Thanks for the replies.

The machine has only had about 3 or 4 hours running time since we got it used from a big a dealer. we only use it once a month but its left to warm up once or twice a week.

I pulled the plugs out after fettling a socket to fit the tubes. I don't have a pressure tester for the coolant but I did put a compression tester on each cylinder. they all 4 pumped up to 150 and held for a minute or more. I don't know there is any antifreeze in the exhaust, plugs 1 and 4 were brand new but didn't look steam cleaned. I think there might have been a lot of water in the exhaust and the counterbalance is cold when the hot exhaust hits that it really sweats a lot of water. I put some rad sealer in it and ran it until hot and it all seemed to dry out back there so it might be ok for a time. I think I ran it out of propane as it wouldn't start this morning so I'll get a refill and report back as it's going to get a lot of use this week.


Started up. about a cup full of clean water condensation around the exhaust while it's still cold but dries right up. did I dodge a bullet here?

The propane stuff under the hood. looks like a regulator and maybe a solenoid valve.. gets frosty while it's running. is this normal ? it was hard to start with the new propane bottle and once it was very hot and tried to restart, it wasn't running great, had to baby it to keep it going. it got better when I turned the propane off and let it run out and after it was cool it was normal.
