I recently rebuilt my 97 waveventure 760 engine with new cylinder sleeves, carbs, intake, pistons, etc. Last weekend I went to go and start up my ski and there was what looked like a bunch of oil and gas that was sitting in the intake manifold under my carbs. Does anyone know what could have caused this to happen? Also I found a broken feed back for my carb that I had repressed into the block don't know if this could have caused the issue or not.
