Canned the idea of hex holing the cam for the Mechanical Fuel Pump, and if driven by the cam it´s done differently, basically pressfit of a hex 3/8 bolt head. The way I have it now i will add a drive to the Generator pad. for good reasons, pump will be in front of the engine rather than sticki´n out on the right side, and it´s logic when the intakes are on the left side with shorter lines etc, the cam cover will be left untouched.
The drive will be partial Morris Magneto H5 drive gears and flange and additional bearings/plate. Kind of a nice winter project. haven´t decided on the type of pump fitting yet, flange bolted or clamp I´ll decide after I got the drive design set. And sure a magneto would fit nicely but that would be another project when I´m satisfied that the mechanical fuel injection is the way to go.
