Thanks for the input. Was wondering if there might be some buildup but it does seem to be slowly getting better running lots of seafoam. Just wanted to make sure I'm focusing on the right problem & that it isn't something else. I read somewhere on here that some have recommended running some racing fuel thru it to clean it out & just keep at it. I can get some next time in town. At least it runs, so fuel+additives go thru it allowing something to hopefully clean it out. Really don't want to be investing in another carb unless absolutely necessary.
I found helpful pics that CloudDriver posted Oct 2011 on this very site. If you have some others that might help they would be appreciated

Your input so far seems to be pointing me to carb being the issue or at least main issue.
