Vance touched on something that I have been wondering about. I have been
having problems with my newly rebuilt engine running roughly. I finally got
the
timing straightened out but it runs like it has a big vacuum leak. Believe me
I have checked everything-isolated carbon canister, checked throttle shafts,
new hose to servo,retightened manifolds. Vance mentioned that the engine
should pick up revs when vacuum line is detached. Mine doesn't. I can wiggle
the
vacuum unit and it will speed up or slow down engine speed. Is this where my
problem in whole or in part lies? I hate to buy a new vacuum unit (68.95 @
VB) if it is not the problem. I considered buying a rebuilt distributor but
after the layout for the rebuild I have to lighten up a bit on spending or I
won't have any gas money. I almost forgot-whether I have the vacuum hooked up
or
plugged off does not affect dynamic timing.
