Doing a little maintenance on my primary and noticed the spring was broke. The sled is an '85 Formula Plus. Does anyone know what colour or weight the spring should be? Tried Royal but they said it was discontinued.[/b]

They have online microfiches of snowmobiles there. I quickly checked the Skidoo ones, however they only date back to 1987. I don't know how different, if at all, there would be between those year sleds, but according to the microfiches, you would need a yellow-blue spring.
