Pulled the brand new spark plug. Was fouled.. another new one, turned it on and just tested it for a second, runs great. If its running too rich, what do I do to correct it?
I've also heard possible air leak?

So my YW50S is acting a bit funny..
It started a few months back (but I haven't had time to get into it until recently). On my way home, it died out, then when I got it started, it would bog down under throttle. Happened fairly quickly.
Now, I have changed the air filter, cleaned the entire carb, changed the spark plug, ran inspection on the petcock, and taken off the muffler to check for clog.
But HERE is the part that might mean something. It works sometimes? After I changed out the spark plug, it ran beautifully, seemingly faster than ever. I took it around for a test and about 7-8 blocks away, I stopped at a red light, and when I tried to throttle back up... nothing. Bogging down again.
Same thing happened when I took the muffler off. Initially, it was still bogging down.. then, 5 minutes later, I started it up again. This time it ran for a minute or so before I turned it off because its too loud for the city.
I'm going to try and run it loud again without the muffler in increments to see if it will work, but I don't think the muffler was clogged. I blew through it hard, used some compressor air through it, and there doesn't seem to be a blockage.
What is making my old Zuma behave like this?
P.S. I'm a newb.
