guessing you got a stuck needle/seat.

ur nglish tcher FAIL!

i thought that 2 but it wouldnt explain why the water is getting in the head without water getting to it

How did water get to the engine?
Was it on the hose? In the water?

Is this carb recently rebuilt?
Checked the fuel lines and pulse lines for leaks?

ya i always hook it up to the hose when im gona fire it it usually fires right up even cold so i didnt think anything of it. so i took the plugs out and turn it over till no water was on my fingers anymore and put the plugs back in. but they came up wet again!

and the carb is brand new just got it from PJS in brea only one trip on the carb

do you turn the water on first or the motor on first? if you had water sitting in your motor for that long it wont last much longer even if u get it running..

 

[smoofers]

Did you smell your fingers? Are you sure it's water and not gas? I think the stuck needle and seat is a good thing to investigate....

yup..on my old ski i had a stuck needle an seat and when ever i left it in the sun all the gas would go into the motor..there wasnt a very safe to get it out

 

[runninAmuck]

no its for sure water cuz the plugs show it its water bubbles its not fuel i know that fur sure.

i took it apart today and the exhaust and exhaust manifold were filled with water. so i turned it over without the plugs til there wasnt water coming out BUT the compreshion in the back cylinder is low now it was b4 they were both 150 psi WTF!!

Blown head gasket perhaps... do you start your engine first or do you turn on the hose first??

 

[runninAmuck]

I turn ski on first then the water but the ski died and i guess i didnt get to the hose fast enough. how am i supposed to get the head off i tried today but its on tight

 

[TnT]

if its on pretty tight one of the things you could do is keep the plugs in the head, pull the wires off and hit the start button. that usally worked for mine. There is one thing to be said about a 650sx, you sure get your wrench time in. :smashfreakB:

 

[runninAmuck]

alright il try that tomorrow and ya thats the truth! always workin on it but not as much as my old 550 that thing always had something going wrong. but saving up for a superjet right now looking to get one asap!!:headbang: thanks for the help man
