timing

RE: 18*

Well, what your saying does make sence. If i give it just a hair more advance after its already running, The idle speed does rise as it should, and It may actually run better, as you say. But i haven't got a chance to try it yet. I just know that if I go more than just a hair, advancing the dist, even with it already running it starts missing and sputtering. I have it just on the brink of that now. I do plan on getting a new, better battery and a high torque starter soon so mabey i'll be able to add that little bit of advance then.

Just one thing, like i said I've never used a light before so bare with me. I understand the 18* advance base number, but how do i figure my all in total? Also if I get my dist set for 18 base,do i go ahead and tighten it down?? how do i adjust the total ignition timing without disturbing the base? I've never understood how to figure that. I one once told that no question is a dumb one so i hope that one didn't cross the line. ha ha...

this article looked pretty complete to answer your questions:
(LOL, old bogie is about the only member that does actually write out the NEEDED long excellent explainations...it would take me an hour to type out just a basic how-to for ignition timing!!!)

http://www.centuryperformance.com/ig...s-spg-219.html

most hei dist's do have 20 or 22*'s of cent advance so if you set the base to 10 you should see (and do confirm) 30 or 32 at 3500 rpms so that all the possible centrifugal added is all in (with the vac advance unplugged)....

to not have more than 36 worth of base plus centrifugal together total at WOT with 18*'s of base, you will need to modify the weights or stops so the centrifugal can only add 18*'s....

sidenote:
anybody got a link to the Lars Grumwald timing article(s) for this fellow....
