02' F60 problem

[captflossman]

I have a carbuerated F60 that hesitates quite abit while running. It has no trouble starting or idling. It seems to hesitate a little on the holeshot and while running it slows then speeds up. It doesn't do it when I am wide open all the way but it does it pretty much throughout all the other ranges. I can watch the rpm drop and rise maybe 50 rpms when it happens. It kinda feels like it runs out of gas for a second. It never stalls. I just changed plugs and ran 2 shock treatments of sea foam with no smoke. Does sea foam treatment clean the carbs or what is the best way to clean the carbs? Can I remove the carb assembly and spray deep creep in the bowls?
Thanks

It probably needs carb removed and cleaned. The best way to clean is to disassemble carbs and soak in carb cleaner then blow out passages and jet with compressed air.
