[stag] carb and distributor timing question

[stag] carb and distributor timing question
June 26, 2011 03:35AM
My '71 Fed Stag came with a pair of carbs from a '73. I've now swapped them with
a pair of carbs from a UK stag. The carbs have an advance port on the right hand
carb. My distributor is from a '78 with vacuum advance.
I now want to set the timing correctly for this setup. I have the ROM, but I
can't find the pages. Can someone point me to the right section of the ROM or
tell me how to set it up for this configuration? I have an ROM with a copyright
date of 1977.
Section 5 of my ROM has some numbers, but I'm looking for the procedure.

Ignition timing is covered in section 86.35.16 of the ROM.

But it's basically like most engines, disconnect and plug the vacuum line
(just to be sure there is no vacuum advance or vacuum leak), hook up a
timing light (except to #2 instead of #1 like most engines), run the engine
and shine the timing light on the marks. Rubbing a little white crayon into
the notch in the damper will make it easier to see under the light.

...and set the advance to 12-14 deg. BTDC.

From memory, with the non-vacuum retard set-up I had the timing set to 12 BTDC.
Now I have vacuum advance I can leave it at 12 BTDC and hook up the vacuum
advance pipe.

You don't need the ROM, it is a very simple task. With the vacuum advance pipe disconnected, set the timing using a strobe lamp to 12 deg. BTDC. Re-connect the vacuum pipe and off you go.

"the ROM" is the "Stag (by Triumph) Repair Operations Manual". There are at
least two versions, the early version was loose-leaf in a brown vinyl
binder, P/N 545162. The later version covers Mk 2 models and emission
controlled models (but lacks some of the electrical information found in the
early version), paperback in a white cover with green markings, P/N AKM3966.

Amazon has them:

Or Google for the factory part numbers to find lots of other vendors.

Or they turn up on eBay fairly often. Here's one on CD for cheap
