Your main jet is clogged. The main jet is the "bolt" on the bottom of the bowl. You will need to drain the gas or shut off the gas first. There is a tiny pin hole in the threads that everyone seems to miss. It is only 1/2 mm and hard to see even when clean.

cleaned the bolt and worked calming down sputter but when in the run triangle it starts acting up again it even stalls like not getting gas.then put at fast setting and it starts the problem sputter again but runs. when using the thrower are you supposed to use the fast setting when clearing snow.

The main jet is still not clean. That tiny hole is still clogged which is what is causing the problem. And yes, the snowblower is made to be run at full speed.

Refer to the picture below, it is the top hole indy is refering to, the bolt may not look exactly like the one pictured, I use the wire from a twist tie to clean it. Have a good one. Geo
