Dave,

Well today I finally got to try to actually fly the thing again.. It idles now, but seems to be changing RPM, hunting up and down just slightly, it also sounds like it has small backfires when throttled back. Idle doesn't seem as smooth or as low as it used to be and today I had to make two deadstick landings. I noticed low speed was speeding up slightly so I richened it 1/8th turn on the regulator, where as before (before the bad fuel) it was slightly rich cause it would slow down just a tad when I took the glow starter off. Also it seems to fly faster at lower throttle settings, I know it's not lean cause I have a nice smoke trail. I used to tune high end to approx 9600 RPM with an APC 16x6, I could get it over 10k if i leaned it out. Today I tuned the same and it also seemed to hunt slightly at WOT.

Please advise..
