I have a 3W 85IB2 TOC ( twin ) that I bought used. The person states it's used very little and by the looks of the engine I'd agree. The engine runs great, and I seem to be chasing the needles just a tad, but my main problem is if I go to full throttle, and then quickly down to idle, it dies. It does this even with the idle set up to around 1800 or better. If I drop the throttle quickly, but stop short of idle, then let it set down to idle slowly it is fine.

Also, it seems when I do have the needles in the sweet spot, then engine likes to smoke just a bit. I am beginning to think the engine is even broken in yet.

I am running it on Redline @ 40:1.

Thanks for any help,

Mike.
