The fuel going into the crankcase is already atomized and mixed with air and oil. adding any additional fuel after the carbs will only over- richen the mixture, and diesel fuel (which is a bit oily) will foul the plugs.
The exact opposite of an vacuum leak in the crankcase or carb boots.
Extra air will make the combustion chamber hotter -melting pistons and such. Extra fuel will make it colder, less likely to burn and put deposits on the plugs.
Clean out as much as you can and run it, be prepared for a new set of plugs or two.
