Only thing Ican say is hang in there. Abrand new motor is the biggest pain in the butt. Iwent throught the same trouble. Couldnt get it started then did but later on could not get it started again. Iended up putting a roto start on mine becuase Ihate pull starts. In the end Iended up sending mine to Redcat to check it out and set my niddle correctly. Got it back started it up finished the break in. Once you get that motor broken in thing become much easier. Mine now starts with little effort and I enjoy running it all the time. Like Isaid you just got to hang in there.
