well this evening i went to my lhs and picked up a new spur gear 70T E-z Plug Wire and glow plug because all those things were wrecked. so after an hour of putting those things in(im a newb) and i made sure that the spur gear had a bit of wiggle and well It started right up and I then noticed that i lost my throttle linkages screw the screw that goes on the main black peice , well i found another scerw different but it works, well it wont shift to second and bogs or revs reallly high in first gear. I still see a trail of blue smoke and i started to twek with the High speed needle..and also my brakes dont seem to be working very well and ideas?
