You know, now your just plain ignorant. I called the engine lean beacuse of the glowplug color, and i know i am right after 15 years of running nitro engines, and i have been tuning them for quite some time with good results. I was also the importer of the Falcon enigines to Norway witch was the same as GRP engines so i have had quite a few between my hands.

The detonation can also come from to high compression, but the plug would look different, the filament of the plug would have been pushed in, so high compression is not the case here.

Maximo is an incredible tuner, with an awsome reputation!

Werks, well, that is Werks Racing who makes Werks engines and fuel.

I am 10000% sure, that if you buy a new engine, put on the old carb after running in, you would do exatly the same with your new engine.

If you got sick, theese doctors would probebly do more for you than alot of the doctors that is just idiots with my hart condition....
