I might add that the reason these dist. become "Sloppy"
is bushing wear.
They have 2 oil res. that get over-looked by many owners.
One is a wick under the rotor. That oils the hollow advance
shaft. The other is an oil cup at the bottom, outside that does the main bushing.
Being a point ignition system, many are converting to electronic
ignition with pleasing results.
There are several on the market and they are probably the best short $$$ you can spend to improve the running of these Mechanically Injected engines.
