os 55 dies when back at idle
Hi guys

This is a one gallon at most os 55, running on 30% optifuel 1.5 turns on the needles and running at 2000 rpm, lots of smoke.

As soon as i land and pull it back to idle it dies, if i keep the throttle higher for a moment and bring it back slowly i can then get it back to idle with out dying.

If i go any richer on the mid needle it is very hard to get it up to speed, it gurgles and dies.

Any thoughts?

Try putting a new plug in and check the low end needle.
