first mark your bottom pulley where the 0 is,with no plugs in the engine stick your finger into to #1 spark plug hole have your helper tap the starter till you feel the piston blow you finger out of the hole,look at the front pulley it should be close to 0 if not put a wrench on the bottom bolt and bring the engine to 0,next insert your dist so the rotor is pointing to the #1 wire on the cap,this will take some fussing you may have to remove the dist shaft gear several times to get it all pointing in the right direction. the pic of your your engine looks like its ready to go so maybe the builder already did all this for you, anyways thats the easy way to do it then just fire it up.
