With your set up and stock carb--it actually looks lean...
..does it idle good or do you need to kick it higher?
you should be able to run .098 at all 4 corners.. and still not be rich...

_if your plug looks pretty white....you are too lean on the jets....a nice darkish brown--and even slight black around the ring of plug--and still not be too rich...if this takes a high idle--then increase primary jet to .100 or 101...and secondary to .098...

pull a plug before putting on the top...

I take the top off between races to change jets if necessary...
