it was the carb screen I ordered a couple more. runs good now though after cleaning.
I'm glad that was it; your problem was a good reminder about "checking easy stuff", which I know I sometimes forget about doing.
I'm also a triple-filter user (jug, tank clunk, carb line) but periodically stuff magically appears on that screen. It defies any logic or explanation, but when you're sitting there looking at the "stuff", it's pretty tough to deny.
