Installing Mikuni TM34

I've been a loyal Amal supporter, but have had enough. I'm going the Mik route. I noticed that my new carb has a very long slide spring, so long it buckles when compressed. The length makes it nearly impossible to compress to fit the cable to the slide. I am attaching a picture of the spring, does this look right to you guys? It appears to be much stronger than is required.
Tnx,
Jaydee

I think it is a bit optimistic to say you will need to do this only one time.

After 4 or 6 times it will get easier. After 20 or 30 time it will become second nature.
The length of the spring may have grown over time due to complaints of sticky slides. I have even pulled mine apart even further because I could. If it seem too strong, then that is good. The slides are said to stick not because of the fit, but because of the draw of air flowing past it. At least that is what they say. I never had an issue.

Use it as is, they are all like that. You should try holding THREE open for 8-10 hours with only your thumb...

That's the correct spring.

Something doesn't seem right about your description. Trying to rack my brain a bit here, as I put a TM on my 850 a year or so ago.

It may be that I put the carb end of the cable on first, as it was a new cable. If you get maximum slack in the cable you can get it together and then pull on the cable to compress it. I think you have to hold the spring and guide it a little, but it shouldn't be too difficult.

Then hook up the other end...hopefully you have a cable with the adjuster in the middle...that lets you slack up the cable to get the extra length to get it in the twist grip.

I might be all wet about this, but I think that is what I did.

I use VM34 and have the spring doubled with another to cause twist grip to return reliably

I had my VM34 stick when I went full throttle after first installing it in place of the Amals.
Glad I had my kill switch.
After that no sticking at lower throttle settings.
Others on this forum agreed it was a common problem and suggested adding an Amal spring.
So now I have two springs, no sticking and throttle feel no too stiff.
