Engine won't rev

New fuel with seafoam, pampered engine. Ran flawlessly for the last 5 outings. Today at the end of the ride it died and wouldn't throttle up over idle. I slowly idled in.

Have it in driveway in a trashcan. Wont run properly still. Engine pristine inside and out. Garage kept.

I'm leaning towards fuel line/gas tank. Ideas?

Run a compression test to see if all cylinders are even. Check that all cylinders are firing and plugs are good. Check fuel for water, can you keep it running by pumping fuel primer bulb or bumping choke? May need to remove and clean carb.
