Status: online 		The only thing that happens is that the timing is advanced. If you go up in Nitro by that much though, you should be adding a head shim. Sometimes that is not enough to compensate, so then also going to a colder plug usually corrects the timing enough if just adding a shim didn't.

What you can experience by advancing the timing too far is detonation. That is where the fuel inside the chamber burns much too soon - well before the piston hits TDC (Top Dead Center). This will cause all kinds of stress on the conrod and other internals.

Status: offline 		What RCtruckRacer is right and also instead of adding a shim you can get a colder glow plug. It should do the job cause .18 engines can handle more nitro percentange than .12 and .15 ones.
