Subject: Re: Automatic A/R mechanism for magnetos
I have completed the prototype of the automatic A/R coupling and have got the width down to just an extra 6.5 mm. It was necessary to remove the 10mm nut on the end of the magneto shaft but this shouldn't have any effect as the coupling is held on by a key.
Now on road trials and so far so good. About 10 deg advance at rest going up to full advance of 30 deg at 2000 r.p.m. More trials (when the weather gets a bit warmer !) and a planned full rolling road test in the New Year.
Colin - did you ever find the original you thought you had ?
