Does the carb have a brass drain screw?

I know the 500 does,

Would suggest you unscrew it, and see if fuel runs out

Yup, it sure does. You see the big brass screw at the bottom of the float bowl? That's it!

Ok - so the carbs are out at the moment....yesh - see the screw at the bottom of the float bowl....without putting it all back together yes the float bowl was filling up as the overflow pipe was leaking...what next!?

Edit - well i got it working....ive kinda got an idea of what it was but it may not be....

took the float bowl off (3rd time) took that little jet out behind the float bowl the long one with the two holes in it - but this time put a very thin bit of wire down there.....it didnt go all the way through (im not sure if it should or, shouldnt) and then re-assembled...i did also the other day add in the fuel additive stuff so not sure if that helped....

Anyway it started really quickly....literally a push and instant start...most responsive yet. Next would be for one of you guys (who ive met) just to listen to see if its needs further fettling!

Thanks to everyone that chipped in!
