Superjet cranks but doesn’t fire

[jordanprice82@yahoo.com]

My 1994 square nose won’t start after full engine and carb rebuild.Setup is a ported 61x with Mikuni single 44 ada head 36cc domes Coffman pipe lightened fly wheel boyseen reeds. Ski cranks but won’t fire. Things I have checked
Electronics are fine I checked them on another ski good spark new plugs timing is set to stock tick mark. By passed start stop switch and still no fire just cranks fly wheel key is good and bolt is torqued to 70lbs battery fully charged

Carb is feeding fuel I can c it dripping out the Venturi check valve is good and when I try to choke it with my hand I can feel the carb sucking air tired using starting fluid and still no fire used genuine Mikuni rebuild kit

compression is 155 in each hole

Not sure where to go from here

If you have compression and fuel, the only thing left is spark. Have you verified spark with the plug grounded to the motor?

Yes I have and it was sparking that’s why I’m lost I thought maybe it was a timing thing but I’ve changed stator fly wheels and Cdi with all known tested and working units and still nothing

Plugs wet? You sure you are getting enough fuel? Put some straight down the carbs??

Swap your white wires inside the EBox and try. I had an issue once and this was the fix.

Tried fuel strait down the carb and nothing just cranks and cranks I’ll try the white wire thing

 

[jordanprice82@yahoo.com]

Tried the white wire still just cranks and no fire

Your cdi is toasted. Or a sponge?

Put fuel mix in plug holes. If it fires the cdi made a happy poopy. When it goes back to not firing at all hit up the jetmaniac and get a cdi.

Even if it's not cdi it will be at some point

I tried two different lightened fly wheels and one regular fly wheel and still nothing I tried a known working msd enhancer and a known working cdi unit still nothing I will try the fuel down the plug hole and c

I did not do an air leak down test seals were installed the correct way and I used oem seals plus a smear of 1211 around the cases but I will check that

Pulled engine did a leak down test it passed no drop in pressure lot of gas in the exhaust chamber tho

 

[jordanprice82@yahoo.com]

Got ski running tonight only thing I could think of is it got flooded trying to start it. had about 1 cup of gas in the exhaust flipped the engine over out of the ski and spun it by hand till the no more gas came out the exhaust manifold which was only alil then after it fired I got a ton of black oil out the back which is weird cause when I rebuilt it I washed out the waterbox and long exhaust hoses.
