its all personal preforance... there are a ton of good oils, the only thing is they are all made in the same factories and have a few "secret" additive once they are purchased added to them.
Very common oils are Yamalube 2R, Maxima 927, Motul
most ppl run them from 32:1 to 40:1 but its all personal preferance... you will get alot of differant answers
with 150 psi you can run pump gas... but if you plan on running any timing advance id bump to 50/50
edit: also unless your running at like 500 feet below sea level your jetting seems very rich... have you done a plug check?
