I bought a 40 S a few weeks ago and have been fixing all it's problems, and there are many as the PO didn't believe in fixing anything if a patch would do. Anyway, it runs poorly. It is strong but won't idle worth a crap, I've cleaned and gapped the plugs and cleaned and set the points and have done a fairly decient job of cleaning the carb, mainly cause I didn't find anything wrong. The carb to manifold casket was bad so I replaced it and none of this helped much. It does idle a bit better but still not even close to what it should. I've also noticed that when sitting there running it will condense water on the outside of the carb and on the bottom part of the manifold. What is causing this and what is the cure? I'm fixing this tractor to keep as I've always been partial to the M/40/420/430 series and want to have this one here to use plus I may take it to some local shows and such. Thanks, Nat
