Concerning starters; the regular sullivan basic starter with the 1:4 reduction Miller unit on 4 cell lipo will start a moki 215/ 250 easily. What is nice is the speed is much more appropriate for the Moki's. The top hat ignitions have been reliable for me for ten years. I run them on their own circuit at 5.5 volts. Here is the catch; I have them isolated from engine heat located on the other side of the firewall. I do have the new blue ignition unit with my 257 and it is fine. -tom
