Hi. I'm having some MORE trouble with my blaster. I think that it is a carb problem. I have the 28mm oko carb, whick is basically the PWK carb because it came with a Keihin book. With my mods listed in my signature below, I'm running a 42 pilot jet and a 148 main jet. Whats happening is that the quad is hard to start(unless it's been sitting for over a half hour with the gas off) and when it runs, it bogs out unless I pin it, then it jumps, but if I let off the throttle, it starts to die. If I juice it after I hear it starting to die, it jumps up again, but it only does this for a while until it dies and won't start again. I adjusted the float hight to 19mm (this is what it says to do in the book) and when I do, it slowly leaks out of the overflow on the bottom of the carb.It only does that if I kick it over, or when it's running. I don't notice it dripping as fast if it's just sitting. I tried lowering the float and it stops dripping even when it runs, but it does the same thing when it is running. I took the carb apart and cleaned everything meticulously. The reeds seal up good, and I have good spark also. I need to get this thing running before this saturday, and I am getting really frustrated. Any input would be greatly appreciated. Thanks
 
turn the tube up so no ,gas comes out thats all i did and it stop and i ran it for a while and then flipped it down and it didnt leak or check the screw in the botom of the bowl where the hoose comes out
 
It sounds like the float is sticking, or the float needle isn't sealing completely, or you have a venting problem. WTH is an OKO? Is that a chinese knock-off or something?

Yeah, it's an OKO. The needle sealed real well in there, but it may bave been stuck in the down position when it was running. It felt a little sticky, but the seat looked fine.
