It is my understanding that there is a difference between the MKI and MKII on the difference in the diameter of the hole in the slides. I read in another post about using a dinajet kit and it said with the weaker springs, the slide hole needed to be opened up and frankly, that did not make sense to me. I would have thought that weaker springs would require a smaller slide hole as a larger allows more vacuum to pull the slides open quicker as would weaker springs.
What would opening up the hole do on the slide actuation, especially with the washer change and extending the needle out .030 more on an 83 model?
