Hi Mick,
I'm with Mike on this as well, I recently installed one on my car, and as Mike says I can't believe the difference it has made either, must say I have been very impressed so far, my car runs much better now, i still have popping on over run but I'm attributing that to either an air leak that I'll never bloody find or some other CIS related quirk. the whole process should take no longer than 20-30mins if you're methodical (or slow, like me

)
turn engine by hand until rotor points to no.1 cylinder, line in the dizzy and Z1 on crank pulley
pull distributor out, remove rotor & points
screw in the new module loosely in place of the points and run the wires out where the points pickup wire was.
install the magnetic ring over distributor cam (found it quite hard to get on all the way down the cam, but perseverance paid)
then set the gap between magnetic ring and module with the plastic spacer in the kit and tighten the module plate.
reinstall dizzy, remembering to point the rotor a bit behind/forward of the line on the dizzy depending on which rotation your dizzy has, as when the gear engages it moves slightly, ideally you want the rotor to be as near as dammit to the line in the dizzy at no1 cylinder when the dizzy is fully pushed in.
connect the black wire from the module to the points/cdi trigger wire (the one which used to attach to the dizzy)
connect the red wire to fuse number 3 on the fuse panel (make sure you have switched +12v at this fuse)
put the rotor back on (you might have to file part of the bottom off the rotor to get it to fit properly on the dizzy cam so that it's notch inside goes into the slot in the dizzy cam)
refit cap
start car (hopefully

)
set timing and never have to worry about those pesky points ever again
Hope it all works out next time, if it were me I'd have one more go, it might take you longer to get the points gap/dwell angle & timing dead on, especially if your dizzy cam is worn as mine was, but then i was aiming for 38 degree dwell angle on the button, as you can imagine... it was a test of patience
Hope this helps and once you've got it installed and the car running i hope you'll be as pleased with the results as Mike and I are
