So at the race this weekend, went thru tech with my GP, everything went perfect as planned. Tach checked at 3540 where I had it set at. Got out on to the track and it was wet, ran really poorly, so I went down gears. Second heat race ran equally as poorly. I was able to watch my tach the entire race, 2950. Got back to the pits, put the clutch in grabbed a handful of throttle, 3540!!! What could cause the mower to bog down so much??? I never once got close to running a governed speed, but it rolled around like I was just out on a Sunday stroll thru the park! Any ideas much welcomed!
