I just did a valve adjustment on my 2008 Roketa MC 250B ,with only 1300 miles on it-and while taking the plastic off,I noticed this little part --just attached to the frame--looks kike it should have a hose attached and it seems to have an adjuster screw in the other end--surely ,it must be something someone knows about--I looked in the Roketa parts list and I can't seem to locate it- the scoots runs great as is--just wondered what the heck it is? fflintstone

That is the CARB Bowl Drain. I would say someone has modified the hose coming from the bottom of the bowl and just left that hanging.

Yep that's where the drain hose from the bottom of carb should be attached to

Fflintstone, they are correct. look at the bottom of ur carb bowl and you should see a small hose the dia of a vac hose running from there down thru the frame and hooking on to one end of valve. It usually has the wire hose protector on it. The screw on the other end simply unscrews and lets the carb drain out so you can service carb or for winter storage. It adjust nothing. Just hook it back up for future use and make sure that screw always stay tight. If you loose it when u crank engine gas will go straight thru carb and the engine will not start. I always open that, drain carb for winter storage, that way the needle valve wont stick in the closed position when u try and restart in spring. It works great. Barnie

Thanks damin69,richardthescooter and Barnie---I looked in the Roketa Parts diagram and couldn't locate it--also,I can't find a hose anywhere hanging ,so the guy that had it probably lost it--scoot runs great --now I will just find a hose and install it since you guys identified it---now I got to do a valve job on my silver 250 B--it got almost 5000 on it so it is due--thanks again,all,happy trails,fflintstone

Fflintstone, since the engine runs great the person that had it before you has the drain plugged with something, a short pc of hose with a plug in it of somekind other wise the gas would go straight thru it. A pc of vacumn hose will work just fine as it is simply a drain for when u need it. The outlet on carb will be just a little burb on the carb bowl itself just below where your fuel line comes in. I am assuming you have the linhai 257 engine. Glad we culd help you. Barnie

Here's what the complete assembly looks like:

Ah---thanks Barnie and cruiser---I have had a 250 B since 2008 and didn't even know it had a gadget like this--learn something every day--I guess I better look at the carb and see what is going on with it--thanks again everyone,happy trails,ride safe,fflintstone
