if you think it is the autolube fault, it is not a question to set it up correctly or not. The autolube is either working or not.
It happens that the autolube gear breaks and or the autoluble three get damnaged, and you you don’t have any oil in your mix.
To check this just open the clutch cover and check the condition of the autolube gear and its connected three. If it is broken and you want convert to manual mix, you can take the parts out. (but not the gear washer that is between the cranckshaft and the clutch since it has also the function of a spacer for the correct use of the clutch.
For you carb set up try you didn’t mention the exhaust you are using, and if your cases are ported and if you use a racing cranckshaft. So considering all this variable the main jet could go from 122 to 130. If you will tell me more about your set up I will try to be more prcise (or some other in this forum).
The spark grade you should use is on Bosch scale 3, Denso 27,
Timing 17 - 18 (considering wich exhaust are you using).
