Another Stromberg Question?

[MBL]

Howdy all, Tim here. I am currently messing around with my throttle linkage and am having some difficulty. I have two 97's on an Edmunds intake. Right now I have both carbs hooked together on the passenger side. There is a ball stud in the middle of the rod connecting them. This then is attatched to the pedal itself. One reason I feel it is not working is that the rod connecting the two carbs is one that has the two springy ends....the ones that you stretch out to fit over the ball stud and release to hold in place. The foremost carb will stretch out the spring in the end rather than twist throttle wise after a certain point. So one carb will be wide open while the other is not. Thats problem one...now if I adjust the rod to be shorter on that side...so it will be wide open when the other carb is.... the throttle never fully closes when there is no pedal pressure.

I have thougth of several solutions:
Get a rod that doesn't have the springy ends on them. (or)
Connect the carbs on the drivers side with those carb arms you can buy. And then hook the pedal to the passenger side but only to one carb.

Does anyone have any ideas for this? Any pics of their linkage setups? Any help on this would be great.

Oh and that roll pin on the passenger side of the strombergs...how hard is that to knock out?

The roll pin, actually a "soft pin" that is solid and made of an alloy of whoknowswhat is pretty hard to get out--it is usually quite tight and will tend to mushroom. Get a pin punch that fits and yuo MUST be sure to support carb shaft while you beat this to death.
Linkage needs more thought and coffee, but short answer is that you should set carbs to idle opening you want with linkage OFF, then set linkage so it exactly fits without moving carb lever. Much easier with screw socket type link ends. With stock springy ends, you must achieve a state in which carbs are both seated against solid part of socket, not off their seats and pulling against spring part.

I think maybe I will try it on the passenger side with the screw type sockets before messing with the little pin. Knocking it out sounds like a deal that I would cut corners on...."I don't need to support that" ...then I have a bent shaft...
Thanks

If you do attack the pin, I'd say you should carefully center punch both ends (maybe it will start moving!!), drill just the thickness of the outer collar from both ends, remove collar, and then punch/drill/slay remaining bit--actually, it can be left alone once hand throttle stuff is off.

Isn't that collar pot metal....I could just crush it with some plyers and then cut the pin flush....if I don't intend on using those parts again.
