i'm very unfamiliar with them.
Unless the top is removed, you can't actually measure the float level. You have to go by the way it behaves.
The floats can over time get gas logged and heavier than normal. This causes the level to be too high.
If the carb just began to misbehave, it might be a simple fix. If the carb is new to you or you don't know when it was last rebuilt, etc., it's a reasonable thing to expect to have to rebuild it.
You will also want to replace the fuel filter located at the fuel inlet/filter housing (1" size wrench to remove it). Hold the 1" from turning while you turn the fuel line fitting off w/a 5/8" fitting wrench (if it still has the OEM steel fuel line)- then remove the filter housing.
Be careful of the plastic gasket on the end of the housing- don't let it get between the threads when you reassemble it, and be careful not to overtighten or cross thread it.
