So, why won't your riding mower turn over? I'll show you how to first diagnose this common Briggs & Stratton Intek camshaft decompression (also called compression release) issue, how to determine it's not a battery or starter issue, explain how the decompression cam works and the easy steps to repair it.

When this decompression / compression release part breaks (which research & experience indicates many will), the symptom is pretty much identical to a weak battery or bad starter the engine tries, but won't turn over.

What happens now is many people will replace the battery first, then the starter and perhaps even the starter solenoid; only to find out $200+ dollars later, their riding mower Intek engine still refuses to turn over. Welcome to the popular & growing club of Briggs Intek owners who have had a decompression camshaft failure.

The repair is not that costly or difficult for the mechanically minded DIY'er; but it's a time consuming repair and is why most shops charge several hundred dollars. Some (like our local shop) will even say it's not worth fixing I disagree.
