Womp womp, the head leaked externally and possibly internally after assembly. My father is picking up a used oe head today. Will report back. We did have it running, but not enough to really make a judgement call.

Comparing to stock makes you appreciate the work that went into this mod for minimal gains. In the future I may try an save the hotrod head once again.
Why is this thing loading up with fuel at low rpm on the pto side cylinder ? Maybe I'll just drop the needle a notch and see if it cleans up.
Then I find this!
The mythical variable hight needle!
Today's test ride was a real roller coaster, with the needle in I figured I'd better at least pull the jets, the main was clean and someone had up sized it probably due to past mods. The low speed however was plugged up. Some cleaner and compressed air made it right and I did a quick spray down of the passageways while there. Did the same on the mag side cylinder and found similar jump in jetting. I will probably drop at least another notch on both needles next time there. It's still soft down low. But I did take the sled down to the river , found the tach to be inop (which sucks next time I'll bring my little one). Nailed it once and it started pulling hard once on the pipe, let off and it shut itself down with a clunk, I went to pull the rope and found it locked solid ...my father pulled up on my touring sled and I told him to get the tow rope .
I was sure the crank had piled up...
But when I went to remove the belt I found I could turn the motor over from the clutch , that's when I found the clutch had jammed itself open (one of the rollers is square instead of round) . Belt must have just been warm enough to be sticky and drug the motor to a stop.
A well placed whack released the sticking weight and I limped it back to the garage . Comp test shows great improvement on the pto cylinder (up to 125 ) and mag side a hair over 130. Decent number considering used pistons and some pretty real cylinder wear.
Time to learn to rebuild a clutch , I'll install a lighter spring and weights while there. I want this thing to launch violently. Skis to the sky!
This should give you a pretty good idea of what you are getting into. Looks pretty easy aside from the tools you'll need to buy/borrow or make.
I'm rebuilding a clutch in an Arctic Cat this week.
In reply to adam525i :
I had reason to believe that Nutter may be the man.
Now I know what I'm watching on lunch.
This got semi stalled as I thought I had a line on a cheap used clutch but the deal fell through. I'll order rollers , bushings etc tomorrow . Going to try rebuilding what I've got.
Well poop!
No use rebuilding this one. That crack isn't supposed to be there .
