if you've got a vice its fairly straightforward. Rig up a couple of bolts through the vice that you can hook each end of the spring onto, wind the vice out and open up the spring, then insert 2p and or 20p (if you are in the UK) coins or suitable washers in the open spring coils. It can be a bit tricky to keep the coins in so they need to be a tight fit and all roughly the same thickness. Once its full wind in the vice and lift off the spring with the coins or washers in place. It should now be long enough to slip over the stand and engine plate pegs with ease. Once on, pull out the coins with a pair of pliers, job done.
