Hello, currently working on an old Remington sl-9. I found that the saw wasn’t picking up fuel, on closer inspection I found the carb has no actual fuel hose connection and the carb is mounted to the saw with the fuel inlet on the carb lined up with the gas tank outlet hole. The carb is a tillitson hs 107b my question is how can I pressure test this carb since there is no barbed connection for a hose?
