Pilot jet plugged.

You have a dirty carb. Pull it apart, soak the jets overnight in carb cleaner, blow them out with compressed air. Douche the entire carb body and all the passages with carb cleaner as well, followed by the compressed air. When you put the hot start plunger back in, make sure you've replace the plastic nut with an aluminum one from Zip-Ty so you won't have leak there. Also, lube the o-ring on the hot start plunger so it moves freely without sticking. Once all that's done, your problem should be gone...SC
