OK heres one for you, DA 100, starts fine but will not power up to full throttle. Pulled both plugs and flipped checked to see if I was getting spark. Initially only the rt pluged fired. I then swapped plug positions and flipped checked and both plugs had spark.

Went back out to the field this weekend and the same thing happend. engine starts but will not advance and lacks power.

I temped the heads with my Rayteck and the left cyl is at 100- and the rt is at 140..... at Idle.....

Do I have preliminary IGN failure.....?????
