Fastest, easiest carb clean. Johnson 70hp 1980s
Old fuel will evaporate over winter and thick oil and varnish will be left behind. Gravity will pull this into the bottom jet as it is the lowest point of the carburetor. 99% issues with these engines are caused by this.
To prevent your floats from cloging with oil etc over winter you should disconnect your main fuel line while you flush your engine after its last use. This will empty the fuel lines to your fuel pump and up to your carburetors. I don't recommend running your engine out of fuel as different carbs may run out at different times. If one cylinder stops getting fuel while the others keep the engine ticking over you won't be getting oil to the cylinder with the dry carb. Just run the engine for a few seconds to clear the lines up to your carburetors then shut the engine off and drain the carbs from the drain plugs.

You would definitely NOT be the first one to have done that. That would be a long list.
That's where the dad gummed things are hiding. Thanks dude.

Indeed. In this instance I was more concerned with removing a blockage on the fly. Get the motor running without removing the carb to get someone home.
Nice video, thanks for posting! I have a question.. Do you know, is the screw at the top..in front of the idle air jet supposed to be tight. or 1 1/4 from seated?

Howard Mora. Can't really say sorry. There are so many different versions. Including year and hp etc. On saying that carburetors often have the same general functions so it should at least be similar. The common issues are crap blocking jets or a float issue.
