Hot Idle Instability / Micro-Surging

[PhatRV]

I had a couple of flights where the temperatures at the destination airports were over 100 degF. I had the similar surging described in my earlier post. I kept the RPM to approximately over 1300 for a couple of minutes while doing the checklist before lowering it to over 1000RPM. After the runup, the surging mostly subsided. This is the pattern I expect when flying in the hot summer months.

I have this too. It was made a little better by going with smaller fuel restrictors. I think part of my problem is having a very light prop. I think if I put a balancer on it or a CS prop it would help.

Good to know. I plan on stopping by airflow performance tomorrow to pick some up. Yeah the prop is pretty light too
