How to fix bent pushrods in a riding lawn mower: Briggs and Stratton twin 24hp engine

[@franselinger9150]

I kinda missed the background music with this video, but from all the great comments, I think I'm the only one! And if that's the only complaint... Well done.

Very good video! Thank you Sir!

A master mechanic at work!

Awesome repair like that hack you did to keep that valve guide in there👍🏾

[@jasonselinger]

It’s still working great! Not a terribly difficult fix, just took some patience.

​@@jasonselingerAwesome we just did something similar on FR651v Kawasaki bent push Rob on #1 cylinder and stuck guide had been running and cutting on one cylinder now she's firing 💯💪🏾

Got to love that factory design flaw on those Intek motor head gaskets all that blue smoke keeps the mosquitoes away when you're mowing not to mention filling up your neighbors yard with smoke

It’s all ways a nest of trash grass that causes this when engine overheating and guides move out, driving it back is only temporary fix New head or drill for set screws 😊

[@mikewright2917]

I had a Briggs that would do. This. Turns out it had a valve guide that would slide out of position.

[@jasonselinger]

That seems to be a common problem. Easily fixed though.

What's Loctite going to do heat losses the chemical? Great fix!

The reason the valves bend is due to bad fuel and a stuck valve/rocker arm. The impurities in the fuel creates a deposit on the exhaust valve when burned, which, over time, pushes the valve guide out of the head. This prevents the valve from operating properly and also causes the rocker arm to hit the guide, bending the valve. I repaired my B&S engine twice, before discovering that. I started using a fuel conditioner, like Lucas, and have not had an issue in since! It's been years since I've been using the fuel conditioner and I use it on all my gas engines with zero issues.

[@jasonselinger]

Great advice! I’ve been using Seafoam for quite a while, but this damage happened before I had the mower.

[@JimTaylor-ui6yr]

Sorry, it's not the valve that bends, but the pushrod...

[@jamesm568]

I have a 24 horsepower Briggs & Stratton intek and the only time it bends the push rods is when the damn bolts come loose that holds the rockers.

Nice video. Is it safe to powerwash it like that?

[@ScottMiller-tu3gg]

Thanks a million! Mine did the same thing - same mouse nest, same cylinder.! My pushrod bent and I was able to pull it out also. Does this cause any internal damage to the engine (other than the pushrod and valve guide)? It seems like my engine turns over a little hard by hand by turning it over with the plastic guard on top of the flywheel (with the spark plugs out). I am thinking it is harder to turn over since I am moving 2 pistons and other parts. Also, when you drove the pushrod guide back in, is it flush inside of the head? Thanks in advance for any advice!

[@danielhowell4211]

Yup my mower broke down yesterday and took engine apart. same mouse issue you all had. Did you get your mower fixed? At 6.27 in the video he has it almost flush from the top.

[@ScottMiller-tu3gg]

@@danielhowell4211 Found out my engine has a broken connecting rod - the engine is trash at this point!

[@Seavoyager45]

Vice video, what is the correct height to set the valve guide, when to stop pounding it back in, is that about an 1/8th of an inch from flush?

[@jasonselinger]

I set it at the same height as the other guide. I think it was closer to a quarter of an inch.

Inspect engine with the cover removed at beginning of season 😊
