3W106 Running Rich Inverted
Got a QQ version 3W 106 on 3w canisters, with right angle carb stack, in QQ's 102 Yak, that seems to richen up when inverted or rolling at about 1/2 throttle. New engine, starting 2nd gallon of 32 to 1 oil mix. Seems to run fine over half to wide open. Is this that I need more time and tuning on mixture or a air flow problem or what???? Could use some help from someone with same set up.
Thanks Rick

The only way my 85B2 would run right is to run the vent line to a balsa box in the fuse. The box is ca'ed together and is airtight I shoe gooed the line in. I still ran the elbow on the carb. I was having problems in knife edge flight. It took both to get my 85 to run good in any attitude. Good luck

RE: 3W106 Running Rich Inverted
Its funny, on some 3w motors, the 90 degree intake makes it better, or makes an engine that doesnt need it run worse. If mine has the intake and I cant get rid of the burble, I just take off the intake and run a line back in the fuse, and 99.9% of the time this fixes it. Also, the 3Ws and Tilotsen carbs do not like to run rich, they are more sensitive than a Walbro. Lean your top end as well and that should help, not just the bottom.
