How to remove carb float pins?

What's the proper way remove the float pins on FJ1200 carbs? How hard are they to push out? I'm afraid I might break the aluminum towers that hold the pins if I push very hard.

The float hinge pins appear to be pressed in. That is, they don't just slide out like other (automotive) float pins. I'm afraid to push on them because the slender aluminum holders look like they could easily break. Should I use pliers to pull them out, or what?

thanks.

Usually not hard, you can use a finishing nail to tap it through.  Once they get moving they come on out.  One side of the pin might be more peened than the other so if it doesn't want to go one way try the other.  Definitely take it easy and don't break those castings

You should be able to lightly tap the float pins out.  If they are stuck because of old dried fuel crud, try spraying them with carb cleaner to help break them loose. 

Yes, the float posts will snap off if you use too much force.  That's usually a bad thing.  Once you get the pins out, take some 600 grit and sand them down a bit on each end where they fit into the float post until they fit just a little looser than stock.  I always do this to every set of carbs I work on.  If you look at the shape of the float bowl, the float pin is in a slight recess in the bowl.  This recess will prevent the pin from falling out.  If it's too loose, the pin may back out some, but the float bowl recess will keep it from falling all the way out.

It's good to have smart people on here, or at least ones that can bluff well :rofl:

Thanks dd,

I'll tap on the end of the pins a little a see what gives. Hopefully it will be the pins and not the cast aluminum.

My pins have a head like a nail on one end. Obviously they only come out one way.

I just want to be sure the pins are pressed in and not threaded, crimped, staked, or something unusual like that.

thanks again.
