fcr 41 flooding problem

tell me o knowledgeable ones...
i have a fcr41 mk1 on my old 01 fe650.
i have always had trouble starting the thing when it has been flooded,for instance if i layed the bike over on the side of a hill.
starts not a problem,1st kick hot or cold,but flooded not a hope of getting the thing going, in any less than 40-50 kicks.
on my old xr600,all i use to do when it was flooded, was kick it through 1/2 a dozen times with the manual decomp in while holding the throttle wide open , then next kick it would start.this old girl just wouldn't clear itself.
take a look at these pics of my fcr,i'm thinking there should be an overflow outlet on each side of the carb at where i am pointing with the zip tie,cause there ain't none on it.
what cha recon?
..weed..

thats strang?
yep,i replaced the needle & seat & o-ring that seals the seat to body of the carb less than a year ago.thats all good.float level is set to what the kehin manual says, that is shut off at 11mm below ,from where the bowl bolts on to the main carb body.thats always worked fine for me,as long as i don't lay the thing over.
so i'm taking it all kehin fcr41 mk1's has no carb overflow.
if the needle & seat sticks it just pours straight down the intake flooding the engine?
it has nowhere else to go... so it has to.
like husabutt just said with his 05 model being a mk2 fcr41,thats what the overflow is for,at least its pouring out on the ground until the carby is tapped (to unstick the needle).
think i better have a good look at a mk2 fcr.
i can't believe knowone else has this problem with the mk1.
then again i've always been a bit different.
maybe you blokes never come off??

thanks for responses lads.
although i do hear you on the different float levels,i have tried different heights in the past & still do believe that isn't the problem.
i think these fcr41 carbys are made to bolt on to dirt bikes as well as roadies.
i think ,as far as i can see,probably the only difference between a road bike fcr & a dirt bike fcr would be the fuel bowl.
the carby that i have would not be a problem on a road bike,cause they don't get layed over,as dirt bikes occasionly do.
knowing the price of kehin parts i think i might drill & tap fittings into where i was originally thinking.if it don't work i will just have to put a plug in & buy a different fuel bowl.
yeah, the vent tubes was the 1st check i done,they were all good,there is 2 of them,little brass fittings,one either side of the carb,up near the "k"for kehin.
