[QUOTE="vibrac, post: 55094, member: 60"] the idea of the HD item is that there is no compression[U] untill [/U]it fires and shuts the door the remainder of the gas then turns the motor (against the second open head) where again spark fires the cylinder and that door is shut as well the motor continues to turn and then the next spark gives a full throw it also has the advantage that you can position the correct cylinder to be first in the firing line. having run my racers on twin and single plugs what marginal effect it gives me I would gladly loose for easy starting,there is of course one extra place for decompressor (or 10mm plug?) firing-breathing via a 1/4 hole in middle of head twixt the two valve seats (thats how Ron Kemps Flash ran 2 plugs back in the day) [/QUOTE]
