What does the guide say? Read it again.

OP you are over- jetted - Center carb jets at 62 or lower.
180 is the wrong thermostat temperature. 195! Pay attention! Stop wasting everyone's time with the 180 operating temp- it will not run properly at that min operating temp- it's in the guide!!!. 195 thermostat - at this pt just buy one from Napa, or look on line for a oem nos 195 temp
the temp change alone to 195 will affect how it runs.............
Float levels
initial timing 16-18 btdc
coolant mix
Firecore spark plug wires
plug gap 0.040
please read the guide

I know about the t-stat it’s on my list of to do things. I’ll probably just get a Murray from Oreilys.

I’m going by the document. Maybe I wasn’t clear enough. It WILL NOT stay running at 1/8, 1/4 or even 1/2 turn out on outboards regardless as to what the guide says it DOES NOT work here and I seriously doubt going up 15 degrees in temp will change that but we’ll see. It wants at least 1 turn out to keep running. Now if it had a 160 and I was going to 195 that would be significant.

What about the Autolite 66s in combo with 195 t-stat is that likely to lead to running too lean? Is the 66 ok to use?
