I purchased a used Supertigre 90S. I can't seem to get the low end adjustment correct. When flying the engine will sound fine but when crusing at about half throttle the engine will abruptly quit. (no sputter, just die) Could it be possible that I have the low end adjustment too rich and the high end adjustment to lien and the engine is getting hot and quitting. About how many turns should the low end adjustment be screwed out. (is there a rule of thumb for this?) I read somewhere where the high end adjustment should be 2.5 to 3 turns from closed. My engine liens out much better at about 1.5 turns from closed. I had 3 dead sticks yesterday and each time I thought I had the problem fixed...............my luck and patients are running out with this engine. HELP!

Please see this about getting your carb set up:

If your engine cannot take a "set", then there may be other problems.

I put a Tower Hobbie pro 75 carb. on my S90 runs great and easer to set up
