Help!

[Confused!]

I need help installing a carburetor for my riding lawn mower. The diaphragms are useless an not to mention I have no clue what I'm doin I've never had to work on these things myself but now I'm lacking a choice if I want my grass less that 2 feet tall! Any advice is appreciated! Thanks!

Confused, so are we. Not many of us can help you unless you tell us the brand of engine and model number would help also.
