Leaking Out Overflow While running

[CrashB]

Hello everyone first would like to say I love the forums lots of great info. Now second I have a question and know someone here can help me out. Ok here goes, my carbs used to leak out the overflow while the banshee was not running and stop leaking when running, it ended up being the needle valve was worn. After the rebuild and some airscrew adjustments it ran GREAT that night, when I got back home I noticed gas was leaking out the overflow while it was running but when I shut the engine down it stops leaking. So basically the total opposite of what it was doing b4 the rebuild. Any ideas as to what could this would be great, thanks. And both problems are occurring only on the 1 carb not both.

With any scenario where the carbs dumb from the overflows, that is a needle/seat issue. The Banshee has a very poor fuel filter that allow contaminates through. Install an inline filter as well as clean the carbs and start there.

if youve taken the carbs apart several times, you couldve accidentally changed the float height and not even realize it.

 

if your needles and seats are in good shape and theres nothing lodged in the carbs, chances are youve got a float height issue.

Thanks to both for the help, I will look into both solutions, is there an official way to check float levels (just by eye, make them level upside down?) blow into them? Not to sure.

Also what’s a good oil/gas mixture for a mostly factory quad with amsoil, is 32:1 normal. And every other toy I ever owned I used br8es but this banshee wants br9es which should I use? I am going to list a couple questions below any help would be great. I am very new to this so I really appreciate the tips from experienced riders.

 

Average position to start testing Air Fuel Mixture?

Needle Clip position

Air Filter Bag On or Off?

Spark Plugs?

Gas Mixture?

 

Banshee Specs…..

Mostly Stock Banshee

FMF Gold Series Pipes.

K&N Air Filter

Amsoil

I think I’m at 800 feet above sea level

Ahh that’s all I know.

Sorry and if only 1 carb leaks i should only take apart that 1 carb correct and leave the other alone?
