bobcat 853 motor keeps dying down

[ireland]

Hey everone i have a bobcat 853h with a power problem. Its slow to start but when it fires up the motor dies down. Even at full trottle the motor is almost cutting out. it will increase in rpms for a couple of seconds and dies down again. After about five minutes of up and down idling it will then increase back to normal and then can be operated like normal. please any help would be great thanks

Sounds like air in the fuel supply. Try starting it on a different fuel supply by running a hose from the inlet side of the primer bulb to a clean jug of fuel. If it runs better then the problem is from the bulb to the tank, if not then from the bulb to the injector pump. Might even be the primer bulb.
