Exactly the same as mine brilliant bit of kitAfter nearly firing a 1 series M Sport spring through the garage roof I gave up on the old style wind-up ones, picked up a floor standing hydraulic compressor which has done two E85s now.
Not the easiest with M-Sport springs (very little to grab onto!), you're more than welcome to borrow it and see if it works for you though.
