Quick question vintage Mooney officianado's,
I've put roughly 35 hours on my new to me 67 M20F since taking ownership and finally was able to download the EDM 700 data. The engine is a Lyc remanufactured IO-360-A1A installed in Feb of this year by prior owners. Normal cowl but it does have the lower cowl cover. I'm seeing a consistent temp split between my #2 (hottest) and #1 (coolest) cylinder of ~70-80 deg F. (attached pic of data from one flight). Engine now running Aeroshell 100+...max fuel flow indicated during takeoff ~15-16 gph
She runs smooth, during runup with the JPI Norm mode, all appears to respond as expected. Figured I'd ask if there is a 'normal' or expected temp differential between hottest and coldest cylinder...thoughts ?
