My son and I just converted an 87 GXL to a TII. Complete swap, drivetrain, the works. We have had it started a few times but it won't stay running. Now, it won't start at all. Pulled the spark plugs (new) and they all fire. But, I noticed the top 2 were soaked with gas while the bottom 2 were as dry as the Sahara. Does this make sense or is there something else we need to look at??
