One cylinder wasn't firing. The plug was firing, sooooo, rings?
When I unscrewed the jug valve plugs, this is what I saw. Compression was 20 lbs.
Way too rich.
Can't tell for sure, is that a broken valve stem in the valve guide?
Don't worry, 5 out of 6 will get out down the road fast enough.
What id this on?
Where is the valve head?
OK, if you saw that and didn't remove the valve for the picture it is pretty serious. You gotta wonder if the valve is not there, where else would it be. Oh dear.......
Rob, model N?
It's on the K. The number six cylinder was sucking air at the intake, and running much too rich. We thought it was a carburetor issue until I noticed a few drips of gas coming from the intake manifold gasket at the back cylinder.
Meanwhile, it had carboned up so bad the valves must be leaking badly, there was almost no compression (hope the rings aren't leaking too).
I'm trying to get in and clean the seats, then lap in the valves (first time "lapping" for me). Dean Yoder is walking me through it over the phone as I go. The exhaust valve was pitted, but a fellow in town was able to grind both valves.
