I have a 1986 B2000 and found the vacuum delete on YouTube and have to say thank you for the input. I'm in Tennessee and don't have any emissions so it is fine. I started my truck today after doing the head gasket. Finally got it started and went to run it around the block and the radiator cracked at the neck. Go figure lol. But would love to provide video and/or pictures to show the progress. The only question I have would be what kind of Webber carb should I buy to replace the stock carb eventually. It also seems like I have a little less power why would that be?
