Yup been there done that (and found that my garage isn't wide enough to get the firewall trim out the door).
I've had the dizzy off and set the points gaps on the Mallory Dual Point. They are now set by the book - and to the same setting.
This improved the running and stopped it pinging at 120mph (on the rolling road, obviously, ahem ).
I've got the static timing at 10 degrees BTDC - though after reading George's post I'm thinking of increasing this to 16.
Very interesting being inside the car with alternator fan spinning a few inches from your nose whilst you point a timing light at the crank pulley.
Would a vacuum advance dizzy be worthwhile?
