QUESTION: Paul one more thing is there points under the magneto cover?There is no spark so i took flywheel off and sanded magnet and flywheel but still no spark.I noticed that there is a cover on magneto with clip is there where the points r?

Answer
Hi Todd

yes -points are under that cover under the flywheel, make sure the points are opening and closing , if no spark  and the ground wire is not shorting anywhere ,  i would replace the points and condenser set  - make a note of wire connections , replace point and condenser , rotate crankshaft untill point is at its widest then set the point gap to 0.020 thou
tighten screw , to set timming  run the piston toward tdc  and stop when piston is 0.080 thou before tdc ( 2.03 mm )  disconnect wires at point/ condenser connection - use a multimeter set to buzzer mode and connect red lead to point wire conection and black lead to the earth loosen the 2 screws on the stator plate  and slowly rotate the stator plate untill the points  just break ( buzzer stops sounding) tighten the stator screws - fit cover plate and flywheel and timming key   tighten down flywheel nut - recheck for spark  , all going well should have spark
