Ivan kit and revisit to cold starting

[Falcon 269]

The measuring technique, ie with the end of a vernier gauge, is fine.  It's the illustration that's misleading as it suggests you can do this with the carbs horizontal.  To get the float to rest on the valve without depressing the spring-loaded pin requires the carbs to be tilted. 

Rotate the carb bank so that the floats fall away completely from the valve, then slowly turn the carbs back until the float tangs just touch the pin.  Go a few degrees further and you'll see the pin compress.  Now, turn the carbs back the other way until just touching again and that's where you take the measurement.  Takes a bit of practice so do this several times before making any adjustment to the float tang.

It only takes a very slight change in the angle of the float tang to achieve 14mm float height.  About 0.5mm deflection or very close.  If you have to bend the tang more than that, it's a good bet that you're not measuring with the float in the correct position.

The steel tang is quite springy which makes it tricky to get the correct amount of bend because the tang deflects back again.  Often it works out easier to over-bend the tang and then ease it back up to where you want it.
