I have reused the copper covered gasket a few times removing the carburetor and putting it back on. I'll try some sealant on that. I believe I checked the gas line where it goes in the carburetor and it was sufficient but I will check that again. I think it's good as nothing changed there since the first time.

Thanks for replies and when I figure it out I'll make sure to say what problem I found.
