Why exactly is your carb dead? Are the gaskets shot? Is the float bad? Is it cracked, broken physically? Is the float bowl screw on stripped? The cheapest way to fix that carb may be to find out exactly what it needs and just get that from someone that is parting out a bike/carb, or rebuild the carb. Good luck. I used to have a parts carb for that model, but I think I tossed it..If I find it, I will let you know...
