Ok guys...so...troubleshooting the infamous Mercruiser 120 hesitation. I have been living with it for a few years and it remained after my last carburetor rebuild a couple of years ago. I battled it for a year or two then just decided to give up and live with it. I am thinking about beginning the battle again and in my research, I discovered a dimensional inconsistency between the Mercruiser manual and the instructions in the kit. Please take a look at these two links:

Link 2:

Go to page 25 of link 2.
While the float drop and float level measurements are the same, the measurement point is obviously quite different.
I set my boat up to the Mercruiser Manual which is link 2 and the bog remained but the rebuild kit I purchased contained the same instructions as link 1. So, which is correct?
I also know that I need to check my ignition timing as well as dwell. Those inspections are in the works but I thought I would get some opinions anyways.
