Re: 1972 Johnson 2hp – low speed and idle problem

While the carb is off you may want to check the reeds and see if they are completely closing and not slightly held open by a critter or whatever.
Sure you got the upper and lower seals oriented correctly? Lip facing the center of the crankshaft?
The fuel level will give very minor changes unless it is drastically off one way or another. I take it the nozzle well gasket is in place?
Float not on upside down? Tab pointing down at the seat?
What happens if you take the needle out another turn or more for testing purposes?
