340 Duster oil looks milky

Thanks for the education, I’m learning as I go. I’m getting impatient but know what that leads to. I just really want to get this sorted so I can finally drive it. Do you think it’s possible there was still that much fuel still in it even after I changed the oil and swapped another carb on it. I did also notice the other day I had a crack on the ceramic of one of the plugs so maybe it wasn’t firing well in that cylinder and letting gas through to the oil??

The fuel in th eoil is from whenever that oil was run.
If you didn't use Blackstone, then go to whomever it was and get their analysis explanation. if you have doubts, then ask if if 4.4 is 4.4% or .044 % Huge difference.
if you can smell it in the oil then I think you know the answer.

IMO a misfiring cylinder is probably not going to dilute the oil to 4.5 %
The fuel pump is moer likely. Float bowls set way to high. Dumping fuel down the carb from a can. All more likely causes
