Alright well today I added more things to the "to-do" list.
Today consisted of cleaning the gas tanks and replacing fuel neck hose, breather hose, and feed hose. Turns out I need to pull out the sender and clean off all the gunk.
Also, I need a new starter. BUT..she turned on and the sound was beautiful!!

Building this toolbox took the most time out of my day -_-
Does anyone know where I can get a starter? I can't seem to find one anywhere. :(
