Hyster H90XMS SN: K 005 V 03382 Z
This machine will idle fine but when the accelerator pedal is pressed the spark becomes intermittent from the coil to dist preventing the engine from revving and cause it to surge. so far I have checked the vaporizer and mixer for tears in the diaphragm but none, replaced vaporizer. replaced ignition module in original dist. replaced dist. replaced coil, replaced spark plugs and checked for broken wires but have had no success. Checked oil pressure switch and water temp switch. Also this machine is not generating any error codes or check lights for this or any other problem. Thanks in advance for any help you may provide.
