Yamaha F100AET Carburetors

[dannysib]

Hi All,

Wonder if you can help, completely at my wit's end here.
I've got a fairly low engine hour Yamaha F100 AET 4-stroke outboard which is running like a bag of spanners!
I've rebuilt the carbs and Sonic cleaned them to no avail.
It seems Yamaha has stopped supplying the carbs for it.

My question is, does anyone know if any other carbs fit that model of engine?
The Carb Numbers are:
67f-14901-20
67f-14902-20
​​​​​​​67f-14903-20
​​​​​​​67f-14904-20

Thanks in advance!

Dan

Replacing the carbs is not the solution!

A few questions:
Did you completely disassemble the carbs including removing the emulsion tubes?
Did you blow thru every orifice with high pressure air?
Did you use gauges to balance the carbs, with the throttle linkage disconnected?

Just because it didn't work the first time, or the second time, and possibly the third time doesn't mean you can't eventually fix it.
