I hate to keep asking you guys for help, but I just really don't know what I am doing! Sorry.

What are some possibilities that will cause a rich mixture?

-Having the choke pulled out
-Adjusting the screws on the carb
-(don't know any more)

I think my ski is running rich and that is why it keeps bogging down, but I don't know why it is running rich! I haven't adjusted the screws at all and I don't think the choke could have gotten stuck this whole time...
