Default 1900 Hour Borescope

1900 hour Exhaust Valve Pics with the sub $10 camera on a piece of bent wire. Pics are not great, but they do the job:

#1 77/80 psi



#2 78/80



#3 76/80



#4 77/80

Mostly 91 Mogas (boat-gas here in Minne) and some 94 Swift fuel. Very little 100LL in the last few years.
