Hello all, I am new to this forum and I came for some advice. :howdy:

I have a JD L11 with a B & S 11.5 horse motor. I maintain it and I've never had any problems with it until now.

Went to mow the lawn, started up fine and I flipped up the lever to engage the blades and it slowed down the engine and then it stalled.

It has a spark. The fuel is pumping OK, fuel filter is new, gas cap is vented. I replaced the PTO and seat switch and I cannot keep it running.

When I turn over the motor and spray carb cleaner into the carb it will start up run for about 5 seconds then stall out. It's the only way I can get it started but it won't keep running.

Is this perhaps a carb issue? Should I rebuild it? Is there a coil on this beast? I am allergic to having my machine serviced by others. :help:

Welcome to MLF!

You're right on the money regarding it being a carb issue. Since it is getting spark like you say and it runs on the carb cleaner, all fingers point to a dirty carb. It sounds as if has some gunk in it that needs to be cleaned out.

This is the L 111 that you have correct? Showing 20 Hp. engine on that?

Wonder if that has a fuel cutoff solenoid on the carb?

Edit, looking on John Deere parts it looks like it does have the solenoid on the bottom of the carb. That would be the first thing to check.

Here's how to test the solenoid:

Or maybe you have a Deere 111 like this one instead?

No solenoid on this one. Back to maybe a dirty carb again.

Thank you and I stand corrected; it does, in fact, have the 20 horse motor except right now the horses are dead. :dunno:

I will be tearing the covers off today and will check the carb solenoid. Thank you.

Good morning.

I check the solenoid with a fresh 9 volt battery and got nuthin'. So, I ordered a new on ($56 ouch!) and checked the carb out in the process. The carb actually is pretty clean.

The part will be here next week.

Anyone tell me what the torque would be for the intake manifold nuts?

Thank you all.

You're right, it is a 20 horse motor and yes it does have a solenoid. I tested it and it doesn't work. So, I ordered one and cleaned the heck out of the carb with spray cleaner.

We'll see what happens when I get the new solenoid.

Thank you!
