[AT] LP engine problem query

[Francis Robinson]

	Notice if the regulator vent is clear before you blow in it. If it is
plugged that may be your problem. You wouldn't think that the slight
movement of the diaphragm would need to move much air but I have had LP
heaters go completely out when some bug wove a tight web over it. I have
also had them go out when water dripped on a regulator and it froze across
the tiny screen of the vent hole. Just a thought.

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.

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!
