I have a 91 L's I pulled the b18a1 and went with b20b low comp from 96-97 CRV won't stay running and puffs white smoke from intake. I know there are a lot of forums on b20 swaps but my question is if I use the b20 distributor wired in it will start and run for about one minute while wanting to die out the whole time before it finally does. If I use stock Ls dizzy it gets spark but won't crank at all. Any suggestions???
