I've got the first pipes available from Hauck (cpr's)

I need to know what they should be jetted at both mains and pilots,

also how high should the needles be set? and mixture screws

as well as what color of clutch spring should be in both primary and secondary?

I am running the sled in Manitoba the temps here are usually between -10 C (+14 F) to -30 C (-22 F)

I ran 50 pilots, 1.50-1.75 turns on fuel screws, 4th clip on needles with both shims on top of clip for the Pto and center and the mag I ran the clip on top and 1 below the clip, the mag one is the hot one, for mains I used 160,160,162.5. carbs still vented to the airbox.

I know jeff has updated his jetting some since way back then, you can call him at 414-698-6611
