Hi Guys, "Vixen" Engine number 10708 E, has just completed a 2 year body off and engine etc. rebuild and goes beautifully, however,have a problem with the starter motor currently on the second starter drive and the rubber drive has again stripped from the outer sleeve. Do not want to go to a hi-torque starter if at all possible due to originality and scrutineer's will spot as not in period for period events. Any help/ideas of where I can source a robust starter motor or starter drive other than the current supplier who appears to have a bad batch gratefully received. Tony
