Timmerman "Shrapnnel-Knobben" mod et. al.

[Livolsi, Stephane]

This is great info.  Taking the leap into territory that I am only a bit
familiar with has anyone done or looked into wiring a potentiometer in
place of the resistor so that you could adjust the timing/fuel pump shut
off point as the situation requires....
Any thoughts or BTDT?
