when i was racing this weekend my blaster had a miss on the first race it was not that bad as in it didnt cost me any place but as the day went on i felt it losing power with every lap and on the 4th and final race of the day it cost me 2nd place X( but when u went out to the garage it wouldnt start . i found the problem was the head gasket there was no damage wat so ever but the nuts weren't very tight and it was missing 1 nut is this comon problem with blasters and if so how often should i check the head nuts
