93 skidoo formula mach 1

Hey guys what's up just picked this sled up cheap she rips however I was told its a 93 skidoo mach 1 670 bored to a 715 its a twin .my question is the oil tank pump has the block off kit so I gotta premix the gas an oil in my 5 gallon can then dump into sled. However does anyone no how much oil per gallon of gas? I don't want to blow it up she runs awesome. An what kind of oil should I run? I'm an ATV guy but for 200 bucks I wasn't going to pass it up. Any help be appreciated thanxs steve

Start rich like 20:1 and maybe lean from there by checking your plugs
Always go rich cause plugs are $2 and engines are $2000

Run 40:1. 20:1 will foul plugs all day. Any quality 2 stroke oil is fine.
