does the engine lope and run rough at first? does it blow black smoke out the exhaust? if yes i think the carb is draining itself into the intake manifold over nite and flooding the engine, if the answer is no then i think the suction valve in the fuel pump is bad and not sealing and letting the gas from the needle and seat all the way back thru the fuel pump drain to the tank, turn over that disk , the suction disk, its a hard round plastic looking thingwith a little spring on top of it and it may stop, or buy a rebuild kit or new pump, the inline fuel check valve is just a micky mouse fix, fix it right
