im a virgin with these rc cars so im learning every day(maybe a week into it..and the car was used).Well anyway when i first got the car it wouldnt start,Then a buddy of mine got it started but as soon as i put it on the ground it would shut off..So....................I let my buddy tune it up for me. Relpaced a lot of stuff that was bad on the car and put a new pipe on it.....I was at Bennigens 2 saturadays ago....It ran for a while but got hot in about 15 minutes....Then i couldnt keed it running....Replaced the glow plug twice and was told the glow plug went bad both times.....Went to hobby store yesterday put a fresh glow plug in it, still no luck....SO...........................
