Hookin up a ys 91 4 stroke
Motor came with a one way check valve the instructions show go inline on the vent tube. Tryed that didn't work to well. Puttin fuel in air has to vent somewhere so it picked the fuseloge along with the fuel. What a mess. First time with ys motor someone explain the system, or just remember to unhook checkvalve before putting fuel in.
Thanks, Charlie
