Bought a used bike with a 48CC engine and I have been having the same problem as the this poster>

The old plug was as black as coal and I have also noticed unburned fuel at the muffler and the muffler appears to be modified (thinking about ordering a new one). Running a mixture of 32 to 1.
I have ordered a new plug, I'm sure there are no air leaks, I've adjusted the float, and noticed that the cover on the ignition coil is split with the wire exposed (waiting for a new coil) and a new motor mount for the back of the motor (currently missing/also on order). Unable to test the changes until the new parts arrive.
Can anyone advise what I should set the plug gap at? Anything else I should look at regarding the problem?
Installed the new parts today (plug, ignition coil, motor mount) and still having the same problem with the following changes;
If I adjust the float down (just slightly) I get no fuel though if I adjust it up (slightly) I get fuel running out the air filter.
