620 gas carb leak

[Anonymous-0]

I just replaced the gasket on the carb bowl but gas still leaks. I can't seem to turn it right to get it to stop leaking. Would gasket sealing be the answer? If so, what kind. Any help would be appreciated. This on a 620 Deere.

BE CAREFUL you don't bust that stem trying to tighten it up !!!!

There is an o-ring on the center adjusting screw that could be leaking too. Check fuel level so it is not going over full.

And the sealing washer for the center stem nut goes on the inside of the bowl and not the outside. I see this done wrong ALOT. I like to lay that tin bowl on a flat steel plate and then use a large flat punch to straighten them out where they got drawed up in before. I also use a very thin coating of non-hardening permetex on both sides of that gasket washer as they are hard and this helps seal imperfections. AND don't draw it up really tight !! They will break !

Do not find out the hard way what happens when you tighten it too tight.
