well id have to start somewhere.i replaced the plugs and it has spark.i had someone do the tming for me,and we did it about 6-7 times it sounds diff everytime like it could be off or something but when it was timed "correctly" which it probably was,i could start it but id have ot keep my foot on the gas about 1/4 throttle if not more to keep it running and it sounded way out of time or a mis-fire or something like that.
