My 1975 Johnson 25RL75B dies anytime I throttle it down to low throttle to shift. I'm thinking my links and everything may not be set right. Any suggestions on what to check? Anyone have a manual or can tell me how to adjust all the links and whatnot? I really don't like shifting it without going to low throttle. I have adjusted the low speed to the best of my knowledge on how to do that. Sorry if this is confusing. I'm typing while watching football.
