No, it spins with some compression. Not as smooth as my 3 cylinder Yanmar on the John Deere. I am very suspicious about a stuck valve at the moment. It seems to be sucking and exhausting through the intake. I have got to figure out how to get this out of my truck and onto the ground. Such a pain climbing into the pickup bed to work on it.How does the motor sound when cranking? does it spin abnormally easy and smooth ( lack of compression pulses? )
The black goo leaking from the muffler joint indicates a fair amount of wet stacking has happened.
I've seen several 803's where the carbon buildup was causing the exhaust valve to not seat fully, resulting in Zero compression.
It was easy to fix, but wouldn't start otherwise.
If it cranks fast with little change in sound when pistons come up on compression ( combined with the pulsing you feel in the air cleaner ) leads me to think your valves may be hanging open a little.
