    Ok Dan, I was satisfied with checkin the rings and doin some gaskets, but then I remembered something else that caught my eye. Does this look like an original connecting rod? First off the painted brown is perfect, and the bright yellow mark (assembly or reference mark) could this be 30+ years old? The engine is very very clean and bright inside everywhere. no sludge of build up or staining of any knid.The connecting rod has the # 492 cast into it. Just suspicious and curious of its originality. What do ya think?

      I see plenty of sludge on your top end studs
      Don't let that drop into your clean engine.

        yeah, thats all sand and road grit that stuck to the very oily engine and created a sandy paste. It got all packed in the fins in the cylinder head where the studs poke thru. I packed rags in the case openings and used a shop vac while I wiped the studs and case surface clean, what a gritty freakin mess. she was leakin oil bad. thanks man

          The conrod is fine. No sludge suggests it's had plenty of oil changes. It would do no harm at this stage to drop the oil pan and clean the pick up strainer though...

            It all looks good. The suggestion to drop and clean the pan is a good one since you have the time and it's that far apart anyway.

                dont know yet man have not measured anything yet. Just got a rolling chassis back together, just got to engine teardown and looking over phase. if ring gap is ok, I am just gonna strip and paint the engine, reassemble, adjust valves, carb o rings and be on the road........ Oh yeah, 1,2,3 sooooo easy... ha ha

                  turns out the advice to drop the pan and clean the strainer was a good one, the screen itself was very clean however the strainer cavity itself contained a serious wad of silicone "strings" that squeezed into to engine cavity as various components /case/parts were tightened down. I do not beleive it was really restricting oil flow, but certainly good to get it out. A bigger issue was I found a bolt right next to the strainer that had come loose and had backed out about three quarters of an inch. I have yet to determine what this bolt is (cannot find it in the manual. Will probably put a lock washer on it and tighten it down snug. Inside of bottom end looks as clean as can be also, the very slightest film of sludge on bottom of oil pan... looking good. thanks again

                    Actually the stroke comment was for Guy. Just bouncing off his pun about his wife's bore.
