Well after languishing a couple of week I decided to try cleaning the intake ports. last time I tried barbecue grill cleaner, but I didn't like how it foamed and that is water base and corrosive. I found that PV blaster penetrating oil devolves the carbon. After scraping as much of the 1/8 thick layer with a screwdriver, blowing out the bits with compressed air, I filled up the port with PV blaster and agitated it with a cable tie, blew the stuff out and onto the fire wall, stuffed a rag down it and repeated the process 3 times. It seems reasonable clean, but I cant see from the top. Il'l try a mirror and flashlight or the endoscope. #2 is soaking now. If the deposits left are small and soft, maybe they'll do no harm passing though the engine.
Camera shoes that still needs some more cleaning in the hard to reach areas. The valve looks OK
