<div>Keep looking for archive articles John. I recall that a very

[Healeys] Tach rebuild<br><br>Hi Listers:<br><br>The tach on my BJ8 does
not show the correct RPMs. On a cool morning it shows what I believe is
fairly close to the right numbers, but as the car warm, or the day warms, it
reads higher and higher for the same speed. I know it is not the clutch
slipping. I saw some articles in Healey Marque magazine showing
how to rebuild and test them, but it requires a oscilloscope and some other
specialized equipment I don't have, so I'm wondering if you guys have a
recommendation for someone that might rebuild them.<br><br>I imagine there is
also some info in the archives, but my antivirus software flags the archive
site as a malicious website and doesn't want to let me access
it.<br><br>Thanks for any info.<br><br>John O'Brien<br><br>'61 bugeye
