I got the old sled running but i'm wondering if i should be mixing the gas 40:1 or 20:1 like they used to. I mixed 40:1 for now, 125ml of oil to 5litres of gas but you can't barely see a tinge in colour and back when I was a kid I had one and I remember the gas being blue from the mixer. Anyone got any suggestions

if i remember corectly the old skidoos were suposed to be run at 50:1 depending on the temperatures being run at so if ure running 40:1 than you should be fine, the way i usually figure them out specially that old as long as you can smell or see it in the exhaust than its fine.
