Carby leaking
I have an old 86 trx250 fourtrax that I have been restoring. The other day I cleaned the carburator out but didnt take anything much apart. When i put it back in and turned on the fuel it all came pissing out of the overflow valve and wouldn't stop. Any help is appreciated.

Your carb has a lot of corrosion on it and probably some inside as well. At least I can see some gunk in there just from the pics. Due to age and condition visible in your pics, I would guess the float is sticking or the float valve is just shot. Time for a complete rebuild from the ground up or perhaps due to the condition of your carb a new one might be in order. Pictures make it look like she has endured some excess time outdoors in the weather.

If you disturb the carb it will often start leaking fuel from the overflow, this is simply some dirt from the pipe or tank which got dislodged and is now stuck to the float needle. Sometimes, if you just turn the tap off and run the bike until the float chamber is empty, when you turn the tap on again it flushes the grit out, and you are good to go. If that doesn't work, you have to remove the float chamber and float, and clean the needle, blowing out the seat with compressed air. You may as well blow the jets out while you have access to them too.
