I have a Jonway/Roketa MC-54-250 with the CF Helix Motor I just broke 7500 miles on her.
In the mornings or anytime the engine is cold I have to sit there and rev my throttle till she warms up or she will stall out on me, this has never happened before.
Can anyone point me in the right direction to fix this problem.

Thanks
