MVVS 4.2 help
 
Just bought a combat gremlin with MVVS 4.2(I think it's.26 ci). Need help with fuel type and carb settings... anybody?

I would go with a low nitro percentage glow fuel at first, say 5%. Do not use model car fuel as it doesn't have enough oil it in. You need something with at least 16% oil in it.
Leave the low speed jet adjustment alone, it should be already set Ok, just screw in the main needle until it stops, do not force it, be gentle. Then unscrew it about 4 to 5 turns and use that to get the engine started, then the engine will be running rich, but it is easy to lean out from there.

Thanks Earlwb. Hopefully I'll get to try it this week.
