Sounds good, Paul. To me, opening up a Honda is a more formal process than, say, a Briggs, just like working on a Leggo project is more formal than a bent-and-twisted-tin child's toy. I tend to do it more carefully and respectfully, and find much less cause for irritation. I'm a very slow mechanic, but if there were nothing else wrong with it, re-ringing a Honda engine would take me about 2 hours once it was out of the mower and on the bench. That would include a test run. Be sure you do not fit the cheap aftermarket rings that are not chromed and have a cast iron oil ring - they work properly but last less than half as long as the good ones. If you buy good aftermarket rings (chromed top ring, chromed steel rail oil rings) they will probably cost less than half what you'd pay for Honda rings, and as far as I can tell, are just as good. I suggest you send a PM to roebuck about this.
