Seriously speaking, I am curious as to what happens if you put gasoline in a nitro engine? Is gasoline more combustible? What if you added a bit to bitro fuel?

There is no need for dumbass remarks here.

Normal gas wouldnt run in a nitro engine so dont even think about it.

So gasoline wouldn't even combust in a nitro engine?

It's the same as putting gas into a diesel engine. These small nitro engines operate on the same principle as diesel engines. There has been diesel head conversions for some airplane engines, but gasoline will not work.

No it won't. Nitro fuel is a glow fuel, thats why you use glow plugs. Gasoline is a "spark ignition" fuel and thats why you use spark plugs.

Ahhh, I see now.

What other types of additives can you put into the feul as to get more power...without caring abuot reliability.

Just curious to experiment with an old engine.

Add more nitro, use the correct glow plug(in reference to the nitro content and engine compression). Or just change the clutch belt, get a 15T or 14T but the acceleration will be slower.

'gasoline', or petrol as we Brits call it, won't work because glow engines rely on a completely different principal than petrol engines (as had been said). Not to mention the fact that standard full-size car fuel from the station will be neat fuel, no oil mixed in so even if you could get the engine to start (which it won't of course), then you'd trash it within seconds.
If you're trying to economise on fuel (I suspect you are), then mix up your own. Methanol and castor oil are the base ingredients then source some nitromethane and you're in buisness!

Yeah, w/out the castor in it, it would burn up real quick[:@]... just like in other 2 stroke engines where you have a fuel-oil mixture, the fuel acts to both combust and lubricate...
