Everything runs fine, but as soon as I pull down the throttle, the engine starts to stall.
Need some help please..

Could be a clogged fuel filter.  Do a search, there are a couple good threads here on taking care of that.

Classic symptoms off restricted flow from the pump; everything is fine until you open the faucet all the way, then it just can't supply the fuel as fast as it used to.

Thank you for the help. What about the spark plug?

Probably not a spark plug issue but might as well change it as they cost a whopping $1.98

Yeah, although it seems like a big mission to change it and no tool of mine seem to fit into the chamber..
