hi there. just built my new 3.3 engine for my tmaxx (after the old one blew up) carby is set to factory. the engine won't start or idle unless I'm giving it some throttle. what's the issue with it? straying to get over spending more time fixing instead of using my tmaxx. new glow plug, crank case, carby, piston and sleeve, bearings, cooling head. only thing original is the crank n ez start adaptor
