Aloha!

I've been enjoying the forum for a couple years and have had all my questions answered by using the search function. I'm stumped with this one though. My 94 Seca II suddenly has no power, a gutless sound, and a high idle. I stripped and cleaned the carbs to no avail. I haven't checked the valve clearances or the compression. I haven't run it out of oil; It doesn't smoke; the plugs look normal, maybe slightly oily. The engine revs very slowly, not as it normally does.

Any ideas? Need more information?

The video sucks, but the sound of the engine might give you a clue.
