Short throttle springs

[markb]

For the #97 carbs I'm planning on using 28 tops, 5mm cables and short springs and slides.  I scored on a set of carbs that has everything I need except it was missing one of the springs.  Anyone have one they could sell me?  I think the part number is 16185-300-004.  There is a company in town who can make some for me but the minimum order is $300 so pretty much the same price for 1 or 25.  I just hate to spend $300 when I only need one.  So the other option would be if anyone needs/wants some I could have extras made.

Is that the spring CMS sells for € 2,50 ?

No. 35

#35 is a throttle stop screw spring.  i think Mark's looking for a thr.return spring; actually fits inside carb.l

[markb]

That's right Steve.  It's like #36 only shorter (approximately 114mm long).

keep asking around, Mark.  somebody should have a single 28 spring, i would think.  i used to have a couple extra, but i'm pretty sure i gave them away.  i'll look through my stuff, but i can't promise i've got one.

[markb]

A 28 spring!  That's a good name for them.  Thanks.

[markb]

I'm still looking for a 28 spring.  Anyone?

[markb]

If I decide to get some of these springs made does anyone else need some?

[Steve Swan]

Mark, i looked thru the few parts i have and i have none.  sorry.

Mark,

You can count me in for several sets. Just guessing, you can probably have 1000 made for the same price as 50.

Is anyone else interested in some?  Once I know the quantity I'll let everyone know the price and get some ordered.

Mark,
Count me in for several sets.
Thanks,
Duane

[Steve Swan]

sure, ccunt me in for a couple sets.

Looks like I've got a enough to get the price under $8 each.  Anyone else want any.  Might be able to shave a little more off the price.  Before I order I want to bring an actual spring for the manufacturer to look at.  Sor far I've just given them the exact dimensions and they said they could do it but I want them to confirm they can duplicate them before I place the order.  I'm going to try to get there this week and it would take 30 days.

I was about to place the order but after a couple of discussions with members I want to make sure I have the correct dimensions.  I've got one complete set and one set of three 28 springs.  The set of three has a free length of 112-115mm (they've been in the carbs sitting on a bench for probably 40 years).  The other set measures 125-130mm.  (By the way, they all had 15 coils and the wire diamter was .9mm).  Some later ones I have measure 140-145mm and have a wire diameter of 1mm and 22 coils.  One of the guys thinks the 28 springs were 20mm shorter than the later springs.  Some of all of these may have relaxed and are therefore shorter.
Does anyone know the original length of the 28 springs?  Or the difference in the length of the 28 and later springs?  Does anyone know the length of the later springs or have some they could measure?  Right now I'm thinking that somewhere around 125mm is close to the original 28 length but if they were a bit on the long side it probably wouldn't hurt.  Any input is appreciated.
