Mate mate mate, to be honest the fella in the photo runs 35s and was given a i:6 ratio reputed to be all in good order and ready to go, but a little bit of end play in the rear output shaft, and backlash not the best, having removed his 1:4 curiosity (killed the sodding cat) said just remove the 1:4 output shaft and see what that was about, no movement, Nada, nixies sod all movement, backlash perfect so IS the 1:6 any good, I have a 1:2 here completely refurbished, we'll have a quick butchers at that, loads of play in the bearing backlash good, and now there's me thinking I've been diddled, I HOPE YOUR PAYING ATTENTION HERE, YOU DID ASK, I have a knackered 1:4 that after all the aforementioned tests worked out better than my refurbished 1:2, I was on my way round to the fella that sold me the 1:2, I'll try not to bore you anymore, at one point we had 7 on the bench all different backlash and different end floats it looked like something out of I robot, that bit in the film when they are stood in line, just one of them is dodgy, you just dont know which one, you know the bit, to the point I think this photo was close to midnight and all completely confused, we went our ways, the upshot was we put his new but unsure 1:6 in on Sunday morning throwing caution to the wind and it worked perfectly, no rattles and all good, so basically the moral of this story (if there is one) don't listen to Ashcroft, throw it in and hope, we're still buggered if we actually learned anything from our day other than I'm still not sure if my refurbished 1:2 is any good, YOU DID ASK
