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.

Hi guys,
First of all I'd like to thanks for kind suggestions.
After getting all your suggestion I had open engine head and found all valves are worn out. I installed the engine head after repairing but there is quite improvement which is engine is running smoothly when I'm not using any other function. I have observed following issues.
1. When using any hydraulic function (Lift, tilt up, side shift & steering).
Engine speed will increase before reaching the end position but at the end of position engine will suddenly goes off.
2. When drive.
Truck driving speed is smooth but when we completely press any pedal (reverse, forward) truck drives with jerk.
Something else to check is the intake manifold, there could be a vacuum leak that's effecting only those 2 cyl's.
Ok got it. I will check it
If cyl's 2 & 3 have compression & spark, then you'd have to investigate a physical problem like a worn cam or faulty lifters. I'd remove the valve cover & take a look at the valve train while it's Running
spark plug wiring order is correct
Have you checked your spark plug wiring order? Maybe 2 & 3 got crossed somehow. Most 4 cyl engines wiring order is 1-3-4-2.
