Hey guys. I'm new here, hv just got my new Revo 3.3. I hv done the break in procedure as per the manual for 5 tanks. Now, i'm facing problem with tune up and overheating of the engine. The engine starts up fine but it won't take load and the car won't move much. Also i think excess fuel comes out of exhaust pipe. I tried turning the high speed needle 1/4 turn leaner and richer but no appreciable difference. I'm concerned becoz the first 6 tanks the engine ran fine, it was taking load and the car was running fine, but then now it won't even move and there is no power to make any kind of run. And i'm using 16% nitro fuel for my model. Please help and suggest some solution. Thanks.
