Yep, sounds like it's time for a carb rebuild.

Do a quick compression check before rebuilding the carbs. Had similar sypmtoms to yours and it was bad compression on one out of four cylinders.

    • Thanks Rebel, very good answer.  I've been keeping track of the pressure for a week, now. 
    • Hey Rebel, what do you consider low and high pressure?  Perhaps a stupid question, but I just got a weather station so now I can start tracking barometric pressure. Right now the numbers don't mean much to me, been around 28-29% in the south metro the past few day and I don't know if that's low, high or middle.
    • Low pressure signals a front moving in, (Bad weather, wind may be  from the east or north) which usually puts them "on the feed", can have some hot and fast action. Likewise, a swing in the other direction, a high pressure system , (wind from the west or south) which signals clear skies and sunny weather, may do the same. The key to me, anyway, seems to be hitting it just as either front moves in. An extended low or long high may result in poor fishing. Remember the old adage, which also has to so with the pressure: "Wind from the east; fish bite the least...wind from the north , the fisherman goes not forth, wind from the south, blows the bait in the fish's mouth; wind from the west, is when the fishing is best". 
    • Those trumpers sure know how to keep things classy.
    • Is it true, the lower the pressure, the bite gets hot? Or the higher the barometric pressure the fish slow down on biting? 
    • Is that like saying "the lights are on, but nobodies  home.?
    • Newsie's where reporting on how the lights are on in the white house at 5am...   "First time in a long long time.."    
    • Beautiful!!! Can I ask what your dry brine for the side pork was?
    • Don't forget to get your Dihydrogen Monoxide detector as well!!! That's what we really need to be worried about!! Especially on and around lakes!
