Thanks for the great responses everyone! As I indicated earlier, I was pretty sure my mixture was the problem.
My friend does have the experience - I lived next door to him for years and now we're roommates. I have
learned a lot from him - which includes when to get a second opinion, believe me. Especially now.
@Maniac57: at one point last week I did change the plug and noticed a substantial improvement at first, but then the issues returned. This just re-enforces what's being said by everyone else here.

This is my favorite response so far - since you had "the exact issues" I described and resolved them easily by changing the mix.
SO. My work is cut out for me this weekend, and I will report back soon. I know that joining this forum was definitely a good choice - thanks again.
