If high nitro as set really rich yes. Alcohol and nitro will not cool the air as much as gas so carb heat would not be needed. Also the fuel has a wide latitude for mixture especially with high nitro percentages.
That said I doubt anybody with enough knowledge to operate a glow engine would be stupid enough to do this. Most of these people are using electric motors, no knowledge needed.
