I pulled the bottom carb. but still can not see how too disconnect the linkage, the only screw I see is turned around backwards an screws out towards the power head,is there something I am not seeing.I have done a water pump in the past(about 15 years ago )an that 1 had a cotter pin you pulled out.Yes I know i need too get a book but money is real tight right now, just got back too work a little while back. Thanks for any help
