No good deed goes unpunished...
At some point I lent my trusty, old timing light (dial back style) to someone. No idea who and no one so far has offered to return it. So, I need a new one. Couple of problems though. * Most new(er) dial back and (all) digital lights reportedly don't work with a multi-spark CDI ignition system. * Assuming I need to now buy a "simple" (non-advance) light. How the hell do I know what my timing is set at? Certainly I can hit the 27 BTDC mark and goof around from there, but I'd really like to know EXACTLY what my timing is set at! What do others with an MSD or Mallory use? If using a "simple" light, how do you hit, say 28-30 BTDC? -Aaron |

If you're using a non-dial timing light, the best way to tell what the timing is would be to use a timing scale. Much easier in a Bug, though, as the crank pulley is easily visible from the engine lid opening. Note that some of the Type IV Buses had timing scales bolted onto the fan shroud. Doesn't help that much in a 914, though.
You can paint the edges of the fan so you can see different marks through the timing hole. You get a somewhat limited resolution that way, but you can estimate how far between marks you currently are and get some appreciation of your current timing that way... --DD |
