  • 24HP Briggs hunting
  • I bought a new zero turn mower with a Briggs 24 HP motor on it late last fall. It only has about 20 hours on it now. It ran perfect when I started it up this spring. After mowing my 3 acres, I turned off the PTO and the engine loped or was hunting. It runs perfect with the PTO engaged. Dealer said it was fuel related and not covered under warranty. Is there any "snake oil" treatment that can be added to the fuel to clean the carburator as it is being run? I would hate to pull the carb for a cleaning job if there is something that would clean it as it is being run. It is usable as it is now, but it does not idle smoothly.

  • I have a V twin briggs in one of my lawn tractors. Come to think about it, it used to hunt when it was new. I cleaned the linkages real good, and I would give it just a tiny bit of choke to settle it down. It seems like once the air filter got dirty it ran better so I only clean it when it starts running rough. I like the V twin it runs much smoother then a single thumper...

  • So we can use it for lantern fuel too. That is good to know.

  • Look for dirt clogging the idle circuit.Seafoam costs 80 bucks a gallon.You can buy naphtha at walmart for 7 bucks a gallon.Seafoam is naphtha with a 10X price tag.

  • Try a can of seafoam. If you can shut off fuel, run carb dry when storing for months. If no shutoff run it out of gas or use seafoam in gas. Add seafoam now and it will dissolve some sludge.

  • I purchased a can of Sea Foam and will give it a try. The dealer also sold me a bottle of gas treatment sold under the Briggs name ($13.00) Doing a web search on Briggs surging problem, I came across a site from Briggs that said this is normal until the engine is broken in. This is due to the newer tighter emission regulations which mandates much tighter tolerances. Will give it some time to see if it goes away. Thanks for the suggestions of trying the Sea Foam.

  • I have found idle passages in JD carbs full of a fuzzy material.It had to be cleaned out with gas welding tip cleaners.

  • Anotherthing that can cause surging or hunting is a rusty or dirty linkage to the governor. Make sure the linkage is free of debris and oiled with light oil. Oil just the pivot points so dirtdoes not collect onli kage.
