I have a 95 S2 I just bought and cannot get it running. The guy that had before me rebuilt the carb and I have found several things amiss with it. He said it was constantly leaking from the overflow...Lol, because the drain screw was backed out, also the idle/air screw was all the way in(I backed it out 2.5 rounds from soft seat). Anyways, I can get it to start and run the starting fluid from the carb then it dies. I am assuming it is getting no fuel. I tore carb apart and found the following. 1. Main needle has clip on center ring, is this stock setting? I also found another washer (possible shim) on the needle. Remove or leave? If leave is there any special adjustment to compensate for the shim? Thanks in advance for any help guys.
