and idles okay as well. i seem to have noticed my exhaust is a bit dark though. and i checked my spark plugs, and they seem to be black, not oily but black and dry. i have ordered the luminition ignition set from Bull Motif, and think that by changing it and the plugs it may improve.
any ideas? on adjusting the mixture on the carb, and how to do it correctly. I am sure we have some experts here who could do it with their eyes closed.

I'm not an expert but as no-one has answered your query!
There is a brass nut you can move with your fingers on the underside in the middle of the carb. Turning this moves the jet up and down and adjusts the mixture. Down (turn the nut clockwise- I think) for richer and up for leaner.
There is a lifting pin on the underside of the carb to the left of the mixture nut (your left from the passenger side of the car) lift this very slightly, a fraction of an inch- and this will llift the piston in the carb. If the engine speed rises quite a bit then the carb is adjusted too rich. You need to screw the mixture up (anti clockwise from above) a flat at a time till lifting the pin makes only a slight change in idle speed.
With a leaner mixture, the idle may be higher, adjust this with the idle screw which is on the top of the carb near the throttle cable. Screwing this in raises the idle speed, screwing out causes the idle to drop. It does this by adjusting the opening of the throttle butterfly thereby letting more air in and out.
I wouldn't bother with electonic ignition, if you car runs fine on points, just keep it that way- annual change of points and condensor and a perriodic check/ clean and the standard ignition system will be fine. These "electronic systems" can become unreliable and leave you stranded. Points can be fixed by the roadside, but in reality, with proper servicing and decent parts they don't often give trouble.

I use the Lucas ones (points) and keep and eye on them occasionally- gap, condition etc. Are you confusing rotor arms with points?
There is no way to tell if your electronic ignition is on the way out- it just fails. In general- if you want a reliable, easy to maintain daily drive Minor- keep it standard.

Exactly - keep it simple. Points are just fine for a Minor. If your car starts and runs well - leave it alone !! It probably just needs a good fast run to clean the plugs off slightly - but if the plugs are of uncertain age by all means stick in some new ones. But it IS worth while inspecting the air filter - is it clogged up with dirt and oily mess ?
