I have a 2001 propane powered Linde H25T4585 S/N 351F02149525 that has been a wonderful machine until just recently. Two problems - first, the starter solenoid is intermittent. I have to rotate the key into the start position, turn it off and rotate again to get the engine to turn over. Sometimes it just won't engage until I put a battery charger on it. When it engages, it starts fine. No weird noises. It's not due to a bad battery - I put a new one in it and it still does the same thing.
Second problem - when it does start, it runs extremely (and I do mean extremely ) rough for at least 5 minutes in warm weather and 20 minutes in cold weather. Not enough power to do anything. Then as if a switch activated, it runs perfectly from then on. Will lift to capacity and runs extremely well.
Any ideas on what is broken?
I have replaced the regulator and removed the pressure switch manifold, so the propane tank connects directly to the regulator.
Plugs look perfect.
