I have a 1993 350L 4x4, this is a new to me machine. When I got it there was fuel leaking out the carburetor, so I bought a rebuild kit. I soaked the carb in parts cleaner for a couple days, rinsed it in water, and blew it out with air. Put the carb back together setting the float lever level, and now it only drips when running. Again I took the carb out, and set the float lever up a little from level, and still a drip, but only when running. Again, I pulled the carb, and set it a little more , and you guessed it drip.
I am guessing it is the needle valve, but it is brand new, I purchased one of the Moose rebuild kits.
I am thinking about just going to get another needle valve, but I am wondering, since the OEM set is $48, and the after market is $12, is this one of those time where you get what you pay for, and are the aftermarket needle valve sets known to be junk?


Thanks for your help.

sorry for resurrecting an old thread, but this is where I am,

1993 Polaris 350L 4x4

I have a carburetor that is giving me complete fits trying to figure it out.

To start with it has a fresh cylinder bore and new piston. PSI is approx. 135. This is also what I have done so far:
• Complete re-build kit
• Complete cab clean
• Replaced the needle jet assembly not included in the re-build kit
• Replaced float arm pin
• Replaced float arm
• Submerged floats under water over night to make sure that they are not cracked and taking in fluid.
• Filled the bowl with gas while it was removed to make sure the internal overflow tube does not have a crack. Also put my finger on the tube in the bowl, and blew into the hose to give it a little pressure, and there was no air bugbbles.
• Replaced reed valves
• Set the float arm to level with gasket surface and then again just a little up from level from the gasket surface.

No matter what I do I have gas dripping out of the drain hose from the bottom of the carb. I even went to the point of setting the float arm to where it does not allow gas into the carburetor, and backed it off from there. I must have taken the carb out of the machine and apart 100 times making fine little adjustments to the float lever, no matter what I do it drips.

Last fall I took it into a local repair shop, after he worked on it for a few days he gave up, and gave me back my machine. This sat in the corner of the garage until about a week ago when I decided to try and figure it out for myself…any help would be greatly appreciated
