Appreciate your help but i have no idea what you mean =/ The dogbones are the driveshafts right? If i spin the spur gear all 4 wheels spin, so i doubt its that!! But that nut you were talking about, with the spring, that wasnt tightened properly, you think that could be causing the problem?? Thanks
Edit: Does the clutch look OK btw???
The nut and spring that hold the spur on are called the slipper, it may be too loose, when you have it off the ground there is little to no resistance, when on the ground and the engine turning there is resistance and power, i would suggest trying to tighten the slipper nut (clockwise) a couple of turns and see if that helps.
Dogbones are drive shafts, there are cups that they sit in, these cups have small set/grub screws in them that hold them on a shaft, if they get loose the shafts will turn but the cups wont and the dogbones wont turn.
Clutch looks fine.
