@Karl: Strange about the govenor spring. A lot of my customers complain about the max RPM. That's why i had special springs made for me. Got now 3 different types. On the test bench I gave me the following results. Fuel cut around 4400RPM, 4750RPM and 5100RPM. When I'm sending them out I and there are no questions asked I place the 4400RPM spring and on special request the stronger ones. (I realy like the uncaged covernor.)
Why do you picture an obviously used one if they are new?
