Where to find stainless needle valve plates?

My friend bought a ski that had been sitting for a while and after noticing that it was running bad he pulled his carbs apart. Many of the steel parts were significantly rusted. He has located most of the hardware in stainless but neither of us could find a needle valve plate in stainless form, just regular steel. He would like to find a stainless one if possible. Where can he buy one? I attached a picture of the parts diagram. The part we are talking about is labeled number 42, in case it goes by a more common name. If there isn't a place to buy one he is thinking about having some made and selling the remainder of the lot to cover the costs. He would like to know if there be interest in some if he were to order a batch to be made from a local shop? What do you guys think? Just loaded another pic of his after he blasted it. You can see where the rust was.

That's what we figured. I mean the only reason it rusted was because it was neglected and sat unwinterized for years. Under normal circumstances we realize they wont rust, but sometimes people just like having higher quality parts, even if its unnecessary lol. Thanks for the input everyone. I'll pass along the responses to him.

^^ what he said. That is one reason why 91 octane MTBE fuel is critical as well. E85 or just regular 87 & 89 contains ethanol...or as painters know it, paint thinner. Have you ever seen the filters in a carb with what looks to be full of hair? That is actually fibers breaking down in the fuel lines and/or tank and being passed into the carb. The gray Tempo fuel lines that BRP used to use in the late 90's on their couches were high susceptible to breaking down when ethanol was introduced. The skis found a tendency to blowing up...not only in general lol...but because of lean fuel conditions due to partially plugged carb filters. The only cure to the issues with the fuel lines was to simply replace them with ethanol resistant lines, or if you are like me when I had my 96 xp800, the best cure was to get it the heck out of your life as fast as possible lol. But if the people in the area knew how *cough*"good"*cough* they were, you might have a very hard time selling it...that is when plan B comes into play, it's not cheap, it's not clean but would be sooo satisfying and fun! (see the link below) ;)

Indeed but as mentioned the old Tempo lines failed when ethanol was introduced. That being said, it also means that some people do still use 87 in their skis. But there are some instances where ethanol has been creeping its way into 91 octane too. You ever notice on the pumps they used to say only on 87 and 89 "may contain up to x% of ethanol", and now it just says that on the pump regardless of grade. Very few places have guaranteed MTBE 91 anymore. I like to think that the site listed below is reliable, because it really is getting to be rare blend nowadays.

I know from experience that a ski left sitting with gas still in the lines, will rust out the Steel parts. Lucky your Friend was able to remove the Screws, has not been my experience. the screw heads just break off. And Keihin Carbs, you put questionable gas in let it sit for a month. Just accept that you will be tearing them apart and cleaning at the very minimum. Damn Viscose(or whatever its called) will rot away. Good luck, the Gas today just sucks, in a lot of ways.
