If you pull the dist and add a piece of hose thats
snug on the shaft just a little longer than the space
between the bushing and where the shaft comes through
the dist housing that should take most of the timing
jump out of it.. once you do that and if it corrects
it then use a clamp on sleeve for it(they're cheap)..
might try a bit larger squirter front and rear..
if it gets better try larger... when you went higher
on the base timing did you restrict the max timing..
that takes welding up the slots.. otherwise you will
end up with way too much timing... also.. keep the
vac unplugged at the dist but plug the hose until
you get a handle on this
