I have a 1973 ski-doo tnt 400 f/a for sale. The sled is in very good condition. Just picked it up and found one cylinder to be low on compression. If you put a little pre-mix in the cylinders it will fire, but not enough compression to pull fuel from carbs. I would like to get 250.00 for this sled, but make me an offer. I also have a 79 kawasaki intuiger 440 for sale. this sled runs but needs crank seals.
