Triple Weber choke

[k2chronic]

The 1973 240 I bought has triple webers but their chokes are not hooked up. Does anyone have any advice on how to fabricate some linkage for these? I live in a fairly cool climate, so I assume I will need a functional choke. Am rebuilding the engine, so I haven't started the engine yet to see how these carbs perform. Thanks.

You probably will not need the Weber "Starter Devices" to be hooked up in order to get the car to start.

As long as you are pretty close with your jetting and set-up, then a few dabs on the throttle pedal before turning the key will usually be enough to start a cold engine. It only takes a minute or less to get an idle speed that makes the car driveable ( as long as the rest of your engine is not too radical ) and then it should run just fine.

The problem with the Webers is that the Starter Devices pull "on" from the front of the engine ( whereas the original Hitachi SU's pull on from the firewall ). Therefore you would need to fabricate something that loops around to pull from the radiator side of the engine, and the stock choke cable is not really long enough for this. You could possibly Frankenstein something up, but it would be MORE important to make sure that the Starter Devices were fully closing than to have them operating in the first place.

You might be fretting over nothing, as a well-built fresh engine with proper compression and a clean spark will run very nicely without too much of a warming up.

I used to run an L24 on 40DCOEs here in central London as an everyday driver, and had no trouble at all in starting with no Starter Devices hooked up ( I just diasbled them and made sure they were fully closed ).

Give it a go.

Good luck,

Alan. A very belated thanks for your reply. I didn't see your reply until now because it wasn't attached to my thread. Plus the fact that my handle is not K2chronic. Don't know how I wrote a thread under his handle. I have tried starting without the choke(starter devices) and it is quite difficult. I live at 6500 feet in Colorado and it gets cold(below zero degrees F). I believe though in the summer I probably wouldn't need the choke and won't be driving it much in the winter anyway.

Hi Tanny,

Crikey - 6500 feet! I'd need Oxygen to just walk around up there.

In that case, you probably WOULD find the Starter Devices useful. I should imagine that kind of altitude would make your car quite difficult for set-up choice too ( ? ).

When I drove my car over the Alps from France into Italy, it behaved REALLY badly at the high altitudes. The setup for the jetting etc. was done at roughly sea level ( or a little bit above ) and the big change in barometric pressure up in the mountains seemed to throw it all out of the window. Was fine once I got down to the lower levels again.

I would have thought this would force you into making a decision as to WHERE you chose your setup to work at. Either down at the lower levels or some kind of compromise?

Good luck with it, anyway!

Cheers,

Alan T.

Alan,

The carbs were supposedly set up for this altitude and they do seem to run well. I have no idea how they will react to sea level oxygen. I haven't had the car on the road yet, so I don't know how it will run under load. I just finished rebuilding the engine, replaced brake and cluthch master cylinders, clutch slave cylinder, both rear wheel cylinders, rebuilt front brakes, and am now repairing odds and ends(rust hole in floor pan, fuel pump, window sprayer, etc., etc., etc., etc.) on a car that was garaged since 1982. Hopefully I will get it on the road in the next few days. Have fun, Victor.
