Question about 1996 Honda XR 600 R
I adjusted the valves, correctly I hope, finally got it started. Adjusted the idle up to keep it running but now gas is pouring out of the overflow tube from the carb. What did I mess up?
Presuming that the carb is clean !
It seems that you have either set the float level incorrectly, or allowed the needle to become jammed. The float bowl should a little less than 3/4 full of fuel when the fuel is shut off by the needle and seat.
Check that the needle and seat are working correctly by blowing in the fuel pipe, and then closing the needle by hand. Check that the flow is stopped when the needle is fully raised.
The needle and seat do need to replaced from time to time, but generally last well.
If the needle and seat work, then look at the float level.
Further check to see that the floats are not filling with fuel. If this is the case, then the floats will have to be replaced as most repairs are only temporary.
When the floats are fuel logged the needle will not be raised and fuel flow to the carb will be continuous.
