Help! 2016 M8000 Procharger won't start.

New to me sled. Was running fine, drove into my garage. Wanted to setup temporarily for low elevation, went to Speedwerx and per their instruction I put a 42t upper pulley on, drained 91 fuel, added 110. In addition installed new spark plugs gapped to 0.020". Now won't start. Had very short pop on second rope, then nothing. Getting spark, checked plugs, getting fuel. Thought possibly flooded, pulled plugs and roped, small fire in pipe. Installed old plugs that I knew worked. Nothing. Let sit over night thinking what it could be. First pull this morning popped a little, then nothing. I'm at 1000' elevation.

Got it started. Believe it's just a rich pig. Drained 110 and put 91 back in, roped for awhile with a couple pops. Opened throttle half way and fired after few pulls. Put 110 in and rode a short bit, working fine. Better than fine she's a ripper! Very throttle sensitive! Gonna be a learning curve on this one!
