The Evolution 10cc on the Sbach has been a challenge. Recent over haul damaged an O-ring on the low needle which has two of them, none to be found anywhere, but Horizon Hobby found a carb set and sent them to me! I replaced the damaged O-ring, and set about tuning the needles. Idle is best achievable, pretty much at stock settings, Low 4-1/4 and Hi at 2 (stock 2-1/4).
Idles good, nice acceleration, good high RPM. The pull back to idle is slow. This usually indicates a rich Hi needle, but leaning it doesn't improve it.
She still spits a LOT of oil... at 40:1.
Looking forward to taking her to the field so it can go wonky again. I'll put the cowl on guaranteeing it will.
I like the look of wheel pants, but at grass fields they take a beating. I have 3 planes with them still. I removed repaired, repainted and reinstalled the Sbachs pants.
