Well! My truck has been sitting still for a few weeks now and I haven't gotten much time to start poking around at it and now my darn Ice Auger doesn't want to act right. Any help is greatly appreciated!

Its a Strikemaster Solo only a few years old. Used about 20 times.
I THINK I must have gunked up the fuel lines, but before I start breaking this thing apart and attempt to clean the carburetor I want to make sure I am not missing the anything obvious.
Prior to the past couple runs I ran UNLEADED fuel through it for about 5 tanks worth of gas before I learned I am supposed to run premium fuel. Before this it was brand new. Used it early this year and it now sat for about 2 months without use.

Filter is pristine and spark plug is new. Air line within the fuel reservoir is clear and still looks brand new (not deteriorating).
I prime it a few times, then start it and it usually starts up just fine. If I switch it to Run from Start within the first 10 seconds it will kill. If I let it go for a bit until it just barely chugs and I switch it to Run it will go VROOOOOOM and will idle for quite some time. Sometimes I had to switch it back to Start then Run when it would start chugging out a bit. Its like the airflow is messed up. MOST of the time if I have it idling and I then push the lever down to give it some gas it will kill immediately. SOMETIMES it will go VROOOOOM and run like a champ until I let go of the gas .. then it will usually kill. If you try to pump the gas it will die within the 1st or 2nd time pushing down.

Any easy things I should check?
