this engines runs so cool at such high preformance, anywhere from 180-220 is the standard i am getting depending how lean i get it.

you would be amazed at the speed it has at those low temps.

so it's not a heat issue.

i thought maybe i was bumbing flywheel till i it on flat ground testing it and got the same issue.

it is much worse when cold but continues at heated temps as well.

i have not flushed the carb? please explain that to me.
thanks.
