So, My pump is in pieces, if I'm going to do the Gov mod, it's now...Would there be much benefit of doing a 'mild' mod, with say 1.5-2mm of washers under the main spring? I want to keep it reliable (ish)Also, we have a yearly inspection in the UK called the MOT, and part of the test is to hold the engine on full throttle for a few seconds. How would the Gov mod affect this? It's an emissions test.Thanks guys.Steve
I stuck a 1/16" washer in place of the small spring and had great results with more power in the midrange.

I'd love to know how Reg is getting his motor through the test.
Many many many many times. Link in my signature, has all you need to know.I don't even have a main spring in my governor assembly! I have it shimmed completely solid with a ground down socket, custom one off piece :p lmao.I just got done messing with timing and pump settings today, and have noticed a huge increase.I've got it in its sweet spot right now. More power than before and little to no smoke at full acceleration! Unfortunately every pump is different and noone can copy another pump to receive the same results.. But yeah, might as well just shim it solid. You'll feel the motor run out of breathe before you over spin it.. Unless you miss a shift and hit 3rd! LOL
