Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I have a tecumseh HS40 engine that hunts at all rpm's low or high. I have removed the carb and cleaned it, removed all needles for cleaning, checked the float for leaking(seems ok), adjusted the float level with a 11/64 drill bit, used a base setting of 1.5 turns for the high speed needle and 1 turn for the low speed. Adjusted the engine while running at high speed and low. After this it still wants to hunt at all speeds.
What should I do next. Does it need a carb kit? Do I need to adjust the governor linkage. Any help is appreciated.

Do not know what my next step should be.
