ran buggy for 8 min practice at track and tweeked the hsn to get better top end as was no power at third to full throttle, this was ok power wise after adjustment .
ran next quals for 6 mins and checked the temp as soon as i stopped and it was 120 deg, car had very erratic tic over where when throttle released engine would run high for 5 secs then drop low and stall, any idea what i did wrong? had to turn hsn about 1 turn in.
track temp was about 4 deg and damp.
ran 15 min final and got 8 min tank, temp after final was 150 deg

thanks kevin
