trotle return springs

If anybody has any good input or photos I would like to know I am running twin webers on this Envemo coupe but do not like they way it is hooked up must be a better way nothing worse than a trotle sticking on twisty curvie roads

I purchased two springs from Airkewld for my dual Dell's. They are located where the hex cross bar connects the air filter base plate. I am a huge fan, great throttle response, clean application. Unfortunately when I ordered they had 5 in stock and were not going to make anymore. It may be worth giving them a call, but i did not see them listed on there website.

I will post a picture, I am sure something can be fabricated.

Pete.....I run two "Light" springs....One on each throttle shaft arm, and hooked over the bottom lip of each air cleaner.....Ace hardware, $1.25 a pop......You dont need much at all, but the return force should be applied at the carbs to minimize the effects of any slop in the linkage......That's just my thought....Hope it helps...

My setup is the same as Leon's and, I believe, is the standard method with dual Weber IDFs. See attached pic.

Ok - Pete - gotta ask. What are those chrome exhaust down spouts on either side of your shroud? Is that to preheat the spark plugs?

Yeah, probably want to plug those if you don't have heater boxes.

that answers my next question ill plug them up the crome tips look cool makes fools ask questionsseems to work LOL

Pete:

I think they're 2" ID, so a couple of 2" engine block freeze plugs fit right in - maybe use a sheet metal screw to hold them in.

Since I drive an outlaw, I didn't use the "standard" throttle return spring method. Instead I have a single spring between the fan shroud and the hex bar actuator arm (where the throttle cable attaches). Got a beefy compression spring the right length (meaning a little long to start with) from an ACE hardware store and a plastic hole cap with a mounting flange the right size to fit inside the spring so that the mushroom part of the cap runs up against the end of the spring.

Drilled a 1/8" hole in the middle of the cap to allow the throttle cable to pass through.

The assembly stack-up is: remove the throttle cable from the hex bar arm. Run cable through the spring and push the spring against the fan shroud (it'll more-or-less center around the throttle pass-through tube) . Run cable through the bottom of the hole cap, then depress the spring and re-assemble the throttle cable to the arm and tighten. when it's tight, let go of the spring and it'll push against the arm.

No extra springs hanging around anywhere. Nice, clean setup and the spring is almost out of sight.

Let me know if you need a picture.

Pete, I used Gerber baby food jar caps painted black on my Baja. They just pushed on, and stayed. I drove that car HARD off road, never had a problem with them falling off. Much has changed since High school, and I don't have any kids so cant say if the caps are still metal. I doubt the jars are even still glass. I also read a thread on the Samba referencing completely blocking off the fresh air outlets. It is my understanding the cooling is actually affected negatively by completely blocking the outlets. There was a particular diameter drill bit used to drill out a hole in the center of the cap/block off that kept optimum pressure/air running over the cylinders. As 'simple' as these engines seem, there was allot of German engineering that went into the design of all the components. The fan shroud was designed to work with those air hoses.

The attached images show the preload springs I was speaking about earlier in this thread.

The primary throttle linkage return spring runs from fan shroud to cable actuating arm on hex bar. Almost a straight line extension of the cable coming through the firewall. I also have two smaller return springs on each Weber, on each end of the throttle shaft, just to take up any slack.

Gordon,
I like a picture please and thankyou :)

Here you go, Mickey:

Pretty slick Gordon.

Mine just has a spring that hooks on the lower lip of the carb plate to the arm on the carb throttle shaft, (on each carb.)

The baby food jar covers work perfect then the crome tips to cover them up
