If it makes you feel any better, I have been squirting gas and oil into carburetors for probably almost 50 years and have never had an incident. Reed valves make it pretty unlikely that you will have a blow back. I didn’t make the technique up. It was taught to us by OMC. In small boats where I can both steer and reach the carb, I do it without assistance. Frank has been around longer than I have and has worked on those big old fuel black holes more than me. I am not disagreeing if he says it’s linkage. All I am saying is that the fuel spray test will eliminate any doubt you might have left about fuel supply.
Long live American manufacturing!
