Shoot some Berrymans B12 into the airbox, pull the filter,,
Someone TOLD you that the carb had been cleaned. I don't know IF it was done or how well.
I would start by draining the carb bowl into a glass container. See what it looks like.
You living on campus? Any access to a garage or are you stuck in a parking lot?


It doesn't take long , trying to start one, and it NOT starting and running and recharging the battery to drop the voltage enough to still spin over at a good clip, but just won't fire the plug. Pulling the plug to see won't work, because the starter isn't loading the battery since there's no compression.
You can use a spare plug and see if it's firing.
