Re: New to the group
Not quite sure what you mean by "blew a hole through the top of the cylinder".
Do you mean the piston? A hole in the cylinder could be a manufacturing flaw like a poor casting.
If the piston burned through that would be the result of a massive air leak or running the engine too long at WOT with no exhaust pipe/muffler. Carburetor clip position would not give you a lean condition sever enough to damage anything.
Oil content or fuel to oil ratio is important. As was stated, the kit recommended 16:1 is too much oil. The odd fact is that the more oil you use in the mix the leaner the fuel to air ratio becomes. Less oil alows more fuel so a 24 or 32:1 ratio actually enrichens the fuel to air mix.
