Float Bowl service check and adjustment guide
Posted: 05:38 am Jan 08 2014
Hi All,
Checked the float service hight and adjusted after as per the manual - some pics FYI if anybody ever needs it. (Please feel free to correct!!)
1: Create Level reading pipe- essentially a see through pipe with some sort of cork that can be fitted to the carb drain plug.
2: Attach the see through tube to the side of the carb - connect fuel hose, and get carb perfectly level. Open tap, and observe the fuel rising in the tube until the float valve seals. The fuel should settle at the carb bowl / carb meeting line, or up to 2 MM above that point (Hard to see on the photo - fuel line next to my finger, fuel level probably 4mm to high. (Note, Camera angle wrong here, carb is level).
3: Take open carb and measure float hight. Angle the carb against an object so that the float tab just touches the top of the float fuel shut off without compressing it.
Measure from top of float to carb bowl / carb meeting line. Should be 16mm + - 2. (To get my fuel level to settle as per step 2 I have to adjust my float to 20mm... )
4: If required, adjust tab on float, and repeat 2 until happy.
