Thanks Both for all your help and tips, I really should pick up a temp probe because it's definitely running TOO hot after that 15min's of running for some reason. I was checking around some posts and I saw somebody mention resealing the engine - taking it off the carb and using a sealent to fill any places where air might be getting in - do you think this could be my problem???<div>
</div><div>Its so bizarre and like i said I'm new to RC Nitro market but it blows blue smoke like its running rich but stalls and the engine smokes like its running too lean, how could t show signs of both. </div><div>
</div><div>I still have the traxxas manual - basically like my bible to the car but thank you for the link. </div><div>
</div><div>I'm going to  to try what jim said after I reset the needles to factory settings and go from there. The brake is not engaged - it's almost too loose because its really hard to stop the truck, even with the idle low enough so the car isn't inching forward. I finished the break in period completely before any of these problems arose. Step for step and tank for tank. </div><div>
