I'm over in the UK i have just bought a 1980 Suzuki DT9.9 (Blue engine , red decals) bought as spares very cheaply as no spark bought a new CDI unit now runs first pull but the carb leaks out top after few minutes and it will not idle. tried cleaning out the carb and looks clean, it starts with easy start and runs on high revs as soon as they drop it dies, any suggestions would be great, one thing i did notice was that the nut holding the bowl on has a tube in it that has a slpit up the side is this right, i have a manual on order through amazon but its gonna be two weeks until i get it, any help most welcome.<br />thanks in advance
