Even if the valve are working and shutting off completely the engine will run for several minutes before it runs out of fuel. With the liquid line filled between the valve and regulator there may be enough fuel to idle for 15 minutes. Another thing about propane is that it behaves a little different than gasoline in that it will migrate based on temperature/pressure rather than just gravity. Even with just the vapor line open, if the tank is warmer than the vapor line, fuel in the line will condense until both the liquid and the vapor line are filled with liquid.
If there is a problem with the valves it could be the cause of your sputter and lose of power. Valves not opening enough can cause lean conditions. Also if you do not have enough coolant flow through the regulator/converter assembly it will cause flooding as liquid fuel enters the mixer. A restricted valve or line will cause a temperature drop at the point of restriction. Any time the pressure is reduced on the propane it will absorb heat. That is why the regulator need warm coolant flowing through it.
With propane I would not go any heat range warmer than a Champion D15Y spark plug. Propane normally can use a plug one to two heat ranges colder than the same engine running on gasoline. It also takes more voltage to fire the spark plug with a propane fuel mix versus a gasoline fuel mixture. I would gap them in the .017 - .020 inch range.

Today's Featured Article - Maintaining Rubber Tires - by Staff. The broad use of rubber tires on farm tractors and machinery has resulted in a great saving in both time and operating costs since the time of steel wheels. There are, however, certain basic fundamentals in the care of tires that should be followed carefully if the owner is to derive maximum benefit from his or her investment. First and most important is to maintain proper pressure for the work at hand. Your best guide to proper inflation is the operator's manual or instruction book tha
