ya... once the intake is off you can just see the pistons.
what does the pulse line do? it goes from the crankcase to the fuel pump...... it's not pulsing and I'd imagine that's not good.

Re: fucking jet skis
 

Oh I see. That pulse line is what "drives" the fuel pump.

Re: fucking jet skis
 

and so if there is no pulse..... what could be the cause?

Re: fucking jet skis
 

Blown crack seals

I'm a Kawi tech, I think I can help. Sorry I haven't been paying real close attention to this thread. Let me re-read and I'll come up with something. I know JS JT JHT models well. :)

Okay, I'm back. What did it comp. test at? Did you do one? You should be looking for about 120 (+/- 5) psi across the bank.
On a boat that old, I wouldn't be amazed if the crank seals are dusted. :-[ Do you need a walkthrough on a crankcase pressure test procedure?

Re: fucking jet skis
 

ill do a comp test tomorrow or thursday...... untill then, wish me luck

Re: fucking jet skis
 

I don't know where I've heard that before???

Re: fucking jet skis
 

ok so I did a compression test and it's about 140 on both cylinders.
I checked the crankcase pulse line and I think the first time I just expected it to pull harder. I do feel a pulse.

I try to crank it over and it kicks/shoots exhaust out but then it makes the awful screech sound and pauses for a second while im cranking. could it just be my starter? I have fuel, spark, and compression. It tries to start and just doesn't. I have no idea guys... help!

I tried to start it up again and it's right there. The problem now is the screech sound it makes. It fires and almost starts and the sound just gets more frequent as it gets closer to starting.
It's a really weird sound that's hard to explain but it happens and then the motor stops cranking over for a second. then it keeps trying to crank until it happens again.

Re: fucking jet skis
 

have you cleaned out the carbs yet?, or make sure there is no trash in the peacock(sp) the on and off switch?


have you tried to crank it with either yet?


maybe a electrical problem?

Maybe bring it to someone who knows about 2 stroke small engines?
