I have a 300 Honda I don know the year of it iam guessing 96/97 ,, sometimes it will fire and sometimes it won’t when it does start up it will continue to start as often as you won’t to start it,, but sometimes just no fire at all I put a new CDI box on it and it did not fire at all put the old one back on and it started up ran good until the next time I tryed to start it ,, I charg the battery and it started but now it’s back to fireing sometimes again… Any help or advice or help thanks in advance..
