It will be the needle valve, the rubber tipped valve that slides into the float.

Clean the valve seat thoroughly and replace the valve for OEM or Shindy.

Make sure the tank, petcock and inside of hoses are very clean , all it takes is one piece of crude to stick the needle valve -------------- add a in-line filter screen ------------------- take the carb apart . use tooth paste on a Q-tip and polish inside the seat of the needle valve , then clean out the tooth paste really well with some carb cleaner and compressed air

Yeah that's what I ment I cleaned the entire thing and replaced the needle so idk what it could be
That's all it can be.. It's NOT clean, can't be..!

Carbs have to be surgically clean. I've just rebuilt a 1988 300 fourtrax carb for a friend of mine, cleaned it 8 times in the end before it ran as it should.

As I always say... If it looks clean, it probably isn't, so clean it again.

Is the carb OEM or Amazon/eBay China junk?

ONLY use OEM.. You'll forever be chasing issues with China junk.

How have you cleaned the carb? Used carb cleaner and left it to soak for a few days? Tried boiling in lemon juice? Rebuild kit is OEM or Shindy?

I assume the fuel tank is spotless and free of rust and any debris? I so assume you have an inline fuel filter fitted in the fuel line?

It's the oem carb got the needle directly from the Honda dealer talked to him and he said it's just because they sit for to long there needles go bad so I fixed it and cleaned every inch of the carb and yeah I've got the inline fuel filter

The valve seat where said needle sits can't be clean then. It needs polishing, a cotton bud with toothpaste or very fine abrasive will do it.

That's the issue, and the cure buddy. Ask on other forums ;-)

Best of luck.

Okay thanks if it continues to leak I'll have to do that but when I put rancher away it wasnt leaking
But , It is leaking now !!!! ----- Try adding about 4 ounces of Sea Foam to a full tank of fuel ---- you need to check your oil often when you have a carb overflowing , cause it can overflow and go into the cylinder and do two things , one is wash the oil off the rings and cause premature cylinder wall wear and two , once past the rings , mix with the oil and thin it out

I've ran it for about a month but before it wasn't run for about 9 years no rust or anything it's been in a garage first thing I did was put in seafoam and new oil filter and oil but my dad's a mechanic and said hes never changed the oil before which is hard to believe lol it came out like a grey water consistency
