Hi, I've got an 18RGU with Weber carbies,
and the previous owner has removed the
vacuum advance. The timing at idle speed
is still correct, but I'm not sure whether
the timing is correct at higher speeds.
So my question is; is it common or useful
to remove the vacuum advance when using
aftermarket carbies? The previous owner
has done some foolish things with the electrics
so I'm not assuming there is a good reason
for this alteration, but on the other hand it
might just serve some purpose. Advice
would be appreciated,
