Hello Rmi,
This sound very promising. My problem is that I can't find any reference to
this trigger coil in any of the manuals or newsletters. What exactly is it
for and whereis it ?
Are you also saying that maybe there is no need to upgrade to the new
starter motor ?
I am just about to order one from Lockwood ($299.-), but maybe I should
wait.
