[AT] LP engine problem query

[H. L. Staples]

Grant the engine coolant must circulate freely through the LP converter. 
First thing I would look at is the coolant level.  Check to be sure there is
water going through the converter. Also you can  make a rough check of the
regulator by gently blowing on a small piece of tubing placed on the vent
opening.  You should be able to hear gas flow when you put a little pressure
through the vent opening. 
 
If you can get a repair kit for the converter, the overhaul is pretty simple
 The kit comes with both high and low pressure diaphragms and valves.
 
The units I have worked on had a simple screen as a filter. A site that may
help with identification of Vaporizer/converter and also a source of parts.

Subject: [AT] LP engine problem query
 
I feel very lacking in knowledge and embarassed that I cannot find where I
stored the ATIS messages that discuss how to fix a condition on LP engines.
I have a forklift that is running badly. The fuel ine from the tank goes to
a unit which I believe gasifies the LP liquid? In any case it is freezing up
for me. I am having fuel starvation on the engine. I assume that I need to
correct something either in the fuel line or the "gasification unit". The
flexible line from the tank has a great deal of wear/age cracks in it and I
assume there might be damage internally? Help!
    Additionally, the forklift worked fine until recently, but always with a
bit of unevenness. I don't know if that is related. A gasoline engine would
have a fuel filt, but I don't see one on this propane engine. Is that right?
    I will be working on this tomorrow and hopefully fixing it. Any clues?
Thanks so much!
