742 propane bobcat

[bunt1905]

i have purchased a 1989 742 bobcat. When i rev it up to work it cuts out and has no power, if i rev it down it will pick back up, until i work it, then powers out again seems better after it warms up and if i dont hold it full throttle. I was thinking of replacing regulator first then go from there. Any ideas will be lots of help thanks

Check for a fuel filter, propane is not 100 percent clean

had a service truck that did the same thing, ended up being the air filter was plugged and was collapsing the hose to the manifold causing it to essentially flood itself. Not to sure how the intake is on that machine but it might be worth a look.
