Ok so here is what i got it is a johnson 115 model number j115tlarc that runs great above idle and on plane to 5500 rpm but if you shut it down to load or get the truck you have to prime it or fast idle it like a cold engine until you get it out on the water again. What i have done so far, i have replaced the themostats, both of them were gutted by previous owner, i have replaced power pack, removed soaked and rebuilt both carbs and replaced old cracked plastic bowls with new aluminum ones, i replaced all fuel lines and primer bulb, new vro, fresh plugs, and i have done the link and sync. I am about to pull my hair out and any help would be greatly appreciated. i dont know if the timing could be an issue i have checked it base timing should be 4 plus or minus 1 it is at about 2 right now. thanks
