I know allmost everybody runs Webber carbs on beetle but I have access to a few Stromberg carbs. Has anyone used them and what kind of results do you
get.

You thinking as a single or a set of dual carbs?
Manifolds could be an issue

I'm running a single stromberg, bolts straight up to manifold, It was either the 1600DP 30pic1 or 34pict3 manifold, i forget.
Biggest issue is the linkage. its still not revised, but i'll be going a different route soon. Where it sits on the stock manifold is at a funny
angle. The stromberg was the first of three carbs I trialled to not have lean issues or flat spots, as its not stingy on fuel like a couple 34pict3's
(i was running a 009 though). However, it is a guzzler. you can buy adjustable main jets for it, but i think the fuel consumption in my case is the
over generous accelerator pump.
I didn't bother hooking the manual choke to a cable, it idles without it and doesn't take long to warm up.
Overall i'd say its good as its 'simple' and very basic. but not what i'd call a performance upgrade.
OH! PS: if you hook hard left turns quickly, the motor will cough, i believe its from flooding as the fuel bowl vent tube sloshes a gobful of fuel
down the manifold.

Chris,
You can adjust the stroke of the accelerator pump on a stromberg so it will deliver less fuel. The linkage underneath has 3 holes to choose from, they
are set on the middle one for stock.
You could also try dropping the float level a bit to discourage the cough around corners. As well as easing the general sloshing about, that will also
lower the available amount of fuel in the accelerator pump chamber.
Barls,
I would love to have a chat with Grumble about the twin setup. I have a 36 horse I would like to try it on.
Regards,
Matt.

Is this in regards to Strombergs as fitted to old Holdens? A Stromberg off a 138 or 149 being about 2.2 or 2.4 litre engines. This may work well on a
warm VW engine. Has anyone tried it?

Yep! Done it a few times, for when I'm too lazy to mod the Solex 34 for more airflow.
Strommies work great. I had a giggle when I read Chris Leete's comment (above) about coughing when turning left, mine did it too, as it also did on
the 186 kingswood I pulled it off, and as they also did on the 250 TC Cortina, etc. A minor issue though for a streeter, you really have to THROW it
around for that to happen.
My experience with them is all good. Smooth idle, same or better economy once jetted, easy to fit (bit of a PITA getting the linkage angle perfect),
and a noticeable power/torque increase.
Get one off a 186 or 202, the 250 Ford Strommies are a bit big for a little dak-dak, and the early 149/161s are the same airflow as a Solex 34. Plonk
it on top of a CB Performance centrebranch and there is hardly any difference at all to an isolated runner single with a small IDF Weber.

Yes, The old Stromberg/Bendix is a good choice for a single carb replacement on a Type 1.
It is handy for initial tuning/set-up to install a externally adjustable main jet kit.
Here is a site where you can download a copy of:
FB/EK HOLDENSTROMBERG CARBURETTIONENTHUSIASTS GUIDE
http://www.scribd.com/doc/68315221/Carburettor-Guide
It covers from 'FX thru to the end of the straight sixs (not just FB/EK)
This is a great carby manual.
The write-up for the adjustable jet is on pages 64 & 65.
You have a choice of several choke sizes. Probably best to match your current manifold hole.
The choke sizes got bigger over time, in the Holden. Though this range of carbs was used in a lot of USA sourced cars - it's in the book.
Years ago, I put one (FJ Holden sourced) on a 1200 with a 1400 big bore kit. 1600 Super Bugs could beat me in first gear, but if I started in
second, I would pass them while they were changing into second and would continue to pull away and had a higher top speed.

Yeh I've got access to range rover ones as the early ones run a dual setup also have a workmate that is a guru in tuning them he's a Torana nut.
More research needs to be done.

In the '60's and '70's the stromberg off of a 138 grey holden motor was a very common modification for your vw. They bolted straight onto a 28 or
30 pict manifold, needed to be rejetted and modify the power valve. Then all you needed was to cut off the throttle arm (where the barrel bolt is) of
the vw carby and weld it onto the holden carby. I think I still have one off a 1200 40hp engine if anybody is interested?
Cheers Dave

Ken Virgin used to sell complete sets with manifolds and linkages. I have a set of KV manifolds and the linkage. He sold many sets in SA and they used
to liven up hot 1600's.
