I just finished my hei swap yesterday. Everything was fine, drove it 20 miles last night. Today ,i drove to the end of y driveway, and got out to put my trash out. I was behing my cruiser and saw a very small amount of white smoke. Then it just stalled. Now it will not start, Turns over great, and is getting fuel My question is, what do I check now,and in what order? Thanks in advance.
