Echo CS 302 . The oil nipple is located under the cap on top next to the body middle. ItÆs near impossible to get to. The replacement part I ordered here was the Same size as outside of connector, so it would not fit. I simply bought a piece of 3/16ö clear gas line and use curved Hemostats to insert the line OVER the entire connector. Thi s works fine and the oil filter has a nipple on the end and will work on this hose. It was hard to get to, so be patient, go slow and youÆll get it done. In the end, use need,e nose pliers to finish pushing hose on. It will go only about 3/8ö - 1/2\" until it reaches the end. Friction fit is all. I thought at first my cam was worn on the crank which operates the oil pump plunger. I was wrong. I removed the oil pump, put a pencil in, pulled the crank. The pencil jumped up and down showing me the cam lobe was OK
TEST THIS FIRST,,, And save you a Lot of grief ! Look inside the oil tank also for the hose and if itÆs connected. It dissolved, clean oil tank with Gumout carb cleaner. Working like new !!
