See page 5.6 in the manual above. Do you see it? Not the seal on the throttle shaft?
Fuel inlet seat is a squarish o'ring that goes in the upper passage for an all metal needle, it is not used in model with a rubber tipped needle.
O'ring would go in the upper passage , where all metal needle valve would seat on it. It has to be tight in the upper housing, so it does not fall out.
Ithas to bottom out in the passage, Use a drill bit end or a wooden dowel to seat it.
One will fit the opening better, you want it close, but has to be loose. The one on the right or the center one , either will work with the upper seat.
Did it have one before? Just pinch the seal and slip it into the passage, then straighten it up and push it in.
If it has an all metal needle and not the rubber tipped needle, it has to have the upper seat.
You got it bottomed out? You have the needle installed correctly in the float, where float holds needle and needle not on the top of the tab? The fork on the float has to hold the needle by the groove in the top of it.
OK< and the needle is all metal and has no rubber tip? What happened to the original, as it has no tip?
Ok, then you use it less the seat!
Yes, I'm here
I never left, Not sure why your response just now popped up!
I see question is still open, did you get the needle worked out?
