Honda Lawn Mower - Runs for 2 minutes then stops

Model HRR2169VKA

It starts right up, runs for about 2-3 minutes, then sputters and dies. I've cleaned the carb, jets, replaced the fuel filter that was completely destroyed (shredded). Also replaced the spark plug. Any other suggestions? Was thinking of buying a replacement carb for $30 online, just not sure what else to try?

Thanks.

First thing I would make sure is that there is sufficient volume of fuel flow into the carb bowl. Maybe one of the lines itself is crudded up or perhaps the bottom of the fuel tank where the outlet is for the fuel hose.

Thanks, I'll check those things out. Strange thing is if I wait about 5-10 minutes after it dies, it will start right back up again. But it won't immediately start back up after it dies.

I agree, fuel flow is the likely culprit. If the fuel filter was shredded, pieces of it may have accumulated in the inlet of the carb. Sometimes you have to take the needle out and blow through it backwards to clear the obstruction.

Latest is I removed the tank, made sure it was clean and clear, also made sure both fuel hoses were clear and clean. Same thing happened after it was put back together. I just bought a replacement carb online for $26 so I'll try that next. Thought of maybe taking the fuel petcock out of the equation by bypassing it and running fuel directly into the carb. I guess it's worth a shot? Thanks.

I don't see that anyone else has mentioned it; but how's the vent in your Gas Cap.

Sometimes, a clogged vent will allow the engine to start and run for as long as it takes to create a vacuum inside the tank which then inhibits the flow of fuel and starves the engine.

The amount of time varies all over the place depending tank size, how completely the vent is clogged, engine size, et cetera,

Loosen up the cap and see if that lengthens the time span . . . . or allows it to run without interruption.

I never even considered that, thank you. I'll try it this evening and report back.

That is a good possibility, there should be a rubber grommet in there that acts as a valve, has an inlet hole and outlet. It could be bad or have something stuck in it letting enough fuel by to fill the bowl over time, but not to keep the bowl full while running.

It has been my experience that on Honda engines that behave like this one, you have to disassemble the carb INCLUDING the EMULSION TUBE and clean it out. There are tiny holes in the emulsion tube that get clogged and cause this.

Bypassing the fuel petcock didn't work and neither did releasing the fuel cap. Good point on the emulsion tube, but I removed and cleaned that with the rest of the carb unfortunately.

The new carb should be here tomorrow, so I'll ve very interested in seeing if that's the issue.

Appreciate all the suggestions, and I'll report back once the new carb is on.

Did you ever figure out the source of your issues? I知 having the same troubles by the sound of it. Mower will start and run for 2-3 minutes, then die. Can usually restart shortly after and will run 1-2 minutes and die. Tried cleaning the carb, no joy. Tried a new carb, gaskets, and a new auto choke assembly, no joy. Tried a new spark plug, air filter, oil change, no joy. Cleared fuel lines, checked gas cap vent, nothing is changing it. Wondering if you ever figured this issue out before I drag my mower to the dreaded shop to run up a bill.

Pull the fuel line off and run it into a container to see if it will drain the tank if it does it is not the tank or line. While it is running for a while spray/dribble brake parts cleaner behind the carb and along the mating surfaces to check for an air leak when the engine warms up. Install a new spark plug, Honda is finicky about spark plugs. Have a good one. Geo

Hey there, I ended up replacing the carburetor. Found one for $26 on Amazon. Runs great now. If you have the same mower, I can send you the link. It's actually $23 today with free shipping.

Yeah I already tried a new carb. Official Honda carb, not even a knock off. I dropped it off at the shop Friday, waiting to get a call and see what they think. It痴 possible I just happened to get a bad carb from the factory, but I知 dubious. I also tried 2 different spark plugs, and checked all the fuel lines twice. Only thing I didn稚 check was for vacuum leaks, but by that point I was tired of messing with it and just needed it out of my sight for a little while. My shop will diagnose free as long as you buy parts through their parts department, so I値l see what the pros think and then take it from there. Thanks for the reply.

Good luck, hope they get it figured out. Very curious to find out what they discover.
