Seconded re: drop difference, I've had a similar difference with an R2160.

That thing would get quite some abuse by pilots though, I recall seeing a guy over-priming it, pumping the throttle like he was playing a pinball machine, he then gave up and handed the keys back in saying something was wrong with it. I went out to it, and with mixture at ICO and throttle open a couple of inches it fired up, pulled the throttle back, mixture open; all good.

Update: Did a mag check in the P-51 before a flight today and got a 200 RPM drop on L and 300 RPM on R! After doing one overhaul (while the engine was running) I got 70 RPM or so on one and around 250 RPM on the other, a second overhaul brought both down to 100 RPM.

Dave,

Exactly the sort of effect I am seeing in both the Spit and the P-51.

Well at least it's consistent.

Btw, real world, mags are very fickle things. We had to replace a bad mag 3 times on a CV-240 before finding a good one. Worse than that, there were 3 more rejected as soon as they were pulled from stock becaise the graphite o-ring at the base was cracked and/or chipped.

Well at this point, then, I think the concern is that these bad mags don't show up in the maintenance hangar or that there is too large of a margin before they do. Given the above remark, though, maybe after changing mags that show up in yellow we should get another one or two that are still yellow or even red despite being new, hmm?

Considering the developers claimed that fluid leaks don't always show immediately in maintenance hangar after they've started (I don't know if this claim is correct or not), it'd be logical that a bad mag would not show unless the engine is started. Unless, of course an insulator is broken and shorting to ground, or there's some other visible defect.

Anyway, this bad mag thing is quite wide spread. I have like 100 and 200 rpm on Spitfire Mk Ia after 1.4 core update. I think it was the left mag that had 200 rpm. And the result is the same whether I test left or right first, thus cannot be caused by plug fouling while switching mags. And I think there's somewhat bad mag on one (or several) of my P-40 variants. Maybe I should just swap these again and again until I get proper mags. I do hope though that the faulty from the factory ratio would be toned down a bit. It's not on top of my wishlist (I think one of the biggest wish at the moment would be a better, more immersive vibration modeling - I preferred the old one over the current) but it's on it nevertheless.
