RE: SuperTigre mid-range problems?
I think some of the reports you read are lean problems too. ST 's will run lean when other brands will quit. Thinking they are sluggest and loading up. Stay with 10% nitro or lower. Warplanes engines usually get inverted. A FOX IDLE bar plug is the proper heat range for timing and IMO will prevent a deadstick or two. If you could tune a K&B you should have no problem. ST do smoke a lot too. GOOD LONG BREAKIN and needles set right , they will last forever.
