as far as oil mix, i followed joes advice...24:1 for the first 3 tanks then 32:1 after that...16:1 is too thick and will eventually result in fouling your plug and or killing your engine due to carbon build up
id like to say something on gas octanes here: i run 93 octane at 32:1 with valvoline synthetic multipurpose 2 smoke oil. I also have run 103 octane at 32:1 oil mix and the difference is extremely noticeable... the higher the octane the cleaner the burn...clean burn equals better combustion which in turn DOES make a difference...ive also been stuck using 87 octane and had to change a top end shortly after doing that...
i prefer to use mobil 93 octane gas...seems to be less crap in the gas and has continued to be of great burn for my china girl...
this is just my opinion...
