Aerox stage 6 cylinder head help?

hi just bought a new stage 6 streetrace 70cc kit as my old kit blew up but ive fitted it all on the new piston, rings etc etc but i have to use my old cylinder head because on top of where the temperature sensor and thermostat thing goes theres like two miniture holes which is water recycle system and water to warm the carb up but on my new 1 there is only 1 hole so if i connect my water to it im thinking it will go through to my engine my just straight out which means constant top ups is there anyway of doing it different as i need the new head on because the old 1 keeps leaking because my nut/bolt keeps falling out of the top left corner cause head gasket to as it did with my old kit? Thanks would appreciate the help, kieran

cratch: any chance of a picture of the problem, because im not 100% sure i know what your talking about....but

you dont have to run the water circuit for the carb heater if you dont want, i havent had the carb heater circuit on my last 2 carbs, its optional

You answered it already mate Thanks and some1 else previously helped me out but yeah that was alll i really needed to know was can i run the cylinder head off 1 water recycle hose or will i need 2 so i can warm carb up too but thanks :good:
