JRT,
You wrote: I think maybe the ring is stuckI ask: how much is no compression?
Have you carried out a compression test - both dry and wet? Until you do we have litle in the way of hard facts to go on. If there is no compression at all it could be a hole in the piston. It should not sound too good either. All these things are very subjective - no hard facts/information, so you need to find out as much as you can before deciding on the most likely route for repair. Personally, as it will have about 4 rings on each piston I doubt you have seen inside an engine? (as you say "the ring is"). No problem - everyone has to start somewhere, but understanding the basics is easily found in a book. When an engine sits an exhaust valve will always be open and like as not this may not be sealing correctly after several years. It may be sticking or the head/seat rusted (we don"t know the conditions it has been in for the last several years). It may have a broken valve spring, a burn"t valve (from before it sat), a sticking stem stopping it closing properly, a cam lobe worn out (so too little valve lift), a broken or otherwise valve rocker. The inlet valve may have been open as well and that too may have problems ( a cylinder with just an inlet valve open is usually protected by the oil bath aircleaner).
So upshot of all this is that is is useless soaking it in anything if the fault is a chipped valve or similar, so investigate a little further first.
Hope this helps.
Regards, RAB
