I have an Mikuni HRS42. the enrichener will not stay in the engaged position. I just pops back to closed when I pull the knob and let go.

I read where there is some kind of detente to keep it out. Where is it? Is there some kind of adjustment?

behind the knob is an adjustment screw, loosen the large bolt behind the tab it's attached to and adjust the cable so it won't pop back in.

On the newer mik's there is a small-round-plastic-doohickey right on the enrichener knob it's self, it's part of the cable. You can just turn it righty-tighty, lefty-loosey in order to stiffen or loosen the pull or push of the knob it's self. Hope this helps.

Sometimes the plastic screw in the back cracks so it will no longer stay tight. If that is the case, you will have to replace it.

Good luck.
