Only tried the propane for now (I bought a 40# tank for it). Started right up. Heavy, but with wheels easy to move. I can have a normal conversation 20 feet away from it. I'm happy with it.
Just received generator today! Added wheels, sturdy rubber feet, motor oil, gas, connected battery and she started right up using remote. Tried propane and generator ran great! Cannot wait to put to a true working test! Looking forward to many good years of service!
