So your manual if I recall should say something like it's not practical to check compression because of the ACR automatic compression release. However, it's been said before that it can be checked by using a rope and turning engine backwards. Or, since the ACR keeps exhaust valve slightly open until you hit 650 rpm, you could adjust the exhaust valve to overcome the ACR so that it closes then check, but then the SG probably will have a hard time turning the engine.

Since you have it running somewhat better. I would run it for awhile checking oil consumption. I think you have a valve that not seating fully. Running it may clean that up some.
