Ok, so I was looking into the walbro carburetors for the motor bikes and information on them is very limited. Here's what I know that is baffling me. The walbro carb uses a diaphram and vaccuum to use as a pump for the gasoline/oil mixture. I've looked around and can't find anything regarding installing a vaccuum hose for this carb, so it makes me wonder if I even have to, or id I have to how would I go about doing so?
