Re: New misfire - sticky valves?

Just took off the intake and here's what I found. Guess I was lucky that it landed and stayed where I found it. The rest of the valve assembly looks good. Anyone know where to get a new C-clip?

Re: New misfire - sticky valves?

Thanks for the tips guys. I just ran a compression test on all cylinders. All cylinders reported in at around 75 PSI except for #7 which reported in at ZERO. I guess that's the culprit. Any advice on...
