Hi everyone, I’ve recently purchased a 1973 9.5hp evinrude outboard that I saw ran when I got it. It came with a gas tank that I cleaned and put new mixed fuel in(50:1) and I went fishing with my friend but when we got to the river the motor wouldn’t start no matter how long we tried? We think it’s a problem with the carburetor needing a clean but idk so any help is great. Thanks!
