Help: Sears 10xl walbro carb adjustment
Posted July 16, 2015 - 08:05 PM
I adjusted the carb how walbro said to. Got it to fire up but it seemed to be flooding. So I turned to bottom screw and it started to shut off. I turned it back up some and then turned the screw on the side but couldn't tell nothing.
Anyways, I raided the throttle and it ran good but thinking it was still flooding. I lowered the throttle all the way down and it then turned off.
I can't get it to fire up now.
The carburetor also looked to be having gas coming out of it from the top. I have a picture of it below too.
I took the spark plug out and it was black and wet..so it was flooding
I will upload a video as well.
What am I doing wrong?!?

My experience with Walbro carbs ---> either they work or they don't.
I fought a Walbro on my JD 120 for over a year and ended up swapping on a different carb.
Definitely change the oil before you run it as gas will thin it out and do bad things.
Here are the basic steps I would take if it were my machine:
- soak carb in carb dip
- blow out all passages with compressed air
- rebuild with new needle, gaskets, and float following Walbro specs
Let us know how this goes.

I'm betting that float is not set right or a little heavy causing it to flood. If that spring pushes float down, maybe remove it and see how it works. I also start out at 1 1/2 turns on both screws and work from there. If I remember the side screw is for low idle mixture, the main on the bottom is for the rest of the rpm range.

Here's what the carb book says
When I got the carb the dampening spring wasn't there.

Flip the spring which way?
Throttle has little side to side play but not a lot.

I thought it said to have the small bend under the gasket?

Did you blow the carb out with an air compressor?
If you did you more than likely blew the rubber valve seat out.It will never seal without that little bugger.I've done that a few times.Usually if you blow it out you'll never find it unless your really lucky
