Problems with flooding occur when your float valve in the carb sticks or when you got leaking floats. Those are your last lines of defense against unmetered and continuous flow out of your airbox and/or down the cylinder walls and into the crankcase. Best bet is to always turn off the raptor petcock. That being said...I never do. THAT being said...i'll be MIGHTY PO'd when/if I ever have a stuck float valve.

ok so something very ironic just happened...as i was typing on here about turning my petcock off and flooding and stuff, i went out to get something from my storage closet and smelled gas. sure enough i left my fuel on and it is leaking out of the hose that comes out of the airbox so.......i guess you were right and my carb is jacked up.....arghhh!

what is my next step here? pull the carb and look at what?

You could just rap the side of the float bowl a few times with a screwdriver handle, but for a permanent fix, you'll most likely need to pull to carb and change out the needle valve and its seat. Good luck!

You probably have all the answers above, but.......
it is best and safest to turn a Raptor (normal) petcock off after each ride,.....same as the stock vacuum valve does automatically, but you shouldn't have to ! If you do have to turn it off to keep from flooding, you really need to get it fixed, which means cleaning or replacing the needle and seat in the carb.

Needle and seat is an old term for needle valve assembly. It consists of 2 parts (needle & seat) that actually seal the fuel from flowing. It may also contain washers and possibly a clip that pulls the needle down as the float lowers.
I myself have not been into this part of the carb, so don't quote me for every word Wink

The needle and seat are sold as a pair #19. There's also an o-ring #21 and a little screen that also clips on the seat #20. You need at least the needle and seat. May be able to use the O-ring and screen off your old one. To be sure I'd get the o-ring also though.

Here's a couple kits on ebay that'll have what you need for a little less.

The second one has everything you need and it's a little cheaper. The first one has got some extra stuff you might need down the road someday as well as a new screen.

Well... I'll give you a quick explanation of how the needle and seat works. Not sure if there are other threads that explain everything.

The gas flows from the petcock to the passageway directly to the top side of the seat. When the carb is empty the float is down pulling the needle with it opening the passageway for a freeflow of gas into the bowl. As the bowl fills with gas the float rises closing the seat off slowly untill it reaches the top closing the gas off completely. As you run the bike it uses gas out of the bowl and the float drops opening the needle and seat and letting more fuel in as needed.

There you go. Thats about the most basic explanation as I could think of. Hope that helps.

You might try emailing them and see if they'd throw a couple larger jets in with it. Looks like they sell a lot of carb kits. Might be worth a try. They might possibly take out the smaller ones and repalce them with the jets of your choice. Won't hurt to try. Good luck
