Need help locating an Air Jet for Yamaha carb

[76Red18]

As long as the hole in the jet is not disturbed you can file the rest of the broken head off and carefully cut a new slot for the screw driver. The diameter of the jet's hole is all that matters. I have 2 of 6 like that in my 150 Johnson. Not sure of the thread size of your jet but go to a hardware store and find a nut with the same threads, wrap a tiny bit of black electric tape on the jet thread and screw it into the nut. You can then hold the nut with pliers or a vice while filing the jet.
