They were both pretty damn clean. 2 tiny specs of something in each one, but I blew them out when I put everything back together earlier this afternoon, so now they're 100% clear.

You got to have 3 things for the ski to run.
Fuel, Fire and Compression.
Are you sure your timing is correct? You say you got spark so that tells me you got fire, just could be at the wrong time.
Have you checked the reeds? if reeds are blown, you may not be getting good pulse signal.
Remove the air adjustment screws and squirt WD40 into them with the small tube. WD40 should start coming out of the venturi area. If not, you may have a blockage there.
Have you checked to make sure you do not have a crank seal that has blown out? This will cause ski to not run.

Take the Flame arrester off. Place hand over carb sealing it 100% and crank by battery about 3-5 turns but keep the throttle plate closed (no throttle). even back 100% off your idle screw so the plate is 100% closed. Remove hand. do you see a decent amount of fuel sitting on top of your throttle plate?

Electrics are brand new but are they all matched, particularly the stator and flywheel?
Any chance you got the white wires mixed up on the CDI?

I had an issue with my msd where it would spark awesome for about 5-10 seconds and then nothing. So every time I would "verify" the spark it looked good.

Yes, they are matched. All 62t electronics.

I'm with bk. Three things needed to run. Knock out obvious stuff first. Check cylinder compression.....
....but it does sound like a timing issue to me also.

pull the jets, specifically the low speed jets, and spray carb cleaner via a hose through the low speed jet holes and make sure the stream of carb cleaner comes out in the throat of the carbs. You said all the passages were clear, so you may have already done this, but this was my issue this weekend. The ski would run on primer but not even a rumble without it.
Also verify the check valve on the back of the block that covers the jet area is sealing.

Either Timing is off, you are kinda forcing the issue by pouring fuel in there, there will be enough fuel to get it kicking off, but with the timing being slightly off, it will run, just run like crap. Or, Your jetting is so far off that it cannot crank with the jetting specs. either to little or too much fuel at start up. I am going to say it is a combo of to much popoff and to much jetting. making it not what to fire off initially.

Brand = Mikuni

Quantity = 2
Main Jet = 125
Pilot Jet = 115
Needle/Seat= 2.0
Pop off 18psi
Pilot screw = 1.25
Main Screw = 1
XSR 46mm SBN carb set specs (XScream Modifications):
112.5 High with 5/8 turn out
117.5 Low with 1 7/8 turn out
2.3 N/S with 65 gram spring
# 70 Return line jet

Look at these 3 jetting specs for 46's. They are relatively close. But neither show running a 190 High Speed. Last one is running reverse jetting. These are way different than your setup. Try rejetting closer to the specs.

Keep it simple. Make sure the notch on the stator is lined up with the arrow on your cases.

Yup. Your key weight could have sheared.

That's what I did, lined up the marks. It's stock timing. That's kind of what I meant by "how far off could it really be", they make timing pretty easy to setup and you can't put the stator in backwards or the wiring harness wouldn't be able to feed its way out.
Also, it was a brand new flywheel key that was put in. All the parts were new when I put them in. New key, new seals, new pistons, rings, fresh hone, carbs rebuilt, new MSD enhancer, ZERO lightened flywheel that was fresh from him, fresh coil from JSS, new fuel lines, new primer. Basically, the only "old" parts were the crank, cylinder, cases, intake manifold, exhaust pipe. Everything else was new from a reputable vendor here.

Check that you have the msd enhancer hooked up correctly, then make sure you have a 62t stator and flywheel.
Hold your thumb over the pulse line going to the carb and crank her over and make sure there is a decent pulse signal.

Pulse won't blow my fingers off, but it's the same strength on both cylinders. It seems decent, and as I mentioned, there's fuel flowing through the lines, out the return, and back into the tank. I can also see fuel moving through my see-through fuel filters, one in each of the lines from the tank.
In terms of the flywheel/stator, what's the visuals to look for on each? And, would it run at all if they were mis-matched? I searched old emails and I'm sure that's what was ordered in each case, and what was marked on the packaging slips I have here in my "blaster" folder. So, as long as ZERO and JSS didn't screw up, I have the right stuff.
