I would ask him to set the timing back to the original specs with, perhaps,
an additional degree or two of advance. This is done with engine warm and
running at MG's specified RPM. Unless your fuel in BC is quite different from
ours in New England, the original timing specifications are about right. John
Twist recommends 32 degrees at 3500 rpm----check his site to be certain.
Look at the diaphragm in your Zenith-Stromberg, Moss part #366-040, $3.75.
Just a slight crack in the rubber can cause some strange operation, and these
seem to expire with time.
At one time, in order to get my '72 through CT emissions, it had to be
leaned so much that it barely ran, ran hot, stumbled and, seemingly strangely,
drank a lot of gas. The mechanic with the emissions gauges needed to set it
up so that I could (barely) drive to the CT official station, charged once for
a two-part service: setting it up to pass inspection; resetting it so it
would run properly.
A couple of years later, the gasoline formula changed and the test was
changed from idle test to 2500 rpm test. I could then tune and take to the
test center, and it would pass easily.
As others have noted, the cooling system could be loaded with sediment.
Rinsing it out is not difficult, and be sure to hose out the heater core too.

Hi,
My name is Aubrey & I was involved with the list up to 7 yrs ago. Pse bear
with me.After being idled for 7 yrs, due to my health problems,I wanted to put
it back
on the road.I was an OF then but now I'm a bigger one & don't remember much
how things go
back.
I was recommended to a "so called " excellent fellow who said yes he will get
it through Air Care( our smog inspection ).
Long story short.
He had 2 attempts to get the vehicle running correctly & although it passed
Air Care, it runs ok, with the following problems.
The car overheats.
He said he had to change TDC. Now misses.
Have 94 octane in & it still runs on.
Has ok performance
Chews gas.
I'm sorry to ask you folks but I cannot find this problem in the archives.
Could someone direct me where to look, or if you choose to comment I'd be
most
grateful.
Thank you very much
Aubrey Schneider 75 B
Beautiful British Columbia
