sent this to Richard, then read your post. I now am joining you in the
confused arena, as up until now I thought I knew what I was talking about,
now, humbly am not so sure. The original reply was how I was able to make
vacuum advance work on a Weber or Delorto Sidedraft. As to a late model
1275 with SUs I am in favor of ripping all the smog sh*t off and replacing
it with a Weber. In 12 years, it has never worn out throttle shafts, never
gone out of balance, never ran out of dash pot oil, looks cool, and runs
great. Just my .02 worth, though.
Only cost me a 6 pack of good beer to get it smogged, and starting last
year, is smog exempt in CA.

The age of the carbs I looked at is unknown, although they are late smog SUs
with the little spring & pin in the butterfly. I thought 69-74 had these,
but I guess I was wrong. Just be thankfull you are not trying to figure out
where all the hoses go on a 79 1500. Bought one one time with all the parts
in a box, before computers and lists and such. Had to put it together based
on the worn out decal under the hood. Now that was loads of fun!
