No offense taken Eric (I really enjoy your posts by the way) but I'm not in over my head here.
I considered myself just above water when I did this:

to fix my Sportomatic diaphragm.
Right now I'm more frustrated than anything with the 'built for assembly line ease' design of fasteners, clips etc as I don't have a ready source for all that kind of stuff.
Dealing with a full tank of gas, at home in my garage isn't that hard, I admit. But in my present state of mind (I've been told my last day at work is the 19th of Oct, after 17 yrs) is not the best for dealing with this and it's something I hadn't thought I'd need to deal with since the car has been good up until now even under my admittedly neglectful care. Our Taurus pump taught me you don't let the tank go below 1/4 full for long as the gas cools the pump. I've treated the Mustang by this rule and here we are, 52k miles in and it needs another one.
Anyway, I put some starting fluid in it and it wants to fire off, so I'm pretty certain the ignition system is OK.
If I had a lift and didn't have to crawl around on hard concrete, this job might appeal to me more to save the money. But right now with the weather promised to be some of the hottest of the summer, I think I'll let the money go and take it to my friend's shop. I'll just consider it redistribution of some of the white collar welfare I've been receiving for the last 12 yrs from my former project.
