Carb blowback??? Video Included

[Joker]

I just got my ski all together and running. it sounds like air is flowing back through carb (the hissing sound). Is this normal? If not where does the problem lie?

here is the video

All new crank seals and gaskets.
Pistons are orientated correctly.
Reeds are perfect with no creases, kinks, or bends. Thay lay flat also.

My kawi engine has that sound.. I'm pretty sure its from worn reeds as mine have over a millimeter of bend. Not 100% sure.

Reeds are perfect just pulled them tonight. No bends kinks or creases and they lay flat

First thought also reeds. Maybe your crankseals are leaking. Remove your flywheelcover to check it.

Brand new crank seals front and back along with all new gaskets. This engine was just rebuilt completely

 

[Joker]

And yes the seals are orientated correctly

 

[kswiatk]

Maybe the midshaft bearings or seals, or bearings or seals in the engine or pump?

I'm pretty sure it doesn't have to do with the driveline. It has to be engine related.

Hi, 1st post.....sounds like it's being starved of fuel?

Sounds normal to me

Ya that's what a few people have told me. I have never had it running without the arrestor so it sounds different

I haven't had a chance to get on the water yet. Went to the dells freeride and I had some spark problems. Cleaned up the grounds in the ebox and it seemed to solve it. I plan on water testing this week

Sounds normal.......does it idle on its own

 

[Joker]

Ya. Everyone's concensus is that it's normal.

Sounds normal to me, and rich.
