is pilot mixture screw limited on 05 wr450?

Can't seem to turn the mixture screw more than quarter turn or so. Are there limiters or does the o-ring get hard. I'm doing this with carb in place. Stan

The pilot screw will only turn in as far as its turned out. Sounds like your pilot was only a 1/4 turned out. PO jet it?

All fuel screws on all FCRs are the same as far as ability to turn. If yours is sticking', you need to find out why.

My yz has a fancy numbered clicker screw and it's real easy to tune. Maybe the wr needs one too

"Clicker" screw? On the carb? Never heard of one made for the carb, seeing as how they are spring loaded they don't need a clicker to keep the setting. I think something is wrong in there.
