Symptoms:
- Fluctuating idle 500-700
- Idle stutters and wants to stall
- Sounds like a small exhaust leak
- Running rich
- Only when warmed up

I ran through the FSM low idle when warm checklist and couldn't figure it out. Ran a compression test got 3 good pulses by ear on each rotor with max psis of 100 front and 75 rear (yeah rear is low).

Could this be from an exhaust leak? any ideas what else it could be?

with the low compression Im contemplating a new motor also but would like to fix this for now at least.
