Apart From Powertune Is There Anything Else I Could Try To Un Gunk My Sticking Piston Ring Could I Use Asitone As Want To Try Other Things Before Strip Down

I would have thought any chlorinated solvent would do the trick.

Alternatively petrol, turpintine substitute, etc etc should do it.

Diesel is a damn good penatrating fluid may be worth a drop squirted into the cylinder, before starting tuen engine over with plug out to dispel excess then go for it.

Good luck with the motor

Petrol is one of the best solvents known to man.....

Or you could try wd40 or Plusgas.

depends what's making it stick... ...I'm not an engine guru but since it was apparently running well beofre standing for 5 years - is it not more likely to be corrosion than carbon deposits?

I'm intending to agree with Polwart here. Scoring of the cylinder wall would be on the list as well I'm afraid. I take it you've run it by now?

One tip I can give (not very scientific though) is to squirt some oil into the offending cylinder and compression test again. The theory is that if you still have a low compression reading, then there is a major problem (broken piston ring). If compression goes up to what it should then might not be a serious.
I must admit that I would have stripped it by now, but then that's me!

How about popping off the exhaust manifold side of the powerhead and having a look at the rings from there? You could get a good idea if the piston is scored or if its carbon or corrosion thats sticking the piston. Some motors have good access to the exhaust side with little trouble. Worth a shot.

Be very careful! I reckon (and this is purely an educated guess) that acetone could strip all the oil off the bores in a nanosecond. I certainly wouldn't start pouring random fluids down it's gullet. Powertune is a known quantity and designed for the job.

You could try redex I guess, but I tend to agree with hightower - I'd have the spanners out and start investigating.
