Just an update. In my months long journey to repair the mower it turned out to be a broken push rod on the exhaust side. Actually, it was broken. I suspect it bent the first day the mower shut down but after all my attempts to start the engine, the rod finally broke. The OEM rod is made of...

I've been trying, unsuccessfully, to diagnose the no-start issue with my mower; Murray 425009x8A with B&S 31R907-0007-G1 engine. It died while I was mowing. The flywheel spins and I can get it to run at 1/4 power for a second or two. I've been assuming that a bad switch would be like...

Thanks for posting the diagram. My seat switch has 3 yellow wires. Two are connected as shown in the diagram. I’m not sure where the third one goes. Also, I disconnected the “main” yellow wire near the solenoid to bypass the shit off switches, but still couldn’t get it to fire.

I found the fuse. Removed all the grass from the connection and replaced with another one but wasn’t even turning over. So old fuse replaced and taped up good. Motor turns, so fuse isn’t the issue.

The purpose of placing the mower and engine model numbers in my signature was to make it easier for everyone to see and it would show up on ever post, not just the first one.

Yes. New gaskets installed on jet, top of plastic carb inner and main seal for bowl. Jet is clear as is throat tube. Used lots of gumout. Installed new plug this afternoon even though I saw spark with old plug. Found an unplugged wire under seat shutoff but nowhere to attach. Posted about it...

Model number in my signature

Found this loose wire under the seat of a Murray 425009x8A riding mower. I'm hoping it's the reason I can't get the B&S motor started. Don't see any other loose ends, and can't understand the wiring diagram. Thanks. Untitled by Larry Johnson, on Flickr

Been trying to get a B&S started. Found this loose yellow wire under the seat but don't see another end to plug it in. I can't figure out anything from looking at the wiring diagram. Also, where's the fuse hidden on a murray Untitled by Larry Johnson, on Flickr

The saga continues. New carb gaskets installed, now carb is no longer leaking. Still can't get engine to start. It ran briefly with choke engaged but was only a "half-assed" attempt and shut off immediately when throttle put in run position. I don't know what to check next. To recap: carb...

OK, found a video that showing how the auto choke linkage floats in the slot. Gapped the plugged. It was way tight. Checked spark and magneto. Getting good spark. Backfired when tried to start, then started at half power for a couple rotations, but won't stay running. Gas running out of...

The solenoid was a little sticky, so gunked it clean. It responds well now. Uhhh, how does the "slide trombone" linkage connect to the flat plate with the hole. Did I lose a spring.

Trying to figure out why the mower won't start. It's getting spark. Looking into carb and noticed the unfilled hole on and the small black piece I'm pointing to. Is something missing or broken. I've got a parts manual but no real good drawing showing linkages. B&S 31R907 0007 G1 code...

Bought a used Murray with a B&S motor, 31R907 0007 G1 140924ZD about 2 months ago for use at my home. It started every week with no issues until yesterday when it cut off after about 5 minutes of mowing. The gas is good and flowing to the carburetor. I did see a spark at the plug once, but...

It's alive. All I did was squirt some wd40 in the connection and let it sit overnight. It must have gotten wet with al the rain.
