Thanks for replying. Good question about the manual. It's a Clymer. The carb has 3 hoses I can see with a diaphragm on top. There is a small aluminum Mikuni component with 3 hoses attached. It's about 2.5x1.5x.5 inches. One hose goes to the fuel petcock, 1 to what I think is the engine vacuum and the other to the carb? The fuel pump maybe?

I'll see if I can find a genuine service manual. Do you know where to find one?

I’m trying to repair rodent hose damage to my  1990 king quad 250. Several hoses to the carb were destroyed. I’m going to replace them. The manual doesn’t provide a layout or description of what they do or where the hoses go. Does anyone know where I can find that info?
