Fuel Screw replacement 2007 WR450
Posted March 31, 2013 - 05:10 PM
The question is, if I unscrew the fuel screw, will the spring and stuff stay on the fuel screw? or will it end up in the float bowl? I have never removed a fuel screw before so I'm not sure what will happen. If the spring will stay on, I believe I can replace it without removing the carb.

The fuel screw sits outside the float bowl. No need to remove anything.
Do not use the old oring if you replace it; get a new one.
Do not use a aluminum fuel screw. The corrode and break.
Do not use a tapered tip fuel screw. They are impossible to tune.
+1 on the aluminum PO did that to me PITA to remove cleanly.

"Hi, quick question. I don't want to go through removing the back end to get to the carb to replace the fuel screw with an after market one. The last time I had the carb out I removed the fuel screw plug"
If your carburetor is the same as a 2011 WR 450 you can not get the fuel screw out just by removing the plug. The hole is still too small for the threads to go through it and you will need to also drill it out to a larger size.
