"ATV carburator issue"

I have a 2002 Yamaha 660 Grizzly. I rebuilt the carb due to running poorly, after re-installation the Griz started fine and ran great. After a few minutes it started stalling and fuel was pouring out of the overflow tube in the float bowl. I rebuilt the carb after buying a new one and it having the same issue. Im assuming the needle is not seating properly so I adjusted the float level, same issue. The only thing I can think of now is there is debris in my fuel tank which plug to inlet so the needle doesn't seat properly. I have posted this on some ATV forums which didn't really help, hopefully someone on here has an idea.

Thanks,
Dirty

Can you put an inline fuel filter in and rebuild again?

I ordered one today. I am going to wash out the fuel tank and pour the gas through some cheese cloth to see if there is debris in there. Been jacking with it for a couple months. Tired of carb issues, may just buy a new one soon.

F'N JAP Built YAMAHAMMERS!

Seen a few Things cause problems on that Machine!

One of them had never had the Valve Turned to 'RESERVE' for several years!

All the BS/Dirt accumultated in the bottom part of the Fuel Tank & when it finally was turned to reserve it Filled the Carb with all kinds of BS!

Take that Tank off & Make sure it is Clean/Spotless!

Also:

The ON/OFF/RESERVE Valve on that Machine is Famous for small pieces of Rubber breaking off when it's Turned & the Debris ends up in the needle valve/Needle & Seat in the Carb!

Rule # 1 when working on a Yamaha:

Squint them eyes!


Back Me Off to 1,700 Yards,650 is a Little Close & I'm Not Comfortable with it!

A GUT SHOT at 1,700 Yards will Still Make Some Good BRAGGIN Rights so I Can Say I At Least Hit Him!
