HELP! CR80 carb/fuel problem

When took the pumps apart they other day they were spotless. I can’t answer the question about the readout because I’ve been busy trying to keep it running enough to get off the line and out of the way but I’ve since swapped out the cdi to be sure and it didn’t make the problem go away I like the silencer suggestion I hadn’t thought of that so I’ll be on that tomorrow

Thanks \m/
