Hi, Fella's
Having trouble tuning my .21 buggy motor. It idles fine, starts fine, blowing good smoke . In saying that when I pull on the trigger the motor blurts a few times then stops with a puff of smoke at the end. Using 20% nitro and a #6 hot plug from O.S
If there is any good tuners out there that could help me with the tune I will be very grateful. Cheers
