I think yours is the model with the circular float bowl. So check:
Solenoid is OK probably is.
Float floats probably does.
Float needle seals probably does.
The O ring on the vertical fuel spiggot is probably not in the correct position.
If the float bowl has been taken off trying to get this O ring into the correct position is
very difficult. You need to take the carby off to ensure correct assembly.
Also always turn the fuel off.
the standard valve clearance for kawasaki barako is 0.08mm for intake and 0.10 for exhaust
The correct valve clearance for kawasaki 175 is 0.06mm for intake and for the exhaust is 0.08mm
for barako 175 for me much better is 0.03 for intake and for exhaust is 0.07
