I purchased a used 76 johnson 15 horse a week ago and watched it run in a barrel before buying. strapped it onto my 14 foot boat and it starts and idles great, but thats it. I try to crank throttle and it does not increase speed or rpms. I took to a boat shop this mourning and he said the teeth in tiller handle are lined up properly, and all functions of throttle are working correctly. After leaving i replaced the spark plugs, and looked at choke carefully to make sure it was fully disengaged. I just got off the water and its doing the same thing. Will not rev up. I can only go at a fast idle at best. Is this a carb issue?
