Camber on Hartman sprint

[philrock]

I'm setting up the front end on my '77 Hartman sprint kart. As I received the frame (pretty beat-up), caster is 11 degrees, king pin inclination is 13 degrees, and camber is +2 degrees on the right, +2.5 degrees on the left (+ camber meaning tops of wheels tilted outward).

The caster and k.p.i. numbers look reasonable to me, and even the 1/2 degree discrepancy in camber doesn't seem that bad, but I would have thought the camber should be negative, not positive.

Anyone know what the camber should be on this kart?

I'm re-building the spindles for front wheel brakes, so changing the camber while I'm at it is not a problem.

Phil,

How are you measuring a difference between caster and kingpin inclination?

[philrock]

I'm measuring caster, camber and k.p.i. with a very accurate digital protractor. First thing I do is set the kart level. I measure the caster and k.p.i. by putting the protractor directly against a long pin through the king pin hole. To measure the camber, I set the spindles so the stub axles are in line with each other, as seen from above, then use the protractor as a level, to check how out of level the stub axles are. The stub axle angle off horizontal, by definition, is the same as the camber.

Yep, that works, Throw wheels on it and go like heck !

Back to my original question - what is the correct camber for this kart?
