1984 50 hp Mercury carb issues

[steplift20]

My 1984 50 hp outboard is shooting gas out from the top but since it's a side mount it's coming out from the side that would be the top
When it's at mid to full throttle it's ok but at idle it leaks bad and stalls
Is there anything I can do without removing the carb?
I put in a full can of seafoam to 2 gallons of gas and am running it with that hoping it would free up what is sticking,but do far all it does is smoke a lot
Any suggestions?
