The main problem right now is the engine will not fire. It turns over and sounds like it has compression. 1999 Hyster H50XM SN:H177B10160W Engine- 3.0GM propane.

Has new tank of propane, has spark (new plug wires), new carb/mixer diaphragm, charged battery, new alternator (with all new wires from battery to starter, fused, grounded and still not charging).

sounds like a fuel delivery problem. I do not know a great deal about propane air mixing assembly's. I see two units here between the LP tank and air intake. I have yet to troubleshoot them although I do know the one closer to the water pump frosts over while running.

Any tips where to start or a link to service or troubleshooting manuals. thanks in advance
