly, the engine boggs down....<br /><br />any ideas?
