SOURCE: 93 honda cr 125 r has no power

i bet it is the float needle check to see if it has dropped down to the last notch. i think there are three they regulate the amount of gas that goes to the engine its in the carb and easy to check.just unscrew the top piece and its right there.

turning the screw way out makes the mixture lean, so the problem must be the carb is too rich.
check all the jets were installed correctly when the carb was cleaned
make sure the carb float bowl is not flooding.
Check the fuel tap is working correctly.
make certain the airfilter is clean.
check the engine has correct amount of clean oil( not fuel contaminated)
