I had plug fowling happen to me on my first solo after a prolonged hold on the ground.
I half panicked and considered taxiing back in, then composed myself and remembered that it had happend before so I sorted it out and off I went.
However, I ran the engine upto full power for abour 1 min, but did not touch the mixture (which was on full rich) then went through the checks again and it was fine.
Was that the correct thing to do ?. (This was in a C152).
