Hi All,

We have Linde LPG lifter model: H35T Sr# H2X393W02089 and problem is when we start it the engine is not smoothly run, like the gas regulator is providing the amount of gas is less or more to the engine and also when we trying to pick the load the engine speed goes down even it goes off.

After inspection I found leakage in gas regulator but unfortunately after repairing the fault is still persist. I have changed the spark plug, clean the carburetor, remove the muffler but fault is still persist.

One thing I have noticed that when I removed the plug wire from plug 2 and plug 3 the engine is still run in same speed but when I remove any plug wire from plug 1 or plug 4 (remaining three wires are plugged) then engine suddenly goes off. I have checked the current on all four wires they are ok. I have checked the pressure on piston 2 and 3 after removing the spark plug and pressure is good.

I'm unable to understand that where the problem is. Can anyone help me regarding this issue.
