If its CONSISTENTLY rough, you could try running it with the lid off.
Easy to do but best to have a fire bottle there, though I've never had an issue doing it.
Not good if it has a tendency to backfire or is possessed and mad at you personally, which can happen.
Leave lid on with screws (and air cleaner stud) OUT, and choke rod clip off.
Fire it up.
Come back out & lift the lid off. You can see where the wet float level is and any goofy stuff going on.
Don't gun it or any drama of course.
You can push down each float SLOWLY but be ready, they will spray up!
Then see if they recover and seal.
Hardest thing is the float acting up intermittently. In that case I just try another one.
