| X320 Boggs down after 30 minutes of mowing. When I disengage the blades the engine runs fine but when the blades are engaged the motor boggs down and the blades slow to about a stop and then will speed up for a while. The mower has 120 hours on it and the belts seem to be in good shape and the tension is good. |

| Air filter good? |
|
| Air filter is good, spark plugs are good. It just seems to slow down and will sort of pulse but when the blades are disengaged it runs fine with no missing. |

| Check the vent in the gas cap and make sure the fuel filter is flowing OK. Have you made any changes or tuned up the engine lately? |

| I'd look toward fuel filter being "almost" clogged. Under load, the engine requires more fuel than can pass through the filter. Carb bowl starts to run out and engine slows. Bowl is replenished a bit and engine starts to speed up, repeat. Now the 30 minutes part points to a clogged gas tank vent. You may be having a combination of both contributing to the problem.... |
