There is a secret Land-Rover owners trick to using the starting handle (unless you just use it to turn over the engine to do the tappets). You get 4 large penny washers and tie them onto 4 3 foot lengths of hiry string.
You then put the penny washers between the valve top and the rocker for the four exhaust valves. You then wind like f*ck (no compression asthe valves are being held slightly open). A friend or helper, then tugs on the string to ping out the penny washers when you have got it spinning fast enough, and just before you have a heart attack.
Job's a good un.
