Tough one this...ive been looking for a sidewinder tool for a while now.its a racthet screwdriver with the usual changeable heads but with a right angle head and a small t bar on the end of the handle to operate the rachet....small and lightweight idea for this job.....otherwise, as you know its carbs off a small tweek and back on again, reapeted untill its "just right"....very time consuming....was'nt aware of the yam tool, do you know how much they are ?
