I have been doing my own maintenance for 15+ years. I educated myself by watching the guys who did my paid maintenance, checking what was available in the library, and searching the internet. I'll share what I found with no guarantee of accuracy.
It sounds like you can run yours the way you have it set up without any major problems.
There are a lot of the older manual type tune up tools and guages around. The industry standard tools were made by a company called Bacharach and if you search ebay you can sometimes find them cheap. It sounds like you would need a soot tester and the Fyrite combustion gas analyzer. The latest analyzers are electronic and expensive, but you should be able to find the fyrite version inexpensively. The bacharach tools are pretty sturdy and supplies such as soot test paper and analyzer chemicals are available inexpensively as generic items from internet supply sources. A company named Westwood makes most of the stuff to fit Bacharch.
Once the burner is initially set up by analyzing carbon monoxide and stack temperature to determine nozzle size and air settings, you normally just fine tune with soot test when doing your periodic maintenance.
I watched as several diffent techs did the maintenance on my furnace and all the ever did was change filters, screens, nozzle, vacuum out soot and set air level with a soot tester. When I checked the stack temperature on mine I could see the nozzle was way too big and sized it down. This required changing some sheet metal parts in the burner head which was specified on the specifications from the burner manufacturer based on nozzle size.
When I changed the nozzle size I set it up measuring the CO level.
The optimal CO level number occurs at two places when you adjust the air level - both before and after peak efficiency. Thats why you use an analyzer to trace the level and be sure you are on the right side of the peak efficiency curve.
Also, items such as oil pump screens, oil filters, nozzles, cad fire sensors, and igniter transformers are available from several souces on ebay for the same price the service people pay.
Hope this helps - its good to see there are people out there with a DIY attitude.
And one more thing - wear rubber gloves and you won't smell lkie fuel oil for as long a time after you're done.
