Ran sled today, ran fine, changed clutch clickers from 3 to 2, then bogged down before 8000 rpms, let off throttle, hit it again bogged down a 7000. Then it seemed like everytime I hit the trottle you could hear the bogging sound. Checked plugs both looked tan. The sled seemed to Idel good just acted like it was starving for fuel, air, or spark with trottle??? Going to set the clutch clickers at 3 again to see if that is the problem, but I would not think so??? HELP going north in 2 weeks.
