Can you provide the specific Model-type-date code please?

Many years ago I was in the US Army and had a test. The question was “You’re driving down a road in your Jeep and it stops. What’s the first thing you check? C. Gas

Possibly fuel related. Did you add fuel before this began? Could it be a can of fuel with no top where water, dirt, or insects could contaminate the fuel?

Congratulations on your found by the side of the road self propelled push mower?

Auto Doc may be correct. Please post pictures or a video

I have a thought that inside the governor has failed. It can be replaced but it’s a bit of work with usual new gaskets. Are you willing to do it?

Order a replacement carburetor now please. You’ll thank me. That is a plastic carburetor that can be cleaned. However, for your time and money it’s easier to just replace it.

I think you have a bad pump or wand. I’ve seen this behavior before. You engage the wand and it starts to build pressure and then nothing. I hope I’m wrong

Great job getting it running again. Is it possible to clean the wire contacts? Do you know which switch might have been the problem?

Success!

Ebay is a good source for used and aftermarket parts. I’ve had success with Rotary brand for Briggs aftermarket parts. On eBay you can occasionally find good value on NOS Briggs parts.

What’s your plan now?

Sounds like a possible safety switch or key switch issue

Sounds like an automatic choke is staying closed.

Excellent!!! So now we work on spark at the correct time and fuel. Any changes in fuel? How is the flow? Fuel filter?

Let’s see compression numbers please? Might want to try a few ounces of seafoam in the fuel

Is it possible you have a failing coil? They can fail in under a year. Can you swap the coils to see if misfiring follows the coil? I’d love to see the compression numbers. I read you listed backfire? What causes a backfire? Exhaust valve not closing correctly? Fuel not burning from lack of...

New spark plug wires? Did you replace the coil and wires? What is your compression on each cylinder? I’ve had to remove the spark plug boot then clip a bit of wire off then reinstall the spark plug boot to the clean wire. Misfiring went away.

X2 for check your valve clearance. Possible failing starter or wire connection What happens if you hook up jumper cables to the battery from your vehicle? Does it spin over correctly then?

Looks like you have been given excellent advice above. A short term solution, just to get you through the HOT current cutting season, is to give it a shot of starter fluid. Then, once it is cooler, you can check the gasket, fuel flow, and primer bulb.

I’ve seen this before on a new fully charged battery. I’d characterize it as normal. My words would be “Send it”

It looks good! 14 volts is normal. Here is something I learned on Honda Express mopeds …..the battery is part of the “voltage regulation””. The 14 volts is expected to keep the battery at 12.X voltage.

Do you have it setup? It seemed to me the photo showed how the internals setup clearly and I’d hoped you had it working now?

You got it?

I have used a gasket remover spray and then clean the surface afterwards. That seems to work best. In the past, I used only a flat razor blade to remove the old gaskets while working very carefully not to remove any metal. I did my best.

Wonderful news!

I’m certain you will travel out of state and pickup a replacement one day. So disappointing to read this about The Great State of California.

Ticking bomb

The keyway angle may be different effecting timing.

Send it

Sounds like wisdom

Just to help you. I have shortened the long fuel pickup to and put fuel line from a weed eater and a weed eater fuel filter on then end to rest at the bottom of the tank. The diaphragm fuel pump on the side has no issues and the cup at the top stays clean. Just an idea for you

Here is a post from a few years ago about the baffle. https://www.mytractorforum.com/threads/molded-sponge-filled-gas-tank-news-to-me-pics.999577/?utm_source=google&utm_medium=organic5HP Fuel Tank Problem You might want to look for a Honda GC135, GC160 or a GC190 off a broken pressure...

It’s a plastic baffle to help with the sloshing. I’ve seen a sponge inside there too. Bad idea because it deteriorates and clogs up the carburetor. I would remove the tank, then I’d remove the baffle and clean the tank. A replacement tank is about $100 last time I saw one.

I understand what you meant and you are correct. It’s possible to get this engine running now. Personally, I’d find a good used flywheel that is correct for this engine that matches the correct keyway and call it a day. I’ve seen them available for as low as $60 and as high as $160...

There is a free app called “VMT” or Vehicle Maintenance Tracker. It’s great I too write on my equipment or use a label maker to document services

I didn’t see where you removed the flywheel to inspect the key? I think you are working on spark at the correct time?

No. I too have seen racing engines without a flywheel key and they used valve lapping paste to hold it to advance or ****** the timing.

There are three primary things you need: spark at the correct time, fuel, and compression. I use the Walmart starter fluid. I sometimes remove the spark plug, spray a shot in the hole, reinstall the spark plug, connect the spark plug wire and then try to start. 95 percent of the time the...

Photos would be helpful. Does it have a control plane? I believe I had this engine and it was fixed speed using a spring and a tab. You could bend the tab to get 2800-3200 rpms

I’m with the team to drain bowl and tank. Definitely possible to have a blockage, but after everything is drained a shot of starter fluid should get it to fire. Have you checked the flywheel key?

Definitely a possibility however It’s sold now. I’m certain the correct replacement will show up soon

I see his flywheel on eBay now. It matches via the Model and date code. It has 12 magnets on the inside. The keyway matches to the current broken flywheel. The seller did not put the Briggs part number in the description but there are lots of photos. Item number 158005448071 Mowermandrew is...

I believe your part is on eBay now for about $100 delivered. Briggs And Stratton Flywheel For 17.5hp 31C707 Your photo shows your date code as 120514 so it should be a match. A good used flywheel with good ring gear and tight magnets, use before code date 12071800 removed from a 2002...

What can happen is you send them the photo of your old flywheel and they can verify before selling you a replacement. I’d be willing to bet you can find a used flywheel off eBay and visually compare the keyway to the coil magnet on the outside to the listing before purchasing. You have been...

These are not the same flywheels. I see the keyway is 12 o’clock on both. The ignition coil magnet on the top one is at about 1 o’clock. The ignition coil magnet on the bottom one is at about 10 o’clock The magnet on the flywheel is where the spark originates and the keyway is critical to the...

Just at first glance. I do not see a keyway in the top flywheel but I definitely see a keyway in the new flywheel? I had one with the keyway off by 15 degrees and it was the wrong one. You set them upright with the trigger coil magnet down and they should be the same angle. This is the...

How do you know you have the “correct” replacement flywheel? It seems your trouble shooting skills are excellent and IF everything is correct it SHOULD run perfectly. I’m thinking the flywheel is incorrect. It could be the magnets are oriented differently North South instead of South North...

Let’s see if I understand this correctly. 1. It’ll only start on level grade 2. You moved it an it wouldn’t start with starter fluid? To me I suspect no spark or no compression. Big 3:Spark at the correct time, compression, and fuel. If you hit it with starter fluid it should have fired off...
