Wrong fuel & oil Mixture !!! ???

HI Folks, My dear son just poured some oil in a gas can with some gas in it and proceeded to crank and run my almost new Husqvarna 128 String Trimmer !  He said it ran for a few seconds then QUIT ! I'm sure it burnt up the engine ! Does anyone know where I would start to repair this trimmer ? I can pull on the cord and it still turns over without noise but will not crank. I poured all of the fuel out and poured in the proper 50:1 mixture. It still won't crank !  Weeds are getting TALL !  Can anyone help with any idea's ? Thanks in advance

Pull the muffler, use a flashlight and see if piston & cylinder is scored up.

I pulled the muffler and looked with a light and I don't see any scoring. I put an entire new carburetor on it and it will run for maybe one minute, then when you give it gas it shuts down !?!  I don't understand ? HELP PLEASE

Is there a primer bulb? Is it cracked?
Is there a crack in the fuel line? Is it attached tight?

What adjustments are on the new carb? Idle speed ok? Does choking it a little help? Giving it gas requires more fuel than idling.

Yes there is a primer bulb (brand new) not cracked. I have removed the entire gas tank, cleaned it and replaced all fuel lines. They all have the pinch kind of clamps and all are tight.
To Mikel1 : Yes the new carb has 2 adjustment screws. Is there a certain number of turns that are required with these screws ?

I believe you have a Zama, link below is a pdf adjustment document from Zama

Hey Mikel1 thank you so much for the PDF link. I'm not sure if it's a Zama but I will check first thing when I get home and see if I can get it adjusted properly. Hopefully this will help !  Thanks Again and God Bless You
