The pin that the float pivots on in my 3hp briggs carb is stuck. Anybody know a trick to freeing them up.I am very careful now , but I broke a carburator trying to get one out before. Thanks

Ho boy, you are in for a fight now, soaking in penitrating fluids for few hours, if nothing then a few days seems to help, every once in a while go back and push it back and forth until it begins to move.

Soaking in electro chem bath seems to help a lot too. Aluminum and steel loves each other, had to break a long term bond.

Do not use open flame or torch, the pot metal carb will melt.

Best of luck.

Is the float any good? 

 

Usually if the float pin is that messed up for me at least, the float is too.  I will many times cut the float off if it is full of vintage gasoline and then wiggle the pin back and forth.

 

Briggs was bad about not giving much clearance on the float pin.  Most of the other manufacturers would make it loose enough that their pins actually fall out if the bowl was removed.

I got it out. The  float seems good. The gasket above the float is broken, it is now anyway, so I will try to get a new gasket tomorrow and reassemble the carb. There is a tractor dealer near here that seems to have a lot of older , obsolete Briggs parts left so I think he will have the gasket or a carb kit. Thanks.

Glad you got it out.  I also use Penetrating fluid usually PB blaster and a small hammer and start tapping it on way and tap it back.
