Heya..
I purchased a novarossi cx12 new,
run it in as directed from the shop... And am on the 12th tank of fuel..
The motor i cannot stop running very hot. I have no temp gun, but a quick spit test is insane, the heat dries it instantly :/
I have main needle screwed 5 1/2 turns out, low speed 2 1/2 from flush with carb, at these mixutes, the car runs, ok, dies on instant full throtle, but slowly acclerates to top speed fine.
Lean the mixtue in to try increase take off, and one hit up the straight and back, spit test the motor and ack! hot as :/.
Ive leaned both in as far as another 1/2 turn in, before im to scared it'll cook, but leaves accelaration really poor.
Ive tried angled air filters so the head has much better air cooling, limiting carb opening at full throtle, and 15/20% nitro with no luck :/ Its runnning a fox plug as well.
Any ideas anyone ?
