25hp suzuki 3cyl help

[DUCKGOGETTER]

Guys i have a 25 suzuki 3cyl that i need help with. I changed the plugs, adjusted the idle on it, changed the seperator filter and it's just real sluggish. When you give it the gas it just boggs down and don't run as fast as it should. I think it needs a carb job, but i'm not sure. Any help on this would be appreciated, and if anyone does it on the side i would really like to to give my money to someone on this site, before i bring it to a shop. I'm located in lake charles and i'm willing to drive. I'm scratching my head on this.

Thanks, dgg
