2005 King powder or plugs???

[Drlsldr]

Broke trail for my 13 yr old the other night- great snow!!! Sled started to cut out or lose power. Fun sled but always something it seems... I have heard of the powder bog? Checked plugs, one dry, one wet what would that indicate?
Trying hard to learn about these damn machines! Any thoughts much appreciated.

If not a fouled plug, you may need to drop a jet size on that side or both depending on the plugs color. A lot of the powder bog can be closer jetting corrected.

Thanks, Sled is EFI? i'm clueless about adjustment or issues with that. Was Thinking the powder bog was due to plugging of exhaust or poor air flow?
