Clipping the governor spring

ive never heard of clipping a spring? ive shimmed out several to make them longer and thus have more pressure which is what a gov spring upgrade is, so im not sure what you are trying to do??? a loose spring in the pump will cause some SERIOUS idling/drivability issues. you want to cut the machine flat part of the spring off? the remaining coils will still have the same tensile strenght just an overall shorter dimension. so if you cu a 1/4 inch off you will haveto add 1/4inch of something to take up the space, once the space is taken up you will have the same and potentially a higher spring pressure because there isnt as many coils to bend/distord. 1 coil from this spring is still the same tensile as a complete spring however 1 coil WILL NOT compress, this is why i think spring pressures -could- increase which totally negates your assumed reason for clipping it.
is this like a tractor supply go fast spring that comes like 2 inches too long or something or is this a spring that you specifically bought for your injection pump?

Its a governor spring from bosch I think its intended for a VW pump so it's a few coils too long. Im running a VE pump

Its a precise measurement but if your close you can make fine adjustment with the fuel screw and idle screw. Also the throttle shaft can be indexed.
I wish i would have taken pictures when i did mine but i usually get caught up in the job and dont document it as well as some.
I feel mine probably is a shade too long but i dont want to rev it past 3200 much till i get valve springs. I have plenty of low end fuel but starts to go soft after 3k. Need fuel psi gauge.
