Thanks for the reply. I sprayed 2 cans of carb cleaner through it trying to get the mower running on gas. Then I removed it, drained the bowl, wiped out a small bit of sediment and replaced. Is that not sufficient?

Did you get the mower running. My mower suddenly won't run on anything but carb cleaner. Was carb float the issue?

Can't figure out why mower won't run on gas, but will run on steady stream of carb cleaner. I've been using the old mower for 5 years with no issues. After a number of uses this year, it just stalled out. I assumed the gas was bad, so I emptied the tank, lines, and carb bowl. The only way it...

Well, the starter gear needs replacing. IMG_2685 by Larry Johnson, on Flickr

I believe I added some bad gas to the tank and mower died 2 minutes after staring. Can't get it re-started. I drained a bunch of gas from the tank and all of the lines, changed the fuel filter, which was nasty, but still won't start. I can get it to start briefly with a shot of carb cleaner...

Trying to decide which mower to keep. I've got an old 46" Murray Lawn tractor with B&S 406677, type 0344C1 2-cyl OHV engine that I've been using for a few years. I resurrected it from the dead. It's set up for mulch cutting, so it makes a mess of me and it. Seems like I'm replacing a belt...

Excess oil buring suggests bad head gasket, no? When I replace the sump gasket and head gaskets what else should be done while engine is dismantled. I'll clean or replace carb float needle and add gas shut off too.

Head gasket replacement looks easy enough. After wiping off the oil and running it this morning, I noticed an oil leak shown below. What's this gasket (behind starter)? Difficult replacement?

Didn't realize someone replied. Thanks, Walt. The seller thought it might be the rings. Not sure why he suspected so. The oil looks "weird" to me. Maybe a hint of gas. Can gas get into the oil any other way beside head gasket. Here's what the plug looked like Does that suggest bad head...

I picked up a craftsman mower with a smoking 331800 (3318771371, code 100913ZD) B&S engine from my neighbor. Knew it was smoking, mainly just when throttling up hills. Wondering how reliable this B&S engine is. Head gasket blown?

After backing the mower out of the shed, stupid brake pedal got stuck in the down position. Won't budge and won't go down any further. I removed the rear wheel, brakes and springs. No movement. Before the sun set, I tapped the pedal with a BFH. No movement. I'm stumped. What's going on.

Me mower stopped like a mule in it's tracks halfway through cutting the front lawn. Figured it was the (rear) primary drive belt, but it's in tact. The longer, secondary belt (49) is broke. From the diagram it looks like this belt doesn't have anything to do with making the mower move forward...

Working on cleaning the carb of my pressure washer per all the videos I've watched. Is the little ball thing pictured here suppose to move in and out? Untitled by Larry Johnson, on Flickr Also, wasn't able to get the inside needle valve thing removed despite countless banging on the bench...

Just a couple years old, little used pressure washer won't run with choke in. Runs at half power with choke pulled. Ethanol issue? Clogged jet? I always turn off gas and let it burn through remaining before storing. I don't really know much about them, but if I know what to investigate, I'll...

What causes the right rear wheel to be coated with mulched grass while the left one stays clean. I know the grass has to go somewhere with a mulch blades and cover installed, but it seems like it's still forced towards the right side exit. Cleaning out under the deck today I noticed that there...

Occasionally, me mower won't shut off with the key. When it does this, it comes close, but won't completely turn off with the key. I just turn the key back on, then off, and it shuts down. The kill wire on the coil is attached and isn't rusted. The main wiring harness and starter solenoid...

How is this new pulley suppose to be secured to the new spindle when the threads stop short? There's a spacer on the new spindle. It came already attached. The pulley lines up with the wear marks of the old pulley. It doesn't fit upside down either. Thanks. Untitled by Larry Johnson, on Flickr

Had to get a new spindle and screws for a 46" deck. Bought aftermarket spindle and B&S bolts from Jack's Small Engines. The bolts/screws are standard flat end threaded, but are called HD Tap. Will these tap their own threads into the new spindle whose hole is too small for the bolt to go all...

What's the secret to removing the top gear for replacement? There's no pin to pop out. Replace with aluminum or plastic? found a video. https://www.youtube.com/watch?v=D1SeNsYxGYs

The B&S V-twin that I brought back to life last year and used all summer is acting up. I sounds like someone is killing a cat when the key is turned. I used it once this year and started it sunday, but I had to turn the engine by hand a couple of time in order to get the starter to spin it...

I'm enjoying my new used mower, but having issues with the bagging chute. The result is clumps of grass sticking to the right rear wheel and ending up in a trail on the driveway. Nice green stains. I only bag when I cut the front yard. I only cut when the grass is dry. I mow regularly...

I couldn't see paying $35 for a plastic mulch cover plate. Couldn't find a used one. Thought about making one from wood, but don't have a steam box to bend the wood. Sheet metal crossed my mind, but I've never had the skills to cut it properly and I only have hand shears. Had a bright idea...

Picked up a 2005 Murray Lawn Tractor off of craigslist for free a few weeks ago. With the help of some kind folks here, managed to get it running and in good working order. It came with a bagger attachment too. It's not bad looking at all. The front grill was missing, so I just pop riveted...

Could a missing variator idler spring cause the drive to take a few moments to kick in when the "transmission" is engaged. I'm troubleshooting mine and noticed that I don't have such a spring. It's shown at the bottom of the following diagram. Here's what my variator and belts look like...

The resurrected B&S v-twin ran fine for about 15 minutes cutting grass and then just stalled out. The new fuel filter was dry when it shut down. Had about 1/3 tank of fuel. Thought either had a fuel pump issue or vacuum issue. Blew out some crusties from the fuel cap and allowed engine to...

Almost ready to put the Murray into action, but having an issue with the center spindle on the cutting deck. The spindle/pull turns by hand without blade attached, but will not when blade is installed. The outer two spindles are fine with the new blades installed. I was able to get grease...

My B&S v-twin will only fire when the "kill wires" are unplugged from the coils. I understand that this means I've got bad kill wires. What part needs to be replaced. Just back to where the wires are enclosed in plastic, as shown below, or does it go further back. Thanks. Is it the diode...

Trying to dignose an OHV v-twin. Bench tested the coils with an old analog ohmmeter, but not certain how much resistance indicates a good coil.

Received the key to my freebie Murray mower (model 465306X8B with B&S V-twin 406677 type 0344E1) today and gave it a try. Of course it didn't crank. Help me diagnose the problem. I'm not much of a mechanic and resort to the internet for education. Background: mower had been sitting a few...

I inherited a non-running Murray Select lawn tractor (model 465306x8B). It's not in bad shape. Hasn't run in a few years and the word is it may need a starter. 2006 battery is at 5 volts. Just ordered a key for it and took some of it apart to clean. Drained the old fuel and pulled the...
