Talk about Lazy...!
I'm jetted for 60 degree weather 152/42 RB'ed
and the weather outside is 40's all week
Can I go to 42:1 from 50:1 to richen things up?
Have you ever heard of such an idea?
Changing Fuel / Oil ratio instead of Jet's !?

Figure out the volume of fuel difference between 42/50:1 and you get a very little number. Hard to compare to what the volume of delivery is with a different sized hole in your jet..but doubtfully as much. There's a thread here about that...but I'm too lazy to go looking for it.
Yes, it changes the air/fuel ratio, but not as much as a jetting change will/does.
If the main is what you're changing with temp changes (probably), access it through the access cover on the bottom of the bowl. No need to take anything apart.
That said I generally do change pilots as seasons come and go. ...need a bigger access cover for that!

Bear in mind that not only ll the ratio affect the jetting but that the oil you use to make that change will also affect it by the oil's viscosity. A Thicker oil will slow down the to volume of mix flowing through a fixed jet size. Instead of adding more 2 stroke oil, , keep that ratio constant and add 80 wt gear oil to thicken up the fuel and there-by lean out the "Jetting. ".
Let me know if it works

Which cSt rating @ 40ºC of SAE J306 rated viscosity oil would you suggest?
Yes. I am glad I could help.
