AUSTIN SEVEN STARTING HANDLES
A LOT of trouble has been caused to Austin Seven cars fitted with coil ignition owing to the fact that many owners will not replace the starting handle in to its correct horizontal position after starting up.
When
the handle is in the correct position, a flange on the starting handle
shaft makes a joint with a leather washer against the inside face of
the starting handle bush.
When
the handle is hanging down the small set screw at the end of the shaft
does not fit into the recess in the timing case cover, with the result
that the joint is not sealed, and wet and damp work in.
This, in addition to rusting up the starting handle shaft, works through the oil hole in the starting handle shalt bearing, and reaches the timing wheels and bearings, setting up rust formation. Dealers should pass this information on to their clients who, no doubt, appreciate any helpful tips that are given them. In this way more cordial relations are established between the Dealer and the client, to the advantage of each.
This is an article published by Austin to explain
to owners the correct position for the handle, it also relates to later cars
like the Box RN and RP. 90 years on and with the handle swinging freely has
resulted in a number of nose cones having the pin in the shaft wear out the
aluminum to hold the handle in place. Resulting in the handle at 6 o'clock and
not in the correct position of 9 o'clock.
Both the Bristol and the Cornwall A7 Club have
articles on how you can repair the cone by cutting a new locator for the pin in
the nose cone, but you will probably need a lathe. Or you could hold in place
with a piece of elastic or leather.
When I rebuilt our Ruby based A7 special with a
shortened nose cone, I used a Ruby nose cone (with a broken end which was then
cut off), but had a reasonable locator for the handle. In order to stop the
handle swinging, I used the Ruby handle spring shortened to enable me to
increase the pressure to hold the handle in place. So if you have a handle that
holds at 9 o'clock but won’t stay there, try using a Ruby spring and cut to
size.

Thanks to A7C for spring lengths.
