What model is this?

[Bernoff]

Going to take some polishing to get mine to look like that.

Oopsy Daisy!!! Didn't realize filter was held on by a little screw. What have you guys done to fix or found parts? Local dealer tried but said he has no one that he knows to contact.

TheY have done some wotk on my uncles sled.
They will likely know who to call if they don't have it.

Is there anything a guy can do to recondition a really old belt so it does't blow up?

The oil to gas ratio is 20-1. How much lower ratio can a guy go before you start running into fouled plugs and hard starting. Want to give it a bit more just to help it along. Thanks.

Here is my take on it. I bought a new T'NT 440 in 1972. Recommended gas - oil ratio was 20:1 just like your sled. The next year Skidoo came out with better quality oil to be mixed at 40:1. The dealer which was Turple Bros. in Red Deer told me it was okay to use it so I did. I had no issue with running at that ratio. The benefit was way less spark plug fouling. I could actually have a few rides without changing plugs. Later on in it's life I switched to running at 50:1 ratio as oil continued to improve and had no issues with that ratio either. I think I had about 7000 miles on it when I eventually sold it after 20 years. A big trip was 50 miles in those days.:d If you think about it if you put more oil in the fuel you actually decrease the amount of gas in a given amount of fuel so you are running a little leaner because of it - not that it matters a whole bunch. Bottom line is that today's quality 2 stroke oil has way better lubricating properties than that of 50 years ago. I certainly wouldn't put more oil in the gas.

'72 would have been leaded gas....probably $.25 a gal.

 

[retiredpop]

Leaded for sure. I ran premium for the most part. I think it was about $11 or $12 per 45 gallon drum.

Was walking through Canadian Tire the other day and there it was. Kimpex filter to boot. Working on getting the skies to point it the same direction now.

WOW...…!!

When I was in high school, I remember buying farm fuel from my dad for my old truck.... $0.25/L … thought that I was getting a smoking deal... until I realized that the old chevy got about 5 miles per gal

Those were the days..!!

We had a 1969 Nordic 399 (one year older than Bernoff's). I used to walk with a 5 gallon metal pail (empty oil Pail with lid) to the Esso bulk dealer in Leduc by the tracks. I would buy a quart of oil and put that into the can and then have the balance filled with dyed regular fuel. I can't remember the price of the oil but the gas was 20 cents per gallon. I think it was about $1.75 total (under $2.00 for sure) and I would lug this back to our house (we lived just east of the bulk station) and pour most of that in. It was only a five gallon tank so sometimes some was left over and I would add that later. I was 12 years old and man I had fun with that sled.

 

[Bernoff]

Sometimes the pail was to full and missed the funnel. Lol. Would have to dig a bit of a runway to get unstuck. Tough as nails back then.

 

[darrell]

it is a 1970 Nordic you should check out Davids vintage snowmobile site he has all of the snowmobile ever built on there
