That is what I was thinking, as the engine never has a chance to cool down properly on the low side. I think this raises the head temperature slowly above what you see in a 10 minute race and sooner or later you just rev way too high for control when you get off the gas. I am going to seal the engine and then go from there. Two other quick questions though:
1. Do I have to seal everything in that article on the GoTechs? Ie, backplate, carb, carb clamp screw, HSN, etc?
2. If you end up richening up the LSN to get the mix right at the end of the race, do you guys have any issues keeping it running at the very beginning when the engine is cold? Ie do you have to constantly rev it to blow out the extra fuel until you warm up the engine?
