[Healeys] Tach rebuild

[John OBrien]

Hi Listers:

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.

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.

Thanks for any info.

John O'Brien
