Questions?? 2 speed Troubles...

Hi there,

Im am having some problems tuning my brothers 2spd. I noticed the adjusting grub screw had fallen out whilst driving. Its been replaced(aswell as the spring and the ball bearing), and no matter how small an adjustment I make, It WONT change into second!

Is there something Im missing or havent done??

Any advice would be great.

Probably a stupid question, but how do you know if it has shifted into second gear?

Thanks

How do you know if your car shifts into 2nd?
Pick up the car and roll the throttle slowly and listen for a tone shift.

What I do for 2 speeds is tighten the screws down then back each out 5 turns. Roll the into the throttle slowly until you hear the tranny shift. From there loosen or tighten your set screws.

Is there one or two adjustment screws? My bet there is one (finger type). If the finger comes out too easily it will shift almost as soon as the gears move and you cant tell it happened. It will be in second all the time. If it is too tight it will never shift into second.
