There is one down side over the VM 26 carbs is that direct hot starting can be a problem, Most cases they will start up if you turn up the idle screw half a turn, if not you need to just catch them on the throttle when you kick it over, it’s a different technique depending on your state of tune and set up.

Carb may flood on first installation or after the float bowl, this is it settling in, just turn off the fuel and run the engine then switch back on the fuel.

Please note for the 125 and 140 engines the lowest idle RPM will be around 2700 due to the style of slide
