Source for instructions to replace carburetor

not sure about your particular model but you tube has plenty of videos

Thanks, I'll take a look.

I just did a quick search for any instructions for how to replace the carborator on your model and I didn't come up with anything of that sort.

You may want to take a look at the correct manual for your lawnmower at the link below if you don't have it already. It may have a few diagrams that could be helpful.

how do you know you need to replace the carburetor? Is it broken or cracked?

Thanks, I did have the manual and will be using it when I replace the carb.

It seems to be leaking gas from an unusual place so I'm fairly sure there is a crack there. Thanks for the reply!

Carburetors don't usually need replacing unless they've been sitting forever. My guess is that you may have a float that leaks gas into the throat of the carburetor, and that gas is leaking out of a bad gasket. I'd think twice about replacing a carburetor because they can get real expensive if you don't have a good used one on hand. Rebuild kits are only $15.
