My 08 TXC250 has a slow & pretty much constant drip out the bottom hose on the CARB AFTER I have killed the engine and the bike is put to rest for the day ... I have tried cutting the fuel off at the pit cock but the el cheapo twist \ screw in pitcock will not seal off 100% ... Is this the float level in my CARB causing this leak? And if so, how do I adjust the float level on these CARBS?
It most likely piece of dirt hung up in the needle / seat. Pull it apart it may be worn and not sealing properly.. Chow, Carl
These CARBS are a pain to get off ... But I do have the time avail There was a little dirt around the valve ...but I don't think that was the problem ... I cleaned it and it still dripped ... I'm trying to ADJ the float level by bending the metal piece that the shutoff needle hangs on ... After the floats, I don't see any other way it can leak unless the O-ring on the base entry point on the fuel has gone bad and is not sealing anymore ... It looks OK, no cracks or anything but it does look a thin on the outside ....
Fixed! It was the 0-ring around the valve seat! No 0-ring here but I did have a JDjetting CARB kit so I used the smaller of the 2 0-rings in the kit ... It was too small but no leaks yet! Slow leaks, drips? Check the valve seat 0-ring.... Gas pouring out? Check the needle valve and valve seat for dirt or excessive wear... Last, change the float level if necessary ...
