Agree with Gould on this one. Also, you may check with the tach manufacturer.
I
had a tach go bad after the boat warranty, but found that all the instruments
had a ten year warranty. I sent in the tach, they sent me a new one. For a
nominal fee ($10) I could upgrade the warranty to lifetime. I was too cheap
to
do that. Besides, one of these liberal potshots might just get me sooner than
later!

Liberal potshots? :-)
You know why you got such a cheap deal on the tack swap, right? It's a liberal
plot.
