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

Looks like all that mogas is really causing havoc with the valves....

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

Where is best place to insert the borescope to get photos like these, bottom plugs?

That's how I do it, Derek. The camera is taped to a length of 12ga copper wire and bent into a tight hook.

Dumb question

What are you looking for? Excessive deposits or crusted on lead or carbon?

I just tore down my 2500 hr engine and the only sign off observable ware is a ring at the base of the cylinder you can feel with your fingers. Otherwise my cylinders look like that when you take the piston out.
