Hi Anyone, Please Help. I have a 1980 140Hp Johnson engine that starts great, idles and revs fine, and will will run at low speeds. When you go to accellerate it will run for 50 meters or so then bog down and stall. It will start again and idle but when you go to take off again it will bog down. I had it in to a shop and they removed and replaced the carb kits and adjusted the air and fule screws. They tried it at higher RPM and trolling speed but can't fully test at High RPM. I picked the boat up from the shop dropped it in the water. It started great, idled fine but again bogged down. Any suggestions?
