This 21 HP Briggs & Stratton has too much compression! Let's change the cam / compression release.

No thank you

[@billsimpson604]

Free is usually good.

[@genewalker7499]

Way back did wave top dead center need done or not

[@GlennsSpeedShop]

I don't understand your question...

[@philliphall5198]

At the price of new mowers I’m fixing as many old mower engines I can and building very good engine with lots of new parts Will sale or need them some day

[@GlennsSpeedShop]

I have a 16.5 HP Kohler Command on the shelf, not for sale, just in case I need it ..lol Glenn

[@donnaraggio]

Compression release is on intake valve, engine upside down on work surface.

[@GlennsSpeedShop]

Exhaust valve.

Intake valve ​@@GlennsSpeedShop

[@Khromaaaa]

You're super underrated dude! You go so deeply into detail when you were explaining how you were fixing the compression in that engine good job!

[@GlennsSpeedShop]

Thanks for the compliment. Next video, we see if it runs...

[@lundyracing]

I’m thinking I’ll just use the stock cam with the compression relief mechanism removed completely and just use a manual decompression valve for a chainsaw.

[@GlennsSpeedShop]

I have thought about that too.

[@philliphall5198]

Yep a B/S engine

[@GlennsSpeedShop]

I put this engine for sale, have someone interested today. Cheers Glenn

[@philliphall5198]

Most of the time the block is damaged on the single cylinder I’ve even used HF rod to fix 6 of them and no leaks, so I have 6 back up riding mowers

[@GlennsSpeedShop]

I sold this engine the other day to a guy that mows weekly and it takes him 6.5 hours to mow! The man wears out some engines. I have 2 more on the shelf just like it to get to one day. Glenn

[@lundyracing]

HF rod?

[@teech16]

Are these cheap parts from Amazon (and AliExpress) alright and last a reasonable time without premature wear or failure? The genuine Briggs and Stratton parts are a lot more expensive.

[@GlennsSpeedShop]

Maybe I don't have an opinion yet, here is what I know. I have another video where I changed the cam on a Husqvarna Mower, it broke 5 min after warranty. I went to our local repair shop for a part, we ordered the cam on Amazon. I asked the mechanic there how common this was, and he pointed to 6 tractors all waiting on Briggs Cams that were hard to get, all warranty repairs. I have asked others your same question and their response was. The Briggs Cams are made in China, the Amazon Cams are made in China, how different do you think they are....

[@Dodgefan44]

Do you have a link to the cam you bought??

[@GlennsSpeedShop]

Mo, Amazon and Ebay has many options. Put in your engine model number and camshaft in the search.
