Ok I did a lil more research and you have the Pro series Like I thought you had......... Forget all the other posts and Bull Butter about the plastic carbs....
You have the metal carb and bowl on yours .......... The bowl nut is your main jet and it has a hole in it on the top and a couple on the sides of it......
Take a wire from a bread tie and strip the plastic off....... Push that thru the holes and then spray carb cleaner very well to clean all the varnish out.....
Put it back on and start it up..... That is the main problem with most metal carbs.....
Let us know Mon Ami ~!~!
