Walbro carb diaphram replace/priming
I have a Walbro carb WYl-161. I am relacing the diaphram. The one with the little spring in the back. should I be able to get a good prime - hooking up the fuel lines to the carb - without remounting the carb on the machine. I replaced both fuel lines and am pretty sure I have the upper and lower lines correct. I installed the carb and can't get a good prime - yes I switched the two fuel lines to make sure I didn't have them reversed. Is there a vacuum issue somewhere that I haven't thought of? Thanks for ideas..
