Hi, I purchased an old (1972) Toro 726 today. Unfortunately, it will only run on full choke for a minute or so then stall. Can anyone help me with the carb settings for this thing?  I picked it up thinking it only needed to have the carb cleaned. I've since changed the head gasket, spark plug, fuel line, fuel filter (clear, inline, paper  element, arrow is supposed to point in direction of flow right?). I've found that when she begins to stall if I choke it with my hand over carb she will suck some more fuel and run for awhile longer. The fuel filter does seem to be running low on fuel and after starting it I can even see bubbles in the fuel filter. Any advice will be much appreciated. Thank you,

You have a 185? Nice tractor! A hyrdo is just fantastic to operate. I wish mine had one!!!

You could very well have more crud in the carb, or even the fuel tank. Those metal tanks are known to rust, so you might be getting rust flaking off & getting into the carb. Both should be checked.

About the oil on the piston - are you sure its oil? If the carb is flooding, it may be fuel. If it IS oil, it could be a clogged breather, or the rings need to be replaced along with a reboring of the cylinder.

I don't know your mechanical ability, but this machine sounds like it needs some serious attention in order to get it 100%...

I dropped the 726 off at a local small engine repair shop yesterday. Hopefully, it won't be anything major. Thanks for all of the advice.
