Hi Troy! The black plastic check valve is fit slugly. It can be turned side to side but is tight and not loose. The plastic clip is istalled so it does not move when the engine is running. I changes all the fuel lines including the one inside the tank. Will try it out tomorrow. Can I take the plastic check valve out and use the check valve for th pressurized S airplane or helicopter engines instead until the correct check valve I ordered arrives or is it better to run it without a check valve for the meantime? Also, my carb seems to be spitting out some fuel since the top rubber portion of the soft mount and the rear of the beams get wet with oil while the top and front part of the engine as well as all the fuel lines are bone dry. What should I do about this if anything? Thanks.
