O-rings are easy to find, I just go to a local hydraulic shop and they have all you'll ever need. As for the main jet and pilot jet, those are easy to replace, just find some that are the same size as the ones in your carburetor. The float needle and housing should be replaced, if you dig long enough you'll more than likely find some. In rare cases (like the one I'm struggling with) the jet needle will be wore and need to be replaced. I know there are some for sale for the 300 on Ebay right now. But if anyone knows where I can find a 5CHT40(A) needle at that would be great! I've been searching for a few hours, but cant find anything. Hope this helps you!
You won't find the proper sizes at a hydraulic shop. Most of the required sizes are very specialized.

You're probably right, I've only ever used Keyster kits that come with all the O-rings except for the fuel rails (In my experience). I then get the fuel rail O-rings from the hydraulic shop.
I like Keyster kits, but they do not come with all the O-rings. For example, they don't come with the O-rings for the vent Tee's, the drain screws, nor the pilot screws. I sometimes buy the cheapest Keyster kits I can find, but I only use the float bowl gaskets and the float valves. I do not use the jets unless the originals in the carbs are damaged. I'd much rather clean a real deal Mikuni jet, compared to using an aftermarket Keyster jet.
