Default 1800 Hr Borescope Pics

On the way home from the dad's day fly-in @ KTOB Andi and I took Niner-pop-hotel over 1800 hrs. So I dropped the oil, checked the filter, checked compression, and scoped the valves.

Filter was clean, compressions were above 77/80 on all cylinders, and the valves looked pretty good - plugs were clean, too. #4 cylinder clearly got into the Spotted Cow........

O-320/Carb/EI/Mogas/Lots of LOP.

Edit: suddenly they appeared - maybe slow connection. ??

#4 and #1 look like twins - sure they are the right pictures? Look at the seat ring chips, and pattern on the valve.

Default Good catch

Bill - good catch - I replaced one of the photos - still not sure if they are all in the right place. They all looked fine in the end. - Big sigh of relief!

I forgot my cheapie micro brew scope at home, so these are from the ablescope that many people here have. Hooked it up to the smartphone and snapped away.
