just got a 79 kawasaki 440 and have done a little work(fuel lines and such), but no matter what i do it wont start. it turns over just fine and i can hear it wanting to start. it is getting spark and i know the fuel is good i am pretty sure i replaced the hoses correctly. does anybody have a good check list or trouble shooting list i can go off of. i am about to start taking it apart piece by piece and seeing what i can see. any help would be awesome.
