Interesting: This is the symptom I had on my GT186. Whenever I went on reserve, the engine backfires. Tried various things to figure this out living with the backfire until it took out a set of reeds
Took the top end off, and found the compression was way to low, although the squish was correct
Had the cylinder head bowl re-profiled to raise the compression, and a never had problem since, no backfire nothing..
