Hazmat, I'm just a little confused. Item 11 in the first view looks like the fitting that the fuel hose clamps on. Item 10 would be the float needle seat. The second picture gives you a technique for removing the float needle seat (the press in type). Both types of seats were used and I would think that if you have the proper carb kit you should have the proper seat or both seats, some carb kits cover several different model carbs. You may want to compare the other parts in the kit to what you have. As far as cleanig the carbon, I like to use one of those flimsy little "giveaway" pocket rulers. You can use the round end and the flat end as a scraper to get the heavy stuff off. Then I use a wire brush and carb clean to clean it up nice. Just remember you are working with aluminum and it gouges easy. Nothing wrong with using a "motorized" wire brush either as long as your careful not to remove too much aluminum in the process, you just have to be gentle. Don't clean the gasket surface like this, the best way to do that is scrape off any heavy stuff. Then if you have an old peice of glass laying around or a flat machined surface you can clean it up by rubbing on a piece of 400 grit wet and dry paper keep it wet and clean with carb clean. Just lay the paper on your flat surface and "sand" the head in a circular motion. And like Ron just said, if the seat was'nt leaking you can blow off that step. Just shoot some carb clean through the old one and use the new needle valve. By the way item 9 is the needle valve.
