[QUOTE="Tom Gaynor, post: 13790, member: 4034"] [b]Testing motors[/b] Roy: you remind me that I once tried a Colortune plug in my Goldie, expecting to see the clear light blue flame of perfect combustion. What I saw was closer to a fireworks display, mostly yellow. Since it would readily pull 120 mph (it was in a Seeley frame, about knee high to a small dog, and weighed 300 lb) I decided to leave things the way they were. I should have said that the fuelling results on the Manx engine were at full throttle in top having spun the dyno drum up to speed through the gears. I wasn't interested in intermediate openings, since Race Plan A is to get to wide open within the power band as quickly as possible, to which end the twist grip is as progressive as a light switch.
