Float level is logically possible,.. but not likely...
The main jet, is clogged, or the slide is sticking...

To be the float,.. it would have to be at exactly the level that would allow idle but run out instantly upon opening the throttle...

When adjusting the float,... forget millimeters and micrometers,... just adjust it so that the float arm is basically horizontal when the valve closes...
(hold the carb horizontal, and blow in the fuel inlet,... raise the float with your finger and it should stop passing air at horizontal)...
Low tech... easy peasy... ...

Good morning!!!!
Well I adjusted the carb float by youre method and she started right up and I let her get warm and started to roll the throttle and noticed the pipe getting hot so I shut her down.
I had just changed oil and filter and was afraid I got the filter in backwards , but it was in right. the oil in the crank case is cold.
This bike has been set up for two years, could there be a reason for her not oiling ; and is there a sure way I can verify that she is oiling?????
