    Default Recording vs non-recording tachometer cable

    Saw the tach jumping a bit, winding down to zero, then bouncing to above red line, and then settling down to a small pulse, then steadying out completely. Very intermittant, as in once last April and then again a couple days ago.

    I'll try lubing, but: Spruce, Univair, etc, offer cable for both "recording" and non-recording" tachs. What's the difference, and how do I know? Googled, no luck.

    you have an hour meter in the tach? If so, its recording.

    Mechanical tachs suck on just about every level, do yourself a favor and get an electronic tach that is actually accurate.

    Figured it was that. Alaska flying story: I was based at Elemendorf from 89-92. Had a 7eca. Was flyijg back from Homer, late fall maybe, early evening (dark), and I smelled fuel. Right tank venting like mad out the top (cap I thought, turned out there was a crack at the neck), left tank has maybe 6 gallons in it. I dropped in to Soldatna, and got some very expensive after hours call out fuel. But grateful for it.

    Cheers

    Once I got used to reading the digital tach, I really like it. Mag check takes a few seconds longer.

    I see they are TSO's but seems like it will take a 337 FA, Yes - NO?
