Stubborn Float Needle Seat

[Leland1]

So I start tearing down the carbs on the 650. Turns out the #3 carb has a fair amount of rust so I start disassembly on that one.


Well after a few hours of wrenching and gathering info here shes apart.... all except for the float needle seat. Ive hit it with a wire brush, WD40'd the hell out of it and heated with a lighter but it isnt budging. Whats my next step?

You could try this, or this

Maybe some penetrating oil, I've never used penetrating oil on a carb though, I'm sure you're placing the o-rings though

I would heat the general area with a butane torch then try and twist the offending part out with some multigrips. It is probably the old perished "O" rings that is gunk in there and sticking things together. If that does not work then boil the whole thing in a metal container of water for 15 mins or so to see if that will release it.

If all else fails you could cut a slot in it with a hacksaw and try and twist it out using a screwdriver. If that does not work then the last resort is to drill it out using a succession of drills going up one size at a time till you get within a 1/32" of the carb body, you should then be able to bend the remaining piece and pull it out.

Hope this helps.

Keep us posted.

Heat and penetrating oil are your friends here.

Very true, just remember that "lighter" and "WD-40" are NOT "heat and penetrating oil".

Use a propane torch and PB Blaster or Kroil.

Ok, I dunked it in Pine sol for 36 hrs. Still stuck. So I stuck it in the toaster oven for 5 min at 360 degrees and grabbed it with vice grips and twisted it on out. Ill need to replace it but thats better than having to drill and tap a new hole.
