After warm up, about 5 minutes at full throttle the engine bogs right down to trolling speed. I pulled and cleaned carbs right out, replaced fuel lines, primer bulb and checked fuel pump. After noticing a few chunks of rubber in bottom float bowl, probably from old fuel hoses. After doing all of this we noticed that it bogs after warming up and after sitting for an hour it runs fine for another 2-3 minutes. I'm thinking an ignition part is breaking down from the heat. I'm just wondering if there is a comon issue with these before I start throwing parts at it. Any help would be great, thanks for reading. |
