To get my 1975 Stromberg equipped MGB to pass emissions in Connecticut
required carb and ignition settings that made the engine suffer so that it
could barely power the car to the testing station.
First thing I would recommend is to set the timing. It may be quite retarded
as that is what we had to do. Retarded spark causes the engine to be powerless
and to run hot.
Remove a couple of spark plugs. Are they grey / hot looking? If they are,
richen the mix, with a barely perceptible tun of the mixture screw. Check the
book foi "in" or "out" as I forget now which richens the mixture.
Also look carefully at the intake manifold to see if any rubber hoses or the
line to the brake booster have blown off from backfiiring.
Be of good cheer; it's much easier to get it running right again than to get
it to pass emissions.

Hi all,
I have been lurking on & off for a while, observing the concern about
traffic.
Maybe this will help.
I need to do a complete retuning of my Stromberg. From the height of the
butterfly ( don't know what else to call ) to timing & finally the setting of
the carb. As age overtakes me, I'm not able to follow the manual.
Here is the problem. A "well versed garage" took it upon them selves, at my
request to get the 75 B thru'Aircare. (smog control) they got it passed but
when attempting to bring back the performance side, they gave me back a B
that
misses constantly, has no power up hills & overheats ( steam billowing from
the rad), doesn't start for a long time while cranking. Oil in the dash pot
always.
Is there someone out there who would be prepared to help me set this carb up
for both performance & reasonable fuel consumption.
I live in North Vancouver BC Canada so any local help would really be
appreciated.
Best wishes & a healthy New Year.
ps.I have a timing light etc.
Aubrey
75 BE
