question about the BX 25 throttle I can't get the darn thing to hold on the RPM that I want . every time it goes back to idle. I read the manual can't find the information. Can any help?
Tighten the nut on bottom of throttle shaft a little. You have two cup washers there that provide some pre load. Just tighten a little at a time till you get it the way you want. Just don't over tighten.
