idle set screw

[stevespears]

the top of my idle set screw broke off and the spring is lost. i looked online for a replacement, and found a part called the idle stop screw. is this the same thing?

2 stroke 50tlr outboard idle

we can't get this motor to idle properly. harder start, in neutral it doesn't stay running, when you accelerate it boggs down, and once you put it into gear, it almost always dies.

we have changed gas , plugs, and the carbs look clean. when we spray carb cleaner in the carbs, the rpm goes up and back to normal, but all of thats done in neutral at almost WOT

AAAAAAAAAHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!

Sounds like you need to pull and clean carbs properly and do the link and sync like the Yamaha service manual says

Why would you turn the screw so hard that it breaks off?

It is always best to make sure compression is good on all cylinders first, and then spark and timing.
If all of that is good then work on the fuel related parts

My money is on a broken fuel delivery system. Still need to take off carbs.
