what kind of temps are you getting on it?if its running hot for no apparent reason then i would say that u deffinetely have an air leak,...............and why on earth did you post this so many times on other peoples threads? when u have a question and you can't find an answer by using the search tool dont just jack someone elses thread!

If you suspect you have an air leak I suggest you replace your fuel lines first or cut 1/4 inch off of each of the ends if they are long enough. The ends will wear out over time.


I have had this problem in the past and sometimes replacing the fuel lines fixes the problem.

If this does not work I will make a few more suggestions but they are for more advanced R/C dudes and require some more work on the carb or inspection of the engine.

I would seal the engine just to prevent future air leaks there. The seal on the tank can be adjusted also by tightening down the screw under lid. I replace my fuel lines often on my trucks.
