Float Valve Seat on 85 70hp rude

[SCer]

I've got the real factory manual and am in the middle of a carb rebuild for my 85 evinrude 70hp (E70TLCO) with the trim/tilt. I've got the carbs disassembled except I can NOT get the float valve seat loose. It has a slot like a flat head screw and appears to have threads in the diagram, but I can't get it out. I've got a big screw driver but the thing wont budge on any of the three carbs! I even chipped a little bit off of one of the slots. Im guessing I can still stick a wire in there to clean it and soak it but the carb soaker Im using warns not to put any plastic/rubber in it. So now Im worried about the seal behind it if I soak it. Is there any trick I haven't seen on this website and the manual fails to mention? Should I soak them anyway with the float valve seat seal on it anyway? Any tips would be appreciated.
Also, one of the high orifices I cant remove from the bowl because it looks like half the slot on it chipped off (I cant get the screwdriver to seat), I dont think this would keep the orifice from working, correct?

You need the right size screw drive to remove the needle valve seat. You need to remove that for sure. The thing with the red lever is your primer, it shoots a squirt of gas in the carbs for starting, red lever parallel with the primer body. I too have the problem of one of my high speed jets being worn and i cannot remove it. What I did is stick a wire in there to clean it out and used gum out to spray it out as best as I could. It worked for me but I got some other carb bowls so i will probaly order the jet just for peace of mind.
