RE: NGH 9cc Engine input???
Got mine the other day but haven't found time yet to run it. First observation after taking it out of the plastic bag was the motor felt gritty when I turned it over. Flushed it out with WD-40 and much better. I really don't feel like it was dirty on the inside but maybe the piston was dry and made it seem that way. Also I swapped out the prop nut for a better machine grade nut. Will run it this weekend but sure I'll be satisfied with it. Got it at a good price and it will be cheaper to run than Nitro.
