Weber Throttle return Spring comes out.....

[pharriso]

I have the standard airbox with Webers on my Elan. The throttle return spring engages one end in a bracket off the airbox & at the other through one of the Weber throttle levers like:

Throttle cable not shown...

Over time the return spring keeps on working part way out of the hole in the throttle lever until it is cocked & only through the first hole. The side of the spring then rubs against the carburetor body & the throttle does not close properly.

Anyone have a way to stop the spring from working it's way out?

Would a starlock washer be a good solution:

3/32" would be good on the .103" wire

The spring material is too strong to bend after assembly... maybe a tie wrap?...

if you can find a starwasher small enough that would do.

in my mini days I had similar issue and so stripped the plastic of a single electrical choc block and used the screw clamp to secure the block to the spring.

I just put a slight bend in the end of the spring. Not so much that you cant push it through the two holes with a bit of steering but enough to stop it coming out again.

I threaded the length of spring that protrudes and put a nylock nut on. Sorry, I cannot remember the thread spec.

Similar to Dave, I used a Marr electrical connector brass inner part (set screw type.) Tried the bending the wire trick but aside from being stiff, is a pain if (when) you want to remove the carbs. When I had the 151 carbs on with the extra boss on the side the spring backed out a bit and fouled the boss causing the throttle to stick open. I like the threading and nut idea.

Herb, I'm thinking probably 4-40 UNC... My return spring is .103" OD & 4-40 is .112/.095/.0805" Major/Pitch/Minor diameter. Let me see if Lowes has 3/32" push nuts or 4-40 UNC Nylocs.

Phil, I am not sure what an elec. chocolate block is, I was referring to a household electrical connector produced by Marr, that are readily available I would think, I am in Canada so most of that stuff is common with the US.
I could mail you one if needed, they are cheaper than the stamp

I think the term chocolate is the common English name for:

Thanks for your kind offer, I'm going to Lowes this evening, let me see if they do them, or if they look at me like a Martian (like they do when I ask about Taps, Torches or Hose pipes...)

It's nice to have options!

Marr conn. below, ask while at Lowe's .
Or if you know a kid with a mecanno set purloin one of the brass shaft clamps.

I cut off the inner end of a brass UK domestic electrical pin complete with its screw. This fixes on the free end of the spring spigot. Works well. Similar to the chocbox connector above.

A neat solution would be to drill a hole at the end and install one of these but the metal might be too small.
If it works, however, be sure to use a washer between the clip and throttle piece.

OK, another way to skin the cat: assuming you have 1/4" or so of protruding throttle return spring and can't find a suitable starlock washer, how about purchasing a small spring that fits tightly over the return spring? Essentially, a tiny version of the spring collar in the picture below. I think this would work better than a tie wrap.

Well this is my first attempt as starlock's haven't arrived yet:

Half a chocolate block insert...

Way too small for one of these Greg, but you might get away with a small hole, say .040" or less & safety wire.

OK... Starlock fasteners arrived this morning... perfect!
