Swingy , you sound like your in same boat as me as mine is a 002tx from same place and wife brought me this for early christmas couple of months ago and ive had loads of probs but this might help u . After a couple of tanks i set my needles to the hpi spec then it wouldnt start ! Then when it did it bogged down with no power . Ive now got the low needle set at just under one turn out and high needle two turns out and it goes well and doesnt bog . Just it dont poxy start again without about 10 pulls , always used to be a couple of pulls before carb touched lol . My plug is browny/black with oily wet mixture at exit of exhaust
