sorry don't have the model number at the moment... My propane forklift will start fine and run as long as needed. Shut it off and right away it starts right up again. Let it rest there off for 10 minutes or so and it won't start again till it cools down. I installed a new regulator. It's radiator is full. The reg is getting hot water through it. Full tank and in right position. Has liquid propane into the vacuum cutoff. It will crank during this time but it kinda backfires a bit while cranking. Like I said let it rest a good long while and it will start right up and idle great.
