Adjusting the Stromberg needles - HELP!

PostPost by: poiuyt » Sun Oct 02, 2005 1:23 pm

I searched the archives for the answer to this but can't find any.
Maybe there is no answer!

I have a 1969 S4 that runs great but very rich (After a 350 mile
highway run from Stowe, VT to Long Island the plugs are coated with
black dust (as well as the back of the car).

The Haynes manual states that the needles can be removed by taking
out the set screw (I did that) and pulling the needle out of the
piston. When I pull the needle it comes out an wighth of an inck but
is on a spring that pulls the needle back in. I don't have
adjustable needles because the allen wrench on the adjustment tool
does not have a socket to go into. When I look into the top of the
piston I can see what looks like a castelated nut or something of
that sort, not a flat smooth area.

The book says the needle should come out unless I have adjustable
needles, which should be adjusted all the way down then it will come
out. No luck.

Both carbs are the same. Ray at Rdent told me to try carb cleaner to
free up the needle assembly. They are currently soaking.

Any help would be appreciated.

Thanks,

Steve B.

OK - I got the needles out with a heavy application of Gummout carb
cleaner.

Steve,

A great place for parts/service/advice for Stromberg carbs. I had the
same problem on my 72 Elan.
If your fix does not work, try Joe Curto, great carb guy. He is in NYC.

First, better rich than lean

Second, adjustment is mainly on idle, it will not change much at highway speed.

Third, the jets are probably worn , and perhaps the needles, replace both

I know Joe Curto - love his SU Morris van - but I'm trying to do thid
myself. If I can't get it done I'll go to him.

By the way, I finally gotr the needles out and was able to adjust
them. I should have the car running this Sunday and we'll see if it
made any difference.

Thanks.

Steve

1. I agree - but I have to clean the plugs every few hundred miles
and a 350 mile highway run made no difference. Also, the back of the
car gets black.

2. Thanks

3. Are they available? (The needles are B 1 G) And how do the jets
come out?

If they are fouling, that is obviously no good. turning the car black is, if not normal, common

Should be available, any of the usual suspects should have a line on them.B1Y is preferred over B1G, leaner at idle IIRC

Jets used to be a volvo dealer part, long time ago though

Jets press out of casting. Carefully; well supported. Measure the step downfrom the casting to the brass part of the jet and remember for replacing the new ones, as there is no stop. Something like .1"

If that dimension varies from what is called out [is it in theLotus manual or the stromberg books I have, I can't recall] that might be an issue

My S2 (Weber) used to foul plugs every few hundred miles. Switched from
Optimax to BP 98 and no more fouling. The back still gets black after a run
though.

Cheers
