I'm updating my problems I'm having trying to get the BB airborne with my new YS 110FZ because there's several people interested in how it flies using it. As of now, the YS should be on it's way back to YS performance for a through going over. I've tried all I know to do to try to get it to run but to no avail. When I get it back we'll see. If it still gives me this much headache it's gone. I'm very tired of burning fuel and not being able to fly the plane.lol

Hi Suitcase, What was the problem that you had with the Y.S.? My winter project this winter is putting a Y.S. 120 in a Cermark 120 Pitts S2B. I got the engine NIB about 4 years old. I hope I dont run into your problems with mine. Was it the top end or the low end that you had trouble with? Looking forward to how yours turns out. wayne M.

Hey Suit & Wayne,
Okay, so we have a new place to yack about JBB's! I don't think the JBB is the problem with that engine...... I never had good luck with idling the darn things(YS) They are great for transitioning and top end power but the three I had would never idle. I would be suspicious of the internal workings for it's pump mechanism. I adjusted and adjusted and never got it to work. I let "YS" owners try to get it running right but always ended up swearing at the motor! Glad you sent it in for service. Slap ANYTHING on that JBB and go have FUN flying it!! You're missing a great airplane when whatever motor is on it doesn't perform for you!

Hi Ice, Thats not what I wanted to hear but, I will wait and see how mine performs. I agree with you about the B.B. It is the plane that stays ready to fly now. Wayne

I've had the BB for at least a year and love it. My G26 died one too many times and I sold it and bought the YS. Trouble is I've burned almost two gallons trying to get it to run right. Every time I reset it to factory and start over it acts differently. If it did the same thing each time I would say, OK it's me, but it doesn't. One time it will die soon as the glow is removed. Next time it will not transition, next it will but dies when returned to idle. I've tried it all. RVator and I can't figure it out so I sent it back to YS performance. If they tell my they got it to run without actually changing anything, I'm selling it. I have one on my Mayhem 3D and once they took it and did something to it, it runs great. I've never done anything but set the top end and the idle with the trim.
