GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
The engine backfires on acceleration. Then runs perfectly fine. Slow down fine. Give throttle and again backfires before getting to plane. Then runs fine again. Slight rough idle when warm. No stalling. Cap rotor plugs and wires? Runs at normal temp. Can anyone help with this?
