Hello,
We have a 2021 SR 20 we have less than 750 hours on it. Within the first year we had to replace 2 cylinders (1 and 4). I flew it this weekend home. Had the 100 hour inspection done and the cylinder #3 is showing low compressions. A borescope was used and there is no carbon build up. Mechanics said he could try to Lap it and see what happens, and also do a wobble check. If that does not work. Lycoming cylinders are hard to come by. Does anyone have a connection to getting a cylinder faster than this fall? We have our plane on the rental line at the school. So it get’s flown. I don’t understand why this keeps happening.

How does it get flown? School means pattern work and stuff? What’s the procedure to configure the engine for cruise (if it ever cruises)? The Lycoming Engine in the G6 (I assume) wants to be pulled back to 75% and then set to target fuel flow in Perspective+. Do some people fly the Lycoming LOP to save fuel? (Wet or dry rental?). What’s the startup procedure? How is it started at close to freezing temperatures?
I wouldn’t expect TBO from an engine flown by various pilots. And SR20 Pilots used to the Continental generations will mistreat the engine often. The school I rent uses very thorough familiarization procedures and flights. Not everybody gets to use the G6s and no pattern work.

What are the compressions?
Also…
This is very informative. Thanks for sending. I believe the compressions were under 30%. My husband and I fly it mostly and do the correct procedures of leaning and cruise. From time to time we have students learning in it because they have bought a cirrus and are training in it.
It looks like you have two thread of this going. The other one is located here
