Uh-oh, Ed, I gave you the story for TE-20's after SN#36151. Just saw your SN in the earlier post. The IT manual lists two methods for determining the TC position: "a line on the crankshaft pulley indexes with a line on the timing gear cover. On other[models], the TC point is when two punch marks on the flywheel are in register with identical punch marks on the flywheel housing starter motor mounting pad." -- remove the starter to see the marks! Good luck! Tex

Ed, setting the time on this baby is easy, about like the old VW beetle. Anyway, here's how I do my 1949 TE-20:
1. remove all spark plugs(makes it easier to turn the engine over)
2. remove distributor cap
3. remove plug in peephole to flywheel timing marks(located below starter)
4. using a wrench on the nut on the front of the crank, turn the engine clockwise(I think -- watch the distributor: the Lucas should turn clockwise,
but my Delco turns counter-clockwise)until you see the distributor approach the #1 cylinder location.
5. continue turning and watch for timing marks on the flywheel -- I use a mirror -- stop when 30 is centered in the peephole. This represents the full advance setting.
6. Set the points gap to 0.015"(Lucas) or 0.022"(Delco) if not previously set.
7. loosen the distributor clamp so you can rotate the entire distributor comfortably -- not too loose.
8.clamp the thinnest paper you can find between the ignition points
9. turn the top of the distributor shaft clockwise(Lucas) or counterclockwise(Delco) as far as it will go to simulate full advance and hold it there with one hand
10. rotate the entire distributor body opposite the normal rotation of the distrib shaft until the paper just begins to loosen between the points. Your other hand holding the distrib shaft will be forced to follow, but keep the shaft in the full advance position relative to the distributor body. Turn the distrib back and forth through a range of about 10 degrees a few times to get it just right. This represents the distrib shaft location when the points just start to open at higher rpm, and the flywheel position should still be 30-32 degrees BTDC(before top dead center)
11. With 3 hands engaged in #9-10, use your fourth hand to snug the distributor clamp bolt when you get everything right.
The assumption is if you get the full advance setting right, the idle setting will take care of itself. I have used a timing light after following the above steps and found idle right about 0 degrees and full advance at 31, as set by the paper method. Checking for the paper starting to get loose is more accurate for me than trying to eyeball the tiniest possible gap between the points.
These instructions are mostly right out of the IT manual, with some personal suggestions added. I included the Delco rotation for other readers and tried for clarity for guys with about as much experience as I have. Hope I didn't insult anyone with the basics.
Good luck! Tex

Tex,
Your timing article was very good, however I havn't yet found the "30 " on the flywheel viewed through the peep hole. I ended up timing it by ear. Strange as it may seem, in my I&T manual it stated the Lucas distributor on the TE20 turns clockwise, however mine turns counterclockwise!
I bought points and condenser from the local dealer and he gave me the wrong ones. As I had the old ones along ,he then matched them up and said it was from a TO20. My distributor is a Lucas D3A4.

The retard springs in the distributor were broken. I can't seem to locate springs ,so I used two other springs that I had to shorten.
Do you know of any one that may have the proper springs? The tension may have to be just right to let the govener weights fly outwards just enough to advance the timing the proper amount for the speed of the engine. I don't know if this is true ,or is there only two settings all the way retarded to start and then all the way advanced for any engine speed?
Thank you,
Regards, Tom

Tex, Thanks for the post I think I'll copy it so I can use it later. I got a little lost when you talked about opening up holes to peek through. But then I just bought my TE-20.
