hi, i recently dropped the gearcase on the 75' 25hp johnson to check water pump. All is well and i got put back together just fine. Started her up in a barrel of water and there was a good spray coming out of exhaust ports. BUT, when idiling it felt like it wanted to jump into gear. a catching sound, then a stall. figured it is the linking on the shifting rod that needs to be adjusted. Is there a method to figuring out which way to adjust it, up or down. <br />thanks a bunch.
