My 1993 Johnson 90 hp won't idle down when you click it back into neutral. Heading in today and almost rammed the dock when I tried to throtle down to idle. Had to turn off key to stop motor. The throtle felt stiff like it was binding so I checked it out and all is well now. The motor still won't idle down though even after I take it out of gear. I don's see anything binding on the linkages or the carbs. It just won't go back to idle. When you put it in gear the throtle cable moves the black thing i'm pointing too in the pic forward and the engine rpms go up like they should. When you pull back on the throtle that black thing won't move back with the cable. Is there a return spring some where that may have brocken? Is that black thing supposed to be fixed onto the brass cable end so they move together? Thanks for any help.

This pick shows the throtle in neutral with the brass cable part back to it's place but the black plastic part is still in the open position after taking it out of wot.

Disconnect your throttle from the engine, pull on the black end peice, there should not be any back and forth motion in cable when lever in neutral.

I've done that. There is no free play in the cable. Is that black piece supposed to move on it's own or is it attatched to the cable end? Thanks

try black piece is part of the cable. the cable is probably 17 years old and time to be retired and replaced. the cables get play in them as they age.

Thanks tashasdaddy. I just didn't know if that black sleeve was supposed to be fixed to cable or not. I'm going to replace both cables today and get back out there fishing! Thanks again.
