Ignition timing

[higgins]

OK guys, I've read almost everything posted here on setting timing. /bcforum/images/%%GRAEMLIN_URL%%/thumbsup.gif

There still remains something I am still not clear on.

The fact sheet for my 100/6 BN4 Longbridge model states <u>static</u> timing 6° BTDC.

Later models state <u>dynamic</u> timing 15° BTDC

How is 6° static timing set or have I misunderstood something along the line /bcforum/images/%%GRAEMLIN_URL%%/frown.gif

I have a standard strobe light without dial.

Question: The notch should be painted white, or black, or lipstick gloss, or whatever.

You've also mentioned in the past to place a mark for 15° 1/2" on both side of the notch.

Unfortunately, what I am not quite clear on is, when I set the dynamic timing, does this mean that the notch has to line up with the pointer or that the 1/2" mark has to line up when turning the distributor?

I am able to set static timing with the little 12 volt bulb, I now want to go a step further and be able to understand exactly how it works.

Lets see, Static timing is setting the timing with the engine turned off and requires only an inexpensive test lamp. Dynamic timing is setting the ignition timing with the engine running and using a timing light. I usually use a dynamic setting of 12-15 degree BTDC. A timing light with a dial aids adjustment because you set the dial and just look for pointer and 0 to line up on the crank. Static is usually used just to set the initial adjustment.
