Thank you so much for doing this. I couldn't get my motor to run right, until I watched your video and realized I was putting the float needle clip on wrong.

Very complete and clear instructions. You forgot to mention there is also a metering orifice plug in the bottom bowl that could need replacement. The acertne bath is indeed very very effective. Finally, Sierra parts are acceptable but oem BRP parts definately are better. Cheap chinese parts offered on Amazon are to be avoided.

For the Welch plugs, use a small sheet metal screw. Tap and turn it a few times into the plug. Make sure the screw goes in a little crooked towards the choke side of the carb, so you don't damage the little holes in there. Keep turning the screw, and it will lift out the plug when it hits bottom. 😉

Slow speed needle is out 1 1/2 turns from a gentle seat, that’s on my 1988 25 HP Evinrude.

Thanks very helpfull.Mike from Michigan

Yes the high end gasket inside the carb is a must with out it, the motor will bog and doe when accelerating.

[alexandergrimme]

What is the brass nozzle he said don't remove? Mine needs to be replaced, and I can not find the part number

[artieyates]

My 73 Johnson has a jet in the bowl behind the bowl drain plug. Also 25hp. The Evrudes are different, without the long low speed needle

[iroc]

Do you have to remove the metallic plugs or can you leave them in.

[lmt-adventures]

I have the big metal plug at the very top and then the one inside the bow area, but missing one on side of carb instead I have two metal screen filter there, but a that normal?

[TacticalKhakis]

Couple questions….What side of the float bracket do you bend to adjust to level? Next, do the Welch plugs absolutely need to be changed and what’s the consequence of not changing them? Thanks in advance!!

[highlifegoodlife]

Is that lil clip nessasery on the float I opened mine and it dont have that

[soonerbred]

Mine has 2 carbs on a 40 horse is it two 20 horses or two 40 horses?

[MIKEYfishing]

How do you just adjust the float on a freshly rebuilt carburetor for a 77 Johnson 25

[billfraser]

i have a 25 hp 1982 johnson..the fuel hose from fuel pump to carb leaks at elbow no matter what i do. dont think is proper fuel line. what size would you recommend? can i get rid of elbow and go straight from fuel pump to carb?

[kone]

What about the white plastic "bearing" that goes over the adjustment needle tip I didnt see you put yours in on the video and I cant seem to get mine to go in the hole

[johnwilson]

The center tube that you took out by mistake miy 35hp has another tube inside it. My question is the tube is not perfectly straight. Is that normal? Motor still falls on it's face when under load. Put new fuel pump 1 coil and cleaned carb but did not take those 3 plugs out.do I really need to?

[ambrosehowell]

Good day, awesome video. So I need a new needle valve I have a 25hp model # F25RESB. So I’m looking for the part #. Thank you

[danbessent]

How many turns back from bottom on the low speed needle?

[JacksonBaumgartOutdoors]

Thanks for you help. Any idea about where to get an air filter that goes over the carborator where air intake is? My 1992 evinrude 25 horse didn't have one but based on the bolt holes I'm thinking there is supposed to be one there.
