While you're checking, check the HS bypass pressure set it too to 60 lbs. I'm not a fan of useing a pill in the HS, but i know it's a Kinsler setup that does this. Most nozzles like 60/65 lbs pressure to dispurse the fuel properly. Hilborn flows theirs at 65 lbs. when they rate the flow. Too be honest with you the nozzles are pretty small for alcohol, they're border line between gas and alcohol. I realize that the injection is only 2 1/16", example we run 18AS with 2 3/8 and 2 7/16" injection a friend run a 350 sprint car and 2 3/16" and runs 18 AS nozzles. Below is a chart for cross ref. of Kinsler, Hilborn, and Enderle nozzles. Yours cross over to a 12AS Hilborn, this might be a problem, if you have any available try a larger nozzle. It takes lots of alcohol on the bottom end under load, and then the HS leanout takes over, we also run -1/2 pumps.
