Yeah, it was WAY messier/dirtier in there than I expected. Grime all over the place. It gets used up and down a dirt/gravel road so it doesn't surprise me overmuch....good idea.I would also say - hose off the whole thing - engine bay, cables, brackets... get all the dust and grime off of it, so you can see better, keep your hands clean as you work on it, and keep things from binding up with dust and grime.
I did a lot of cleaning when I was replacing the clutch seal a couple of years ago, and at that time I put in a replacement air filter.
Once we get good weather again (we have snow right now) I'll move it outside and do a heavy clean of the whole engine compartment, plus take a look at this line that's supposed to connect up between the pedal and the engine. Without taking the assembly behind the pedal off it kinda FEELS like the wire has broken/retracted, as I don't feel anything inside the rubber "gasket" in there. I need to take it off to see for sure though.
Given that I've had this puppy for over a decade, it's probably past time....
Thank you wally2q! I'll post what I find.
