actually andy both of my cars the tornado xp and the volcano were extremely tight when i first got them, before the first start up, i think that is why my pullstart broke on the tornado. It was a little pain to get them started from what i thought was a lack of lubrication but after i primed the carb it was still the same so i thought it was hydro locked and took out the plug but it still felt very tight. all i can say is that with the volcano i ran at least 25 tanks and so far no problem at all and it has the same problem as the tornado. the tonado which is newer and has much less run time on it seems to be fine in the engine dept. but the rest of the buggy has been a headache so far.
