Can anyone tell me what the factory carb settings are for Nova Mega SX 21 EV5 MS Engine. I can't find any specs to download and I am new to nitro. This is on a Serpent 950.
Thanks!

A good starting point on MOST Nova based .21's is:

5 1/2 turns out on the low speed needle and 3- 3 1/2 turns out on the high end needle.

Thanks for the tip. That is exactly what I needed is a starting point. I am assuming that 220 F is a safe operating temp.

Set it just as you said. It worked great. The temp was 166. It was a little fat. I tweaked it about half on high and low and it cleaned up with a temp at about 196. I am always open to recommendations.

leave it there till you get it on the track. the driveway isn't quite the same as the track. you're looking at a good starting point though.

220F would be safe for that engine.
