I have checked the timing and found some play in it. (the bead on the flywheel jumps arround a little while idling)

I looked at Langdon's HEI dist and it's cheaper than I expected and very tempting.

Back to one of my original questions:Do I need to replace the aluminum and lead plugs after "drilling out the restrictions" as described in the "multiple rochesters" tech section?

Thanks again for all the advice.
