Could be a few reasons for this..
First try a new spark plug, new gas filter, clean the air filter and check the gas line for cracks or leaks..
If the issue still exists - try spraying some carb cleaner into the intake while it is running in short controlled bursts..
Or the carb might need to be rebuilt.. If it sat for a long time - the gas in the carb will shellac and cause it to not work properly.. Or it could be a bad float in the carb..

Good luck..

When I engage the the cutting blades, the engine stops. What is causing this?


Check the mower and be sure you have not lost a bearing or else it is not binding. check to be sure the mower deck brake is not hung up. Something is wrong in the mower deck if everything is ok until you start the mower deck. Hope this helps.

17.5 briggs motor back fired 1 time and now when i engage blades the motor boggs down


The engine is timed internally and externally. Sometimes when it backfires the external timing key where the flywheel and crankshaft join will be damaged enought to put the engine out of time. The engine may run but when put under a load such as cutting grass it will fail. This is about a 30 minute repair and about $2.00 in parts.

My countax C300H starts OK but when I engage the cutters it immediately cuts out. If I let the engine run for 10 minutes then engage the cutters they usually work ok but this is pretty annoying. Is there...


Just got one of these mowers myself - accidentally got a large stone caught in the blades which caused the same problem. It looked to me that there's a sensor on the flywheel that cuts the motor if the blades aren't rotating freely. You might find either that the sensor is broken (check it by pulling off the connectors and connecting them together) or that the blades aren't rotating for some reason.

Safety switch at seat or reverse. Mower will cut of when blades are engaged if you get off the seat or put into reverse. Check these switches for stuck on, damaged, disconnected, or just plain broke. Good luck.
