I have ran a Lakewood scatter shield with JW 'wheel' and Bert trans in dirt cars with the Mopar mini starter and no nose support with very few problems. The engine was 408" w/12:1 CR. To mount/align the starter with the 'wheel', I had to make a shim plate to put between the starter and mount surface of the bell housing. On an occasion or two, we would have to re-position and re-tighten the starter as it would move a little and not engage smoothly after several hundred laps. Not a huge problem, but not 100% fail safe.
