1973 Johnson 50 HP; Removing Carburetors

[@gregvanblaricum4204]

I've been searching for a video like this for some time now!!!! I have an older Evinrude (mid/late 70's) that I absolutely can not get to idle properly. I'm thinking I may even have a link or a spring missing. I know the spring from the choke to the power head is stretched and possibly not working properly. Thank you so much for this and just the good images as well to compare. Any tips would be appreciated.

wow my 73 is missing some parts and has extra parts, mine does not have the cover over the carbs but it does have sticking out of the carbs an brass flat head adjustment also mine has a lean rich knob that is missing the wire rod? very odd for sure

[@jeremygrunow5333]

I really need to see the low speed linkage i got the same motor and mine is missing and im trying to find a replacement but i cant get a good idea of what all 4 pices look like i have the knob for rich and lean but im missing up to the linkage

[@scottmitchellrose1732]

brilliant! I have a 73 evinrude 65 hp - has 3 carbs. I'll try this and let you know. my biggest worry is getting all of the linkage back together right...

[@TannerMccracken-h8i]

Brandon, I hope you find this I’m struggling I took the screw off for the manual choke and being the screw is a black extra piece. I did not see how it is supposed to be connected do you happen to have a picture of that and what’s it’s supposed to look like?

[@zarock169]

Thank you for the tips. Really helpt me there.

I have same motor.50 hp jhonson...was at lake Perris .ca. Yesterday and it just shut off like if it ran out of gas. Came home and I do got spark and gas..what should I check next?replace spark plugs??

[@davidgridley3643]

Thank you for this video. I need to do this

[@ericstephens5271]

I have a 1974 50 hp evinrude same carbs as your working on your main fuel line goes to the top carb mine is backwards perhaps it got switched can you tell me if I need to change it back

[@charlesbarrett5923]

How did you remove the air plate cover from the carbs?

[@317ibirish]

First off great video, I have a 1974 50hp evinrude lark looks exactly like this one . My question is I think I'm missing something cause the shit cable end goes on and held on with a nylon nut but nothing for throttle cable end it just pops off the little nipple how do I keep it on? Any help would be much appreciated 🙏 part numbers or instructions, thanks in advance!!

[@BrandonsGarage]

It's actually supposed to have a clip on the end of the cable. If you watch my video on connecting shift / throttle cables on my 1958 Evinrude, you can see it there. I'll dig you up a part number in the morning.

[@317ibirish]

@@BrandonsGarage that would be greatly appreciated I figured it had to be missing something but can find to much on the net about 1974 50hp evinrude lark, then I stumbled upon your video 👊

[@317ibirish]

Any luck on that part number ? Thanks in advance

[@6Tonjack]

How many turns did you set your idle jets to?

[@adriamsoderstrom8616]

I like your videos keep up the good work. Just got one of theese engine but she's running with a bit high idle where is the adjustment on it?

[@joshthompson3940]

I’ve got a ‘74 50hp Johnson... I was able to get it started but it would only run for about four seconds before shutting off... thinking it’s something with the carb but any chance it could be something else?

[@lmt-adventures]

Mine does the same, come to find out I was missing the retainer piece on the idle screw found in front of the carb right above the intake hole. Hard to find the part in my experience so I custom made a piece to push against with the carb cover holding it in place while still allowing air in. So far so good. What was happening was without the retainer piece my idle screw would slowly turn all the way in tight when motor is running and vibrating, ps: my motor only starts and idles well at 2 full turns out from the tight position of the idle screw.

[@collinthomas8823]

Im getting gas to the carb but when I pulled the plugs they was bone dry and I don't think I'm getting spark

[@BrandonsGarage]

floats stuck? reed valves rusted?

[@collinthomas8823]

@@BrandonsGarage I'm not sure the guy I work with is supposed to come look at it for me im just a roofer never been much of a wrench turner

[@AB7F9]

thanks for vid. got 60hp with tripple carb. thinking of cleaning up. did you remove jets etc or simply just soak or spray carb cleaner at them? Can the floats just be reused after cleaning. Is there a point the floats need to be replaced? Thanks

[@mikekmalick]

It doesn't look like you are going to get an answer from this guy. It looks like he used his old gaskets and floats. My recommendation is to get a carb kit and with the kit you should get new gaskets, needle valve, float and pin. The jets can be cleaned and reused for they are just a brass orifice. Im sure you got an answer by now but couldn't help myself.

[@scottcoleman284]

Those are a little different than my 73 50 Evinrude, mine have low-speed adjustment screws coming out the front of them.

[@BrandonsGarage]

manual start motor? also, I think they sold and adjustable add-on kit for this

[@scottcoleman284]

@@BrandonsGarage it's an electric start and electric choke, but you may be right about it being an add-on because it also has a manual choke on the cowl which connects to the carbs and functions but also has an idle adjustment knob in the cowl that is just a knob, it doesn't go to anything.

[@scottcoleman284]

@@BrandonsGarage It just dawned on me that the adjustment knob I was referring to may possibly be a knob that pulls out of the cowl to use on the low-speed airscrews. The screws have knurling on them for a knob, but also have a slot for a flathead screwdriver. Also, the airbox has two removable black plugs to access the screws.

In those cans you said you had soapy water
