Re: Mcculloch 4hp no start

On the second tier of these posts, there are two pictures of your installed carb. In both pictures, the mag lever is in the stop position. In this position, the cam would be as you show, in relation to TDC. It would be firing after top dead center. Move the mag lever all the way to port and you should see the relationship to the TDC position change. The points will break near or before TDC. THAT’S where you want to try to start the motor.

If that lever doesn’t move, then it must be seized.

Long live American manufacturing!
