Mine runs poorly when idling. I did, however, do what you have done but no soap. I am going to run the compression test again, only this time properly. If I get what I think I will, one cylinder substantially lower than the rest, I am going to guess a burnt valve or at least one going that way. Does have some compression so might not be totally damaged yet. Good time to fix it. I have had one before. The PO said the valve seats were hardened but I am beginning to doubt it. I had to run alcohol gas for a while but now run only Alky free; not sure that matters. Might need to find an additive or something. Anyway, if I do go that route, I am going to get hardened seats if I can. I was borderline lean for a while so that might not have helped. Even though I think the compression will be low, I do not burn oil, at least in any volume you can see. Idling it is clean, deceleration produces no smoke nor acceleration so I have a tough time blaming the rings.
