RE: DL-50 engine
sorry i do not have a digital camera yet .but i will try to clarify.the adjustment screws on the carb stick out right.slide a straw over them.now try to put a screwdriver down the straw you will be on the screw evry time . all you have to do is glue the straws side by side and they cover both adjustment screws put them through a hole in the side of the cowling with a small flange (i use light ply)to screw the straw assembly to the cowling .thats it it is pretty cool even will hold your screwdriver when you take your hands off .
