I have no idea what year this forklift is, it is an older model for sure. It is an LP fueled model and the LP is fed into a round two stage valve prior to being fed to the carburetor. This "valve" freezes up quite quickly and I am not sure if there is supposed to be engine coolant flowing into or around this "valve" to keep the valve from freezing. When it freezes up the engine stops running and you have to pour hot water on the valve to get the engine to start again, this happens over and over. I am at my wits end... Anyone know or remember anything about this set up and what I can do to stop it from freezing???? I am fairly certain this LP system is factory, but it could be aftermarket stuff... Any help would be greatly appreciated! Thanks dale_k
