Hyster H80XM LPG

Hi, I am having a issue with the forklift stumbling. Starts and runs fine but at idle it will stumble like it's about to die for about 1 second, then run fine again. This happens about every 5 to 10 seconds. If I give the unit throttle it will rev up, but it still stumbles, about every 5 to 10 seconds at higher RPM's.

Thanks in advance for the help.

some of these units have what they call a dashpot on the throttle.
if it is not adjusted correctly it can allow the throttle to drop too low or have a surge in it like what you are describing.
On the higher rpm's i'm not sure what that might be unless it has a mechanical governor on it, if thats been tampered with it might be out of adjustment causing that surge.

Fact of the week
Foundling hatches are safe, anonymous drop-off points for unwanted infants, allowing parents in crisis a way to surrender a baby safely without fear of punishment, ensuring the child is rescued and cared for. The concept started in the 12th century, was abandoned in the late 19th century, then reintroduced in 1952. It has since been adopted in many countries.
