RE: SWB ?
Two months for repair wow what happened to yours did you crash it?I have a two of there turbines and they start and run the first start every time.I did find out that if you have a fresh charge on the starter battery it will squeal on the first start and will take longer to get up to temp to start the fuel pump.It must spin it up too fast with a fresh charge all I do is shake the propane bottle a little and it will get more propane.
