I have a 5 year old Simplicity with a 22hp Briggs V-twin (model 44K777). At 2 years old I developed a low speed miss that progressed to higher rpm. Eventually found the right bank coil wire arking, so I replaced the coil pack. A year later, another miss, coming from the left bank. Replaced that coil and all was good. Here I am 18 months later and have developed, again, a lower speed miss (which will progress). Replacement coils to date were OEM. I have no idea why these packs are going bad, if I should be looking for a root cause or if there is a better replacement. Ideas, help?

Hi everyone. I have a Porter Cable generator model BS1550 (Briggs & Stratton engine). I need some help in attaching an auxiliary fuel tank. I want to stay away from a gravity system. Any help is appreciated. Thanks
