Aircap:

First, no reason for you to get a unisyn for your 220 until you get a pair of carbs to adjust. I am assuming your engine has the original single Stromberg carb. I suppose it could be helpful on your motorcycle duals. A CO analyzer (not CO2) can be a help, especially if you have an FI engine and live with strict smog rules on old cars. If this describes your situation, the GasTester model is really really good and fairly cheap at $200. I love mine, but do not use it on my carbed cars, only for the FI in my SL. You really need to have a good solid understanding of the car and how it works, and how the analyzer works, to realize full benefit from the CO analyzer. For carbs, I like the old spark plug reading, vacuum gauge and tachometer watching skills learned many decades back when that was all we had for diagnostic equipment. They all still work on old cars like ours. Helpful hint...go to a used bookstore and seek out a copy of an early 70s edition of Martin Stockel's "Auto Service and Repair."

For now, I'd recommend continuing on your path of systematically renewing the worn bits and pieces of your basic car. Sidebar...the old points and the fact that they were still working for you should demonstrate their basic value and reliability. The old dears have proved themselves to be tireless and under appreciated ignition work horses for decades. I had a Pertronix on my M180 engine and removed it simply because I have an innate distrust of mystery parts sealed in black plastic and epoxy and that are not repairable with a swiss army knife and a matchbook cover.

I like the old-fashioned method of doing things with my old cars...it is a relaxing bit of therapy from my everyday work. If your 220 is not an everyday driver...even if it is...mastering the old mechanic's skills (the genuine skillls that are based on true knowledge and an understanding of the physical relationships of the machine's systems, not the shade tree mechanic's old wive's tales) all this is extraordinarily satisfying. It can draw you into the Zen of your engine; learning to understand its language of communicating problems, and its operating contentment when all things are right; it will leave you feeling that you have accomplished something tangible and measurable at the end of the day.

Good luck with your 220; glad to read that you are making progress.
