Carb rebuild had to replace primer pump due to corrosion. So on the float bowl what supplies fuel to the primer bulb. The main passage is clear but when I fill the bowl with fluid the primer pump is not drawing fluid from the bowl. It appears some other passage is blocked.

when you had the primer off did you clean the passage behind it , is fuel coming outthe fuel hose from the petcock ? I have a 450 and the fuel hose has to be down as far as it can go or the fuel doesn't flow well from the tank and if you cram a fuel filter in between the carb and petcock it can stop the flow as the hose is too high , or even if you don't have a fuel filter but have too much hose and it loops upwards it will slow the flow , make any sense

yes, there is a passage that leads from the float bowl to the primer bulb, you will need to remove the primer bulb, and try to clear it. thing is, unless your living in zero temps ?, I hardly ever use, much less see any one use this primer bulb.
