whats going on. i just receantly refreshed a ka24de out of a 93 240sx. i replaced the head and all of the timing components. pretty much went to start it yesterday for the first time and it started right up and then died. i started toying with the dizzy to try and advance as well as retard the timing on it. of course after running and then putting until it died it flooded the engine. so i finally get it started again and the revs junped all the way up around 4 k so i got my buddy to retard it a lil bit and then it died again. i cant seem to figure it out. it was doing some back firing the second time around so i immediatly checked the cam gears to make sure all my marks were right for timing, which is second mark on the crank pulley and the first lobe of both cams facing outward of each other . isnt this correct? its def getting fuel and spark, im lost. anyone got any ideas?
