I'm a little stumped, so I thought I might come to the people with a little wider knowledge base than mine. I'm in Kent, about 350 miles from my toolbox. :-\
After a camping trip, fully loaded up as high up as I could get on Mt. Rainier, I was having trouble. It was stumbling and lurching when I tried to maintain a constant speed, but would act fine while accelerating/decelerating. It didn't act weird until I got gas about 30 miles from the base of the mountain. It would idle decently at 700
I changed the fuel filter, put a bottle of carb cleaner in the next tank of gas and sprayed down the carb. It didn't seem to help much, so I popped the vacuum line off the vacuum advance and it stopped missing, and would run fine at any RPM. when I pulled the throttle cable with my finger over the vac line, it pulled more as the RPMs increased, and I didn't find any vac leaks.
I've been driving around Kent/Covington without it hooked up. I noticed it had slightly less power(not like it has it anyway), and I lost a couple MPGs on the highway, but it was running fine, with no pings or misses.
Now my current issue, after a couple hundred miles with no advance, it's starting to act up , missing randomly at a broad range of RPMs, regardless of throttle input. Is it possible that the advance is just clogged, and whatever was holding it up came loose while driving around? Or do they just have a tendency to bite the dust after 213K miles? I haven't had any problems with it during the previous 8k I put on the car since I got it.
I'll try to clean it out in the morning and hook it back up to see what I get. A couple days ago I put the hose back on and it ran terribly again, but was fine instantly without it.
Also, before leaving timing was set at 8 degrees BTDC at 700rpm, and it was fine for about 1500 miles.
* could it be pickup wires under the cap? How'd I go about testing those without putting a new disty on the motor?
