<VV> ignition timing problem on a 110

[N. Joseph Potts]

You are masking a problem. The spark is supposed to advance as vacuum
increases. Now, it doesn't.
     Until you find and fix the ROOT problem, I'd recommend retarding the
base timing to the point where you don't get the pinging with the
vacuum-advance hose attached. Remember when setting your timing to a
(number) specification to do so with the vacuum hose unplugged.

Recently, I WAS having a problem with pinging. The car is a '66 110/4 and it
was very hard to start from a stop without pinging. It was like starting in
second gear. Plus, it would also ping when slightly bogged while going up
hill or being in too high a gear.

Now it runs fun, no pinging and easier to get moving from a stop. What
perplexes me is the way I fixed it. I simply disconnected the vacuum
advance. The car has an almost new Dale distributor, Pertronix II and the
timing is set at 14 degrees BTDC.

So, is this a proper fix or am I masking the real problem? Thanks for your
comments.
