at first i thought i had no fire on the left side of the engine.after some testing i realized i had spark.figured fuel problems.pulled the head just to check for buildup problems and everything ok.put it all back together and it wouldnt start at all.figured out that wires were on wrong.i think i fixed it still not sure.if anyone knows which wires go to which cylinder that would be great(may even be the problem???)point is now itll crank instantly and run great but now the bottom cylinders aern't "firing".in quotations because they have spark maybe just no fuel.what could possibly have gone wrong????
