I guess this adjustment is independant to the spring tension one. What is the grub screw adjustment for? Is the spring tension screw adjustment the shift rpm?
I couldn't find a Mongoose manual.
Basic set up is to tighten the shift screws all the way in then 6 turns out, the other two screws are for setting the how hard you want it to shift, closer to the bell with out dragging the smother it will be,the further away the harded the car will shift, if you want the car to shift later, turn the shift screws in, sooner, loosen the shift screws. make sure you do small adjustments and the same amount for both shift screws, a good way to tell which screws you are adjusting is to remove the two speed from the housing and paint the screws, one white the other yellow so you can see them thru the shift hole in the two speed housing. good luck
