I have a Tecumseh engine 13.5 h.p. OV358EA, engine. I need to know the size of the bolts that connect to the dip stick 1?. 2 one is at the back where the spark plug is at? and the 3 one is on the other side from the dip stick? when the shroud is all connected to the baffle I believe it should be tight. its loose and I am afraid that the baffle will hit the electric starter if any one can show me the right Diagram for this engine it would be of great help. if you need pictures, I think I can take some, let me know what info you will need.
