What to do about fuel leak in sportsman 500?
Remove the carburetour and bottom bowl on it. Visit your local parts store they sell carb and part cleaner it comes in a gallon. Remove all rubber parts from the carburetour and soak in the cleaner for 30 minutes Make sure to remove the jets and letg them soak. I use a piece of wire to clean the jets out.
Why does the float bowl leak out of the CARB?
First it is an overflow, so that any time the float bowl gets too much fuel, it runs out onto the ground instead of filling the crankcase with fuel. Secondly it serves as a drain. Loosen the little screw there and it will drain all the fuel out of the carb. No they are not supposed to leak fuel. That indicates a problem.

What to do if gas is going into your crankcase?
It WILL NOT fix the problem. If the petcock isn’t shutting off the flow of fuel, it needs replaced but that still won’t fix whatever is allowing fuel into the engine. Pull the outlet line off the petcock to see if it will shut off the flow and then you’ll know for sure if it needs replaced.
Why is gas going into my crankcase / bad petcock?
But if the petcock is good and turned off when parked as it should be that shouldn’t happen. Any leaking through or around the needle valve or seat should just run out on the ground through the overflow if its not blocked.
