This is how I did it:
Okay, do your tune up, plugs, wires, cap, rotor, fuel filter, air filter. Next, there are 3 modules you need to clean. 2 on the back of the engine, oval discs. and one on the front. Remove these. The left one you will need some high temp sealant before putting it back on. Get some carb cleaner, and clean them good, inside and out, spray into the tiny holes, into the diaphram, push it up and down to help it loosen anything. Get a small wire and stick it into the small holes to help as well. Clean both the back units the same. The front unit, remove the hoses, and pull it off. Remove 2 tiny screws that hold a bracket down that goes across the top of that. That might be hard to pop off the circular item, but either pop it around or wedge it out carefully. Next, clean it same way, with wire, carb cleaner, and move the diaphram. Clean some of the hoses. Check hoses, if they need replacing if hard, or cracked do so. And replace your O2, once that is done, do your timing and idle per the instructions on se-r.net. And it should be solid.
