She's A Slug..help!!!

It seems like you know your stuff pretty well, why not try changing out the stuff yourself? It's not that hard to set the timing and tune the carb yourself. Even if that doesn't fix it, you could still try looking at the other stuff. Auto work really isn't that hard if you take your time to get to understand what you're fixing. Plus, you'll have the peace of mind that you did all the work so if something goes wrong, it'll be MUCH easier to find the cause.
