Hello. First post on this forum. Glad to have found it. I'm working on a Yale GLC050TGNUAE088, serial number E187V20019A with a Mazda F2 engine. Engine was running fine but was overheating due to leaking radiator and head gasket. I replaced the rad and the head gasket. The head was rebuilt when it was off, timing belt was replaced as well as spark plugs. Engine started right up after repairs and ran fine for 1/2 hour then quit. There wasn't any bogging or rough running, it just shut off. Engine turns over fine and ignition system is producing good spark. There doesn't seem to be any propane getting to the engine. It will kick on starting fluid. Swapped on a full propane tank just to be sure with out success. The evaporator is an electronic version with what looks like 2 electric lock valves. Any help would be appreciated.

A word to the wise- if the inlet port of the carb/mixer was loaded with enough "tar" to restrict fuel flow, than I would suggest either rebuilding/replacing the fuel regulator. That's where the tar residue was formed.
Also- make sure the fuel you are using is grade 'HD-5"- this is the fuel type reccomended for internal combustion engines- propane is not all the same. Don't be surprised if your propane vendor tells you different- many don't know what they're selling.
bbforks thanks very much for your reply. I have found the problem, the inlet port on the mixer/carb was plugged with stuff that looked like tar. Once it was cleaned out the unit runs well. Thanks again.
I'm not familiar with your exact model- could you send a picture of the regulator to my e-mail? If the engine starts on either than you are correct in your assumption that you have a fuel issue.
Did the regulator freeze over before the engine quit? Did the engine stumble then quit or stop like you turned off the key?
