Let's see if I can express this clearly while starting to chomp-down a frozen margarita... I've got dual Pmags, model 112's, on my Lyc. Basically no trouble out of them for 100's of hours, except I removed and disabled the MP vacuum lines when one Pmag developed an internal vacuum sensor leak that was playing havoc with my manifold pressure readings... I knew an eventual upgrade to a newer Pmag model was in the cards when that happened, but have been putting it off. Recently replaced the plugs. Old ones looked really good, but I'm just anal about cheap & easy maintenance items like that. Last flight, I noticed a significant discrepancy in mag drops at run-up: about 50 rpm on the right side, but 160 running on the left. Flew okay around the patch that day , but it got me to worrying a bit. Today, run-up performance was the same as the last time - big drop with the right side off. Still, I wanted to get some engine monitor number in flight to see what might be up. When I shut off the left mag in level cruise, the rpm dropped slightly, and EGT's rose slightly on cyl's1& 2 (I can only read two at a time with my ancient EIS). When I shut off the right ignition, the EGT's again climbed, but the #2 went to redline immediately (and I mean fast, from 1510 to over 1600F) and the engine rpm drop was more pronounced. I repeated the test with the mixture full rich, and even though i was starting with EGT's in the 1380 range, the #2 went over 1600 again, just a little more slowly. In the seriousness of the moment, I never bothered to check cylinders 3&4; don't want a burnt valve or holed piston. Realizing i had a situation that could damage the engine if I lost that right ignition in flight, I called it a day and decided it was a safety-of-flight issue that justified pulling the mags for replacement right away. Unfortunately, the Emagair folks are taking the slow boat home from Lakeland, and it will be Friday before anyone can return my calls. (Hey - I type okay when nursing a bit of tequila, eh?) So here's the question: what's causing this behavior? I was expexting a lower EGT on one cylinder if it was not firing right, unless the timing has jumped. I can see how a very advanced timing on the left mag might shoot the EGT high,but why not on all cylinders? ANd if advanced timing is the cause, why not showing up when both ignitions are on? The right side would be firing too late to help things. I guess it must be retarded timing if anything, but I never knew that problem would drive the EGT up. A plug or wiring problem on cylinder 2 would make the cylinder run cold, not hot, would it not? I'm just really not sure what is going on here, but I am sure hoping a replacement of the mags with the latest, greatest model will fix it all. Even if resetting the timing on the left mag would fix the issue, I still am gong to pony up for the new mags, so I might as well take my down-time like a man and do what common sendse tells me need s to be done. I would like to here what the hive mind thingks is up wityh my airplane . I don't liek not being able to fly for a coiupel of weeks.Now that I've have finished the margarita, the problem really doens't seem that serious. Thanks fro letting me get that offf my chest. Irt's getting dark but it's such a quite evening and the winds are calm. Screw it, I'm going flying whwther the P-mags coperate or not.

Fuel is burning in the exhaust pipe instead of in the cylinder.
