Tach for 337G

[Jim Rainer]

After much time spent chasing wries, inspecting mags, etc. my mechanic now says he believes my tach indicator is bad. Both engines jump around in random fashion. The FE has been intermittent for some months but now RE tach is acting up.

I'm at this point I think it will be better to get a new or used tech than to keep chasing rainbows. I have gone back through the parts sources, etc. and through the thread that was started by Jose on 10/13.

My mechanic thinks there may be some of you out there who have installed dual digital tachs (Horizon?) and have a loose or spare tach indicator.

Any suggestions. I have emailed both Don Neiser and Owen Bell but haven't heard back yet.

Thanks,

Jim Rainer
