It is a Homelite.
I checked the filter, and it is pristine, since the thing has hardly been used.
I don't understand why it would have gone out of adjustment just sitting in my garage. Clogged makes sense.
I have turned the choke off once it's warmed up, with no effect.
I will pull the spark plug and check to see if its fouled.
Then I'll pull out the filter and spray some carb cleaner.
I'd prefer not to pull off the carb, since I'm not that handy. Well, I'm sure I could get it off, putting back on properly would be a bit of a problem.
Thanks for all your suggestions. I hate to take it to a shop if it is something I can fix myself.
