2013 T2000 Craftsman 42” rider with 19hp B&S 540.
2016 at 3 years, 3 months, compression relief system failed. $800 to rebuild damage. B&S refused warranty fix. My $.
2016- 2025, Until August ran normally.
2025 August. Started to be same locked compression, no crank, hit hard spot and no spin. Half dozen times. No question, spin until hit hard spot. Engine would eventually spin to start after recharging battery to max each time.
2025 October. Magically began starting normally every time. Started normally for 10-15-20 times mowing and leaves.
2025 November. Still starting normally, BUT the famous choke start, run perfectly, sputter, die cycle started yesterday. Restart and repeat began. 50 times.
2025, November, today. New fuel, new fuel filter, old complete carb removed and replaced with brand new complete carb, PITA but doable. With new carb, the Engine started instantly, ran, sputtered, died just like before replacing fuel, filter, AND carb. 20-30 times exactly the same. Choke start even hot, run smooth, run rough, sputter, die, no matter where throttle is (choke, run, medium, idle). It would generally restart in any throttle position. Quicker choked.
When it changes from smooth running purr to sputter, the governor arm starts fluttering.
Gas in tank, inline filter mostly full, full flow if carb line taken off. Gas is going into new carb just fine.
Is this the compression relief system again?
