Hey guys - first off, thanks for any help, it's appreciated!
I've got a '76 with the inline 6 motor that was once sitting for quite a few years in a field. I'm not sure of the entire history of maintenance, but it still runs and drives (after fixing a few things here and there). I bought it from my girlfriend's grandparents, and they owned it for 20 years, but it was sitting for 4 or 5 in a field after they couldn't drive anymore... The valves were chattering, so I took the valve cover off and went to fix it, and this was what it looked like:
What's the best way to clean that up? It runs strong, only 72,000 miles on the motor, but I have a feeling this would help quite a bit, as well as overhauling the carburetor, which is next. A few people have told me Seafoam in the crankcase, however I've read bad things about doing that - but what do you guys recommend to clean it up?
Thanks a ton for any help!
