I know is obvious but have you cleaned out the crankcase breather hoses &
flame trap.

If it coming out the the gasket or more likely the seal any kind of stop
leak won't work, such products only tend to work on pre-1960s oils seals
which had a higher natural rubber content, more modern seals are neoprene
like sythetic elastomers and the solvents and oils in the goop don't
penetrate into the seal material anything so well.
