MTD 18 Inch Rear Thine Yard Machine Tiller

After cleaning and reassembling the 5.5HP engine it still smoked.  The new rings came for it today and the plan is to do a quit re-ring job.  The engine should still be clean so all it should take is to open it up and replace them.  No cleaning required.  I do have a new pan/side cover gasket which I will use if needed.

There is a temptation to change just the oil ring because it has good compression and it would save the compression rings from having to seat.  But I will change all 3 rings.  The thinking is that steel rings should seat without degassing on an aluminum cylinder.

Stopped for lunch.  The new oil ring is much stronger then the old one.  Hope it does the trick.
