Zenith Float Level

The Zenith float level guage tool is very difficult to find. Here is how to set the float level without the guage.
You will need a screwdriver, calipers and a bit of patience.
Remove top, remove pump from top, replace top on carb. Pull distributor wire, so engine doesn't start, and turn over engine till carb is full. Remove top again and measure with the calipers the distance from the top of the carb body to the point when the caliper end touches the fuel.
This measurement should be 18.5-19.5mm.
To adjust, use shims under the needle valve. Just remember there is a 4:1 ratio, 0.25mm shim will lower fuel by 1mm.
When you get the correct level, put back together and you're ready to go.
