The Bobcat has been running rough lately. I got home from Atlanta and had some time to look at it with him before I fly out tomorrow to Europe. It had low and fluctuating manifold vacuum. Played with timing and carb and just couldn't get it to smooth out. So I did a compression test. #1 60 psi, #2 30 psi, #3 150 psi, # 4 140 psi. Some time ago it sucked up crud in the carb and was running lean. Lean enough to melt an electrode on one of the plugs. I think it either burnt a couple valves or maybe even hurt some pistons. It's not blowing oil out of the breather or overheating so I hope it's just valves. I squirted oil in the hurt cylinders and checked again, Got the same numbers. Again I hope it's just valves. He is going to pull the head tomorrow. I called the machine shop and they said they could turn around the head in a couple days so we hopefully can get it fixed before the Hot Rod Power Tour. Not having good luck with all of our junk Fords lately.
