I have a 3w 106cs with about ten gallons through it. I have the metal reed block holder update installed and am running it with 3w Canisters(this made little to no difference). I have an untuneable midrange burble. It doesn't seem to matter to what extreme I go too on the top and bottom end I can't seem to get it to smooth out. From about 1/4 throttle to 3/4 throttle it stumbles along and then once you get past 3/4 throttle the power comes on hard. Not too much fun when your flying 3d right on the deck. Running the bottom lean makes not difference to the midrange and same for the top end. I love the top end of this engine but if I can't get the mid to settle down I'm going to use it as a paper weight. I've been running two strokes for years of all kinds without any real issues until this engine. I have a rebuild kit for the carb that I'm going to install this weekend. Any suggestions would be appreciated.
cheers,
Richard...
