pls help! weird sounds during startup

yo guys, been having some trouble with my grizzly 660, i noticed when i was pushing the startup button, it was making a groaning sound? yeah, weird. this all was happening when the engine was turning over, not when it fired up. this may not be related, but i noticed a strong fuel getting strong every time it groaned.
i know this is super weird and you probably never heard of it, but help is appreciated!
