Gentlemen, just s few questions about the amount of fuel that should emit from the pump. I had the fuel line off the carb and tried running the engine with what was in the float bowl. I have a squirt stop squirt action on the fuel pump. Not a steady stream of fuel. Which is more desirable? I pulled the fuel filter off as well and replaced with a new one. Same syptoms. Runs and vac ok for some time and then shuts down. Both mufflers replaced. New module. thanks for any ideas.
