Welcome to the Club, Kevin!
In my opinion, if an owner has time and resources to fly at least an hour a week, that is sufficient to keep the engine well lubricated and all the radios, etc., working. Not good for any of those things to sit without use. That being said, sometimes owners who aren't pursuing an advanced rating like you are, and have jobs and family responsibilities, just cannot break away for an hour every week. Also, some owners might fly a long cross country or two, then the airplane sits for two or three months without flying. I would rather have one flown for an hour every other week than one that sits for months without moving. Just my opinion based on my ownership experience.
Also, C-150's do have valve sticking problems because of the lead in 100LL. Many folks, myself included, use TCP in the fuel to scavenge the lead out and prevent the valve problems. Using TCP and leaning aggressively seems to adequately address the valve sticking problem.
Good luck on your search, and take my input with a grain of salt. I am not an A&P, but am a 12 year C-150 owner and flyer.
