On a related note the o ring under the seat...what is it's purpose and how do u know if it's good? I'm guessing it's to stop fuel from entering the space around the valve seat...assuring that fuel enters into the seat first. I'm further guessing that with the needle installed that if u blow through the fuel inlet and no air is moved then the o ring is good but I may be totally wrong so if u can advise on this that would be great.

I would say use the Q-tip trick that was suggested and do a good cleaning job on the seat without removing it. If the WD-40 doesn't get it done, then use spray carb cleaner on the Q-tip. Once you're done screwing around with the needle valve, you can start working on that pilot circuit. If this is how bad your inlet circuit is, the pilot circuit is more than likely just as big a mess and will probably lead to your next thread.
A word of advice on the spray carb cleaner. It will attack all your rubber parts and can ruin them. There's quite a few rubber parts, the bowl seal, air horn seal, fuel screw o-ring, AP diaphfam, etc. There is also a rubber seal on the slide plate and when you start the cleaning task on the pilot circuit the passage shoots right under the slide and the spray cleaner is going to hit that seal. If you don't want to remove the slide, then make sure you open the slide and stuff a rag between the slide and the pilot passage hole while cleaning.

Unrelated question....I removed the TPS from the carb. Is there a special way to put it back on? only reason I ask is because on TokyoMods carb form it says DO NOT REMOVE TPS FROM CARB....so im wondering if there is a reason. I'm not sending my carb to them I just know they have been in the game a while.
Thanks. Happy New Year to everyone!!!
