Fuel Line Routing And Carb Gasket Replacement

1) I was having trouble getting it to start and stay running. Figured out that the purge bulb had a small crack in it. Bought a replacement. Started taking everything apart and also found one of the fuel lines had a small split in it also, so I bought new fuel line to just replace them all. I would like to know the correct routing to make sure I did it right. I didn't take pictures, my bad. 2) since I had almost everything apart, I thought I'd take off the carb and clean it. While putting it back together, I tore the back gasket. So I ordered both the back and front mounting gaskets from Ryobi. Neither one I got look anything like the originals. One is like a big rectangle and the other is kinda egg shaped. The second one, lines up with all the holes on the back side of the carb good. But when I line up the rectangle one, all the holes line up, except that the bottom right corner of the gasket hit the choke butterfly lever, so it won't lay flat against the carb face. I had a horrible time getting with Ryobi just trying to reach and talk to a human, I want to find out whether it's the right gasket and can I just trim it or try finding gaskets that look like the originals. That's why I'm contacting anyone here that might give me some insight on my issues without dealing with Ryobi again. I can't find any legible diagrams or helpful videos yet for either issue, gas lines or carb gaskets.Sorry I couldn't really make this a long story short. I really hope someone can give me some guidance. Thanks for the time, Mike Lawrence
