RE: Early Wen-Mac Identification
Sorry to say it, but it looks like the recoil starter is missing...?
The "gap" between the black flywheel / prop drive disc and the I. is where it shoulda been...you can see the alignment pin on the bottom strengthening rib....it would have gone into the back of the stamped steel (usually black) recoil spring housing.
You can see a notch for clearance in the intake venturi just in front of the spray bar.
