After recovering from a nearly 2 foot snowfall a week ago, I am finally able to get back to the coach to try and get it up the hill to my new place. As some of you may recall, my issues started while on the highway, I lost power and was able to limp along at 13 mph until I reached my home at the time.
I have discussed this with several of you and as a result have replaced the fuel filter, and ignition module and coil. It appears I have healthy flow of fuel to the carb as I have robust flows of fuel entering the carb when activating the accelerator.

I installed the ignition module and coil today but no luck. It still ran quite rough and had no power going up a small incline. I let it idle for a while to burn as much of the old gas off as possible and will take several cans of fresh over tomorrow to try.

Could this be as simple as a timing issue? It has been years since I had to adjust the timing on any vehicle, the last was a '79 Toyota, and I am finding it hard to believe that the timing would go out in the middle of the highway. But I am game to try anything now as we really want to use the coach.

Is there a simple guide available to adjust the timing? Is this a one person job, or do I have to enlist help? I am at 8400 feet so is there a recommended + or - TDC I should be aiming for?

I wish I were more of an 'engine' guy!
