i was wondering any of you new people thats into these cars and trucks that after you run it is best to put marvel mystrey oil in the carb and spin the motor overto lube the cylinder now when you go to crank it back up it might take a couple of more pulls but it saves your motor they probley sell some thing else from the hobby store but this is what i use you can get it at walmart and automotive stores its like 2 or 3 bucks for a good size bottle i just take the filter off and just pur maybe half a cap full in it but it really does help so try it if any body else have any suggestions post it on here thanks .jerome.
