Fuel/oil mixture ratio

[Canadian_bacon]

Hey all,

i just rebuilt my sons '89 Polaris long track 440 engine. The oil pump has been removed so I didn't install another one. Just wondering on what a good fuel/oil mixture is for the first tank of fuel though it. I'm thinking 32:1 should be good but wondering if that's too lean for the initial run. Any other opinions? Thanks.

thanks All, I found in the manual that for premix engines, the first rank of fuel is 20:1 and after break in the ratio is 40:1. I know this machine was originally oil injected but I think I'll use these ratios. Thanks for all the replays.

I would add a little more for the first tank or two. I can't remember what we used to do but for general running I thought we used 32:1. I might be out to lunch but it was many years ago.

old ski-doos were 50:1, so 32:1 for first tank is more than enough oil in my opinion

Here's a link. Google has lots of this reading.

Spray generous amount of oil down spark plug holes, then if you can into the throttle bodies. Fire it up with 32:1 mixture in the tank, and drove it like you stole it

Buy 2-25 litre gas cans and add 500ml (half litre) of 2 stroke snowmobile oil for each one is the most easy way to do it

Pretty sure that's what I did for the first 2 tanks of break in on the axys. Says to do so right in the manual.
