How to Clean Carburetor 1968 9.5 HP Johnson MQ-14D

[@guyunknown1311]

Thanks a mill Mike, watched this video 4 times, got the courage, and rebuilt my carb on my 1972 johnson 9.5 Runs amazing now!

Another great job T mike I can’t get enough of the vintage outbords I am 61 years old grew up on the Kankakee River it runs through northern part of Indiana and Illinois seen all those outbords we had a 25 hp Evinrude about a1970 I think it was

Do you have a video on how to trouble shoot a choke that will not stay closed and as a result makes starting a sometimes tricky operation? I looked but I do not see one with that in the title. I have a1990 Johnson 6hp that I bought new, and it still runs great. However, I am having trouble now starting the engine because it is starved for fuel on a cold start. After running, no problem. I think the culprit is the choke because it will not stay closed once I pull on the starter rope. It needs to be finessed, but it will start eventually. Once it coughs it will run on one or two more pulls, but getting that first cough is a challenge. Spark plugs are clean and dry, fuel is fresh, runs at full throttle and idle with no problems once it gets going.

Excellent

Good video!!!!

[@davemilster]

You mentioned reinstalling the “main jet.”I believe you meant the “needle seat”. I’d really love to know WHERE the main jet (high speed jet) is located on these carbs.

How can i find the year on mine 9.5 hp evinrude?

Tag your n stern bracket with model number

Well done T-Mike! I previously rebuilt my 9.5hp carb and it was in great condition like this one but the 2 round silver rivet pins holding the brass hinge that the float arm attaches to are not pressed firmly into the carb body, making the hinge a bit loose (has some play up & down & to the side). Strange to have found both pins sticking out slightly and was probably made like that somehow by mistake from factory. Do you have any suggestion as how I can best fix it? Can those two rivet pins be punched in further so the brass hinge sits tight against the body?

[@michaeljsimon]

Sorry. No help here.

[@nickmav682]

@@michaeljsimon No worries thanks. Will need to work something out as I find that if I press the primer bulb a bit too firmly once it hardens, a little bit of fuel will come out of the breather hole of the carby indicating the needle is not fully closing but it is a brand new seat and needle. Once it starts and runs there is no fuel overflowing and it is fine. It only happens if the primer bulb is pressed with a bit of force. Never a problem on other outboards I have and I can only put it down to this.

[@michaeljsimon]

@@nickmav682 sounds like you got it figured out correctly.

Is it the ethanol in the US gas that requires most of the carburettor cleaning? I seldom clean my carbs, it is usually not a problem. Living in Europe I wondered if it's the difference in gas spec. Btw, thanks for all your great content T-Mike, you are a living outboard ensyclopedia.

[@evinrudej]

Yes it is the ethanol in US which is very unfortunate. Usually as long as I run the gas out of the carb, so the ethanol doesn’t build up in the carb when I’m not using the motor, it will usually run good for about 3-4 seasons before needing another carb cleaning. What outboards are you running in Europe?

[@evinrudej]

Also I have some of my outboards posted on my channel if you want to check it out!

[@aziggy1039]

@@evinrudej I live in Norway, a country with a fairly high living standard. So there are not many of the good old outboards left (OMCs, Mercury etc). People just buy new ones and don't care about the old. However, being an engineer, i enjoy the simplicity and quality of the vintage OMCs in particular. Due to the impact of the 2nd World War, mostly outbouards from the post 50's are ocassionally for sale (60's and onwards).

[@aziggy1039]

@@evinrudej I see you have a Johnson 4hp. I have an Evinrude 4hp from about the same period. They good little motors 🙂. I have posted a video of it if care to see

[@evinrudej]

@@aziggy1039 ah I see that is too bad I wish you guys had more over there because like you mentioned you can’t beat the simplicity and quality of some of these old outboards. The newer ones are fine but I wouldn’t trust the reliability of a new one over an older one any day. Thanks for checking out my channel I’ll take a look at your evinrude 4hp loves these little motors very lightweight and powerful atleast for a 4hp.

You forgot to install the spring clip onto the float needle and clip it over the float plate.

[@michaeljsimon]

That carb needle does not have a clip / only when I rebuild the carb and replace the needle do I use the clip.
