Have you checked if the plug you're using is still good? I had that happen once or twice and after a change of plug, the problem went away.

Dude, you are overheating your motor! Try to keep the temperature in the 110C range.

adamkerrnz

what % nitro are you using? what % oil. could be the oil in your fuel. cut the drivers side window out of your body, give it more air to breathe...

jeffery, he isnt overheating his motor. the GS15R has been known to run in excess of 300F just to make enough power

No kidding?!?! Wow I've killed a couple of Nova based engines running at that temperature.

I am using blue thunder 10%. Don know whether it is due to the fuel I am using right now.

Check and make sure you have no leaks in the fuel/pressure line.

I think you better check the glow plug type that u're using, and retune your engine, it just needs a little tuning it sounds like lean. also check for air leak especially in the primer. better to remove it...

I have a friend who`s also running a GS15 and its regularly above the 300 deg f mark.........even when running super-rich and no body on the car its on the 300 deg mark......must just be inherent to this engine.
Having said that though, his engine is super- reliable......I`ve never seen it flame-out and starts very consistently.

I have 2 novarossi engines that run right at 300. haven't hurt them yet, but i don't recomend it either.

Could you just replace the heatsink with bigger ones ?

With stock engine, I don't think so much about overheating.... infact I might do some crazy experiments to get the most power. Maybe over 30% nitro, drilling the carburator inlet to make it bigger diameter, widening the sleeve's ports.

Definetely you need bigger heatsink to make it last.
