What causes a riding mower engine to run rough?
The carburetor mixes fuel with air to create a combustible mixture that enters the engine cylinder and ignites to drive the piston. Impurities in gasoline can clog the carburetor, preventing the engine from starting. Carburetor clogs can also cause the engine to run rough and the engine may stall when you try to drive the riding mower.
What should I do if my car runs rough?
If the engine runs rough or misfires, it could have a clogged carburetor. Rebuild or replace the carburetor if it’s clogged.

Cranking speed too slow to start. Spark plug loose. Low or no compression. Spark plug gap incorrect. Engine not properly warmed up. Running out of fuel. Low idle set too low (Below 1000 RPM). Low idle fuel setting too lean. Electric clutch dragging. Parasitic load on PTO shafts. Crankshaft end play zeroed drive. Water contaminated fuel.
Why does my car run rough with no gas?
What I observed was that an engine can have quite a few things not functioning properly and still run- The fuel pressure regulator can be inoperative or the EGR can be non functional and you may not notice it, the exhaust gas sensor may not work , so the engine runs a bit rougher etc.

When does a solenoid need to be replaced?
Starter – Some solenoids are mounted to the starter, but some are located directly inside the starter housing. When this is the case, it may be necessary to replace the entire starter when the solenoid goes bad. Sometimes the starter itself is the problem. Electrical issues can be annoying and inconvenient.
Why does my solenoid make a clicking sound?
This could mean that the solenoid is trying to engage but that the internal components are stuck and unable to work properly. 3. Repeated “clicking” sounds usually indicate a dead battery.

Why does my Briggs and Stratton engine run rough?
Another thing that effects a warm engine running rough is a coil going bad. You need to look for something temperature related. Cleaning carburetor, spark plug, gas, flywheel key and mag spacing wouldn’t have anything to do with the engine temperature. Three different spark plugs with same result. Could the magneto be bad?
Why do I have a rough idle with a twist?
On the plus side, the engine revs a lot faster in neutral with the new timing chain set. Since the cam position sensor (and adjusting the distributor) are what sets the fuel sync timing, I can only hope that installing the new timing set is what threw off my fuel sync timing, causing the poor gas mileage and hopefully the rough idle.
What to do if your riding mower is running rough?
Check for fuel, oil or carbon deposits on the spark plug. Replace the spark plug if it’s fouled. Bad fuel causes a rough-running engine. Drain the fuel tank and fill it with fresh gasoline if the fuel is over 6 months old. Use fuel stabilizer to keep the gasoline fresh.
