aljken Posted January 8, 2017 Share Posted January 8, 2017 So this happened today.... Flying along, have been for an hour. Engine running well. Recent problems in the last month (all fixed) with the motor include welded exhaust crack (no issues since), pull starter fitted cos last one fell apart (classic polini), resoldered wires for earth (to cut motor) and resoldered CHT wires (wire carries power to the digital display gauge). Also changed bent paramotor mounts (attaches motor to frame). New spark plug recently too. The CHT climbs to 230, (usually its 140 to 180). The red warning light flashes. I come off throttle instantly (now on idle). Temp rises to 330, 660, 880 over a min while on glide, then drops rapidly again to 140 to 180. a little bit more throttle causes displayed temps to jump rapidly again. Then they drop. Engine feels fine to fly, no funny noises, good performance. Do you: Ignore gauge - its wrong probably cos the temps are ridiculous. This happened instantly. Land immediately - requiring 40 min walk back to field with gear. Fly to take off taking it easy on throttle and temps - less than 5 mins flying. I'll post what I did and actual cause when people have had a chance to respond... 1 Quote Link to comment Share on other sites More sharing options...
