Do you have the older style carb that doesn't use O-Rings?

 

[tumblingtwerp9]

i think so

post some pictures... I am sure that there is a simple explanation as to your problems since there are a gazillion people with the same carbs and no leaks

 

[tumblingtwerp9]

what exactly should i take pics of?

 

[Matt_E]

The inside of the fuel pump and how you're assembling the parts.
Are you using an O-ring type rebuild kit on a non-O-ring carb?

 

[tumblingtwerp9]

their arent any o ring slits in the carb.
the gasket kit im using doesnt have the oring parts.
I used the same type of kit on both carbs and just the one is leaking. I dont know what it could be.

Use only genuine Mikuni carb kits! They even come with a carb assembly diagram to see how they go together for old and new style carbs...don't use aftermarket junk for performance market.

The carb was not leaking before you rebuilt it, was it?

It's either a faulty part you put in during the rebuild or a faulty reassembly.

Third times a charm

Rebuilt the carb for the third time and no leak!!!!

 

[Matt_E]

Do you know what you did differently this time?

 

[tumblingtwerp9]

nope no idea.
I took the fuel pump apart and rebuilt it again. I have no idea what went wrong the first two times.

I have had a very similar problem before on a X-2 with a BN44. First time I left the ski in our storage build at the lake. I came back a week later and the carb and crank was full of gas. The second time was this past week, I noticed gas and oil in the hull after a ride. Once I got home and put the ski outside I looked in the hull and found pure premix right under the return line. I believe the leaky return line was fixed with a worm gear clamp instead of a zip tie. I have never figured out why my carb and cylinders filled up though.

Does anyone put a fuel cutoff on the x-2?
