Model Clark CGC 25
serial # C365L-0087-9393

This is a strange one to me....customer says at times the truck won't restart and after the remove the tank LP couple and bleed the pressure from the line it will start.....
I have replaced the Model J Vaporizor and the Lockoff and solenoid and also the Beam Vacuum safety switch I also did a tune up on it...Cap,rotor,plugs and wires but the truck still has this intermittent no start unless you depressurize the line then reconnect it...had it happen with me today as I was installing the Lockoff and safety vacuum switch......started right up fine...ran it for 5-8 minutes...shut it off and after about 5 minutes tried starting again with a no start....depressurized the line and took some rolling over but it did start....anyone ever run into this....should of thought to check to see if spark was good when it wouldn't start but every time purging the line it starts???????
