John, yes, when I flipped mine the first time, with the plug wires facing DOWN, the mag side was indeed VERY tight. Once I figured out that everyone wasn't flipping the coil but simply rotating it, re-did mine so it was NOT flipped, but rather just rotated. Now my tach seems to be functioning just fine -- no more 9200 RPM peak recalls! I didn't really notice if the tack lag was improved or not -- I didn't think it was that bad to begin with, and normally I run my tach on the digital display anyway. I know now that Cat's fix says to flip the coil so the plug wires are down, but I'm not going to mess around with mine anymore unless the tach starts doing funky things again. As you can imagine by now, I've about had enough of this tach/coil thing by now! (But any further questions, go ahead and ask anyway!) -- Roy
