Short post this week

 I have done a little more sanding to the forward cabin sole however I am suffering from a bit of a low boredom threshold with sanding so I decided to fix an outstanding issue with the engine stop cable. Before I got the engine running I had replaced the original engine stop cable with a new one, the original cable was a bowden cable and it was getting pretty frayed, the new one is a solid Morse type cable but it did not have the usual ferrule at the end of the outer sheath and while the engine stop function worked perfectly well but when pushing the knob back in to reset the stop all that happened was that the outer sheath moved so the stop lever had to be reset by hand before restarting the engine, this all worked OK in fact it was probably a good way of immobilising the engine provided that you remembered to do the reset. On further investigation I found that the stop lever return spring was too long so that even in the stop position there was insufficient tension in the spring to return the lever. I started by removing the spring and cutting about three-quarters of an inch off it before forming a new eye on the end. Replacing the spring was a bit tricky as it is behind the fuel rack return spring but after some perseverance I managed to refit it.


I cut this much off the spring


Arrangement of the stop cable

As can bee seen from the above photograph that the cable connection to the stop lever does not allow for push pull operation. As a belt and braces I secured the cable outer sheath at a couple of points on the engine, the stop lever now works as intended no need for a manual reset. I had thought of fitting a stop solenoid but as can bee seen there is not much space and I am all in favour of keeping things simple where possible.
