I'm running a 92 faststrike 150. Motor has always run great but here lately the last 2 trips it acts up just sometimes when ever I first start it. It will act like it's running out of gas or something. I'll start givn it throttle and it will die. I restart it 2 or 3 more times and it'll clear out and run great. Anyone ever experience somthng like this? Also, it has some champion spark plugs in it right now, i've never been a fan of champion plugs. Do I need to use a specific spark plug or can I just cross reference some NGK's. Thanks for any help.
