Engine Tune-Up
« on: June 07, 2009, 10:21:20 PM »
Well, I have just about got the braking system completely overhauled (one small fitting on the back of the master cylinder is still leaking, but other than that it's good) and now I am moving on to fluid exchange (also almost done) and engine tune-up.  I was looking at the engine tune-up section of the shop manual for my 53K, and it has quite a lot of elaborate tests for the distributor that would require expensive equipment to perform, such as centrifugal spark advance tests on a districutor tester.  Are these necessary?  I do have an engine analyzer to test rpm, dwell angle, etc. but it is for 12-volt systems.  Does anyone know where to get one for a 6 volt system?  Also, will an ordineary timing light work on a 6-volt system, or do I need a special one?

These are only necessary if you have a problem with the distributer. All you really need is a set of feeler gauges, a screwdriver and a timing light. A 12 volt should work but not be as bright, or just hook it up to a 12 volt battery. The spark to the plug just triggers the timing light to flash. Set the rubbing block on the points on a high spot on the distributer cam, use the .022 blade from the feeler gauge, put it between the movable arm and stationary part, adjust the points until a light drag is felt as you slide the feeler gauge between them, tighten the points, recheck with feeler gauge, if all is good, put a SMALL amount of grease on the distriuter cam, and you're done. Used to be a special grease for points, but I don't know how easy it is to find today. Don't worry too much about setting the timing to factory specs. Gas has changed a lot since 1953. Try a few degrees either way and set it where it runs the best. These systems aren't as fussy as new computer controled systems, close is good.

Okay, thanks.  That's useful information.  It sounded like the whole tune-up procedure in the manual was a little overboard--unless, of course, something is seriously wrong.  Will give it a try.
