Does anyone know why you have to drill the slide lift on the 97 400 kit? I was thinking about getting the kit, but was uneasy about the thought of drilling something, especially in the carb. Is is a very critical job or, just drill it out?

it's a very easy job the drilling is not technical just a small hole
What does the drilling do? Does it give good results? Like, actually do what it says? Sorry for all the questions, just want to make sure I do my homework. Thanks.
Well got the jet kit installed with no problems... but I had to bring the idle mixture screw back to 3 turns out. The kit listed 2.5 turns. Also they sent me the wrong precharger for my K&N.
When I turned the idle jet back out to 3 turns it seemed to be running better and it didn't smell hot anymore. I did end up pinching the choke plunger's plastic seal when I was reinstalling it. Would that maybe cause it to be running a bit rough? It is surging a bit and sometimes stalls.
