I finally took apart my new PWK 40 carburetor. I am starting to understand why it was so inexpensive. Float bowl sealing surface is pretty rough imho. There seamed to be a micro thin layer of rtv on it even though the bowl has a o-ring. None of the jets have any identifying markings on them. The needle has no markings, either. Time for all the pics...

Thanks for the pics Sneezy. As far as I can tell, yours is pretty much a carbon copy of mine. With the exception of the absence of a notch in the needle jet hood and the absence of markings on the jets, it looks the same as mine in every respect.

No sweat on the jet markings, you won't be using them anyway.

You mentioned there is no washer under the needle clip. That is how it's supposed to be. Don't try to put a washer under that clip. If you do, you will wreck the clip.

Don't ya love that cheap plastic idle stop. I think we need to be careful with that. I bought a metal replacement, but I noticed that the parts list shows a plastic idle stop for chrome plated slides, and a metal idle stop for non-chrome plated. I'm leaving the plastic stop screw in place. I have to screw it waaaaay in to achieve my preferred idle speed (1400), but I don't want to be chipping chrome and causing a sticky slide. Always better safe than sorry.

Years ago I had an idle stop screw break off on a VM. It was installed on a little Yamaha YZ100. That chunk of stop screw went through the reed valves and into the engine. Ruined the whole darned thing. That can't happen on the PWK, but fragments of chrome can get chipped off and get between the slide and carb body.

I was thinking of taking an exacto knife and trimming off that flashing making the taper end where it should. It is not an even piece of the part design. The slide has a lot of small nodules in the plating. Bot smooth on the curved side. Real poor plating quality. I had a lot of dealings with metal plating shops during my career. Not hard to recognize poor quality in that regard. I hope it doesn't start to peel or blister anywhere.
