Re: Mcculloch 4hp no start

Set the high-speed (#1) 1 1/4 turn open from closed, # 2 at 1/2 – 3/4 turns open from closed. If you’re still using starting fluid into the carb, you need to open the choke – that flap across the front of the carb. But I’d go back to putting fuel (or starting fluid) directly into the cylinder and crank. If that doesn’t produce a pop, your timing is off or your spark went somewhere..
The lower unit takes grease, not gear oil. Use whatever is commonly used in non-shift gear cases.
