Kohler Courage 20 / SV600 Walbro 3 carburetor leaking from float valve

[shrout1]

stuffed
A polite way to say bend over & spread em , totally beyond use , etc

Now I just feel like an idiot for not realizing that But that makes sense looking at the needle a little more closely

The inlet needle does appears to be ringed along being dirty.

The OP needs to replace the needle and seat on the carburetor. A known problem area with these Walbro carbs. Now the question is it gravity or pump fed? IPL appears to indicate gravity fed but just need to be sure as there are two different kits for these carbs.

Note: Most online IPLs will not list these needle/seat kits but they are available.

This makes sense! The carb is gravity fed from a tank that sits just a little higher than the engine behind the steering wheel. I have seen some videos of people using bolts to extract the seat - I haven't seen an example for this particular carb but I think the process makes sense....

Do you happen to know a part number or where I could pick up a new seat / needle combo? I will try to clean it first but replacement might be the better option.

if you look close at the rubber tip, it appears scuffed, any imperfections can cause it to leak. Bert is from Down Under so either stuffed is the term down there or it was a mis-type. He may not have had his coffee yet.

Also, that is awesome that there is a member here from the other side of the planet I'll be learning my Aussie slang in no time. Communities like these are amazing; I've kept beaters on the road and fixed things I had no right fixing thanks to boards like this. Excited to pepper you guys with all my stupidest questions

I especially like figure 4 - it's like, "Yank it really hard with pliers"

You actually use the installed bowl screw and lever the seat with the large pliers [longer the handles the better]. That is why they provide you the bowl screw.

I know not the best instructions provided but that is how it is done.

Hey thanks a million for linking that Can't tell you how helpful that is - I spent hours trying to find part numbers and figure this out before coming here.

This carb has a fuel shutoff solenoid that holds the bowl to the carb body - is that typically done with the screw? The design is actually quite obnoxious as you can only attach the bowl and solenoid once the carb body is on the mounting studs. The solenoid sticks down far enough that it interferes with the frame of the mower when you try to take the carb on/off. So... I get to put the bowl and solenoid on in place every time.

Edit: And regarding pliers - I have some 10" linesman pliers that I use for electrical around the house so... that should get the job done

I have done it like that a few times myself. Also I have used the two mounting nuts, jam them together on the left stud and then unscrew the left stud to be able to rotate the carb. the right stud is square headed to the back of the plastic carb mounting isolator. And is held on by the screw that connects the ground wire for the solenoid Don't like that one as much due to possibly tearing the gasket behind it when you rotate the isolator

Yep, i don't care for that mounting design very much, guess it cost too much to drill and tap an extra hole for a stud

I was extremely surprised to discover it was done this way. Rotating the carb does make sense, but it probably isn't worth the risk. Oh, also my grounding wire totally broke at the screw in the carb so I need to get a new end for it

Any good suggestions for that? It's a silly little part but I really don't want to set the mower on fire either
