Tillotson HD carb in my 75 ski doo.  I go through the carb, clean it, make sure the needle is free. Boom, sled starts and runs fine for about 1-2 minutes then dies and won't restart.  Find out the needle is stuck again.  What do I need to do to make this a reliable carb.  New needle and seat?  If so can those still be purchased?

Yes you can get parts for them yet. Try Dennis Kirk or Shade Tree. A dealer could probably get them through outlets like Parts Unlimited too. Those carbs weren't very reliable when they were new. Make sure the tank is clean, put on new fuel lines, use fresh gas, and possibly an extra filter. These carbs are very sensitive to things like gum, varnish, dirt, or any other fuel related problems.
Good Luck in your repair.

Also be very careful with the gaskets & diaphragms. If you get them out of order or flipped over, that will mess things up too.

I got rid of that carb, I put a Mikuni slide carb on there, seems to be running great so far, winter will tell more.

I have a 69 Olympic and I keep having the same problem with my tollotson HR.
Can you get those grosse jets for them?
I must have cleaned the needle and seat 100 hundred times last year!!

HI i have a tip that i use in my old sleds that have sat over the summer and the tillotson carbs get all stuck up. What i do is take the filters out and get rite down to the needel valve and i take it out put a bit of oil in hte hole it came out of and soak the needel valve in oil then put it back together puting a bit of extra oil on teh valve and when u put it on spray some gas in the carb and it sould start and stay running. WORKS GREAt especially after they have sat over the summer if u dont want to buy a new carb kit.
