t bone and dick: Thanks for the help and ideas. I have a manual for that tractor (just operators manual), and it states how to adjust the idle adjusting screw. But, the fuel shut off solenoid "permits full fuel flow through the main jet when energized". The "full fuel flow is stopped when the solenoid is de-energized". And that is it as far as adjustments to the carb is concerned. Now, the main jet, that is part of the solenoid does have two different size orifices listed in the parts manual. And you are right in that it may be the wrong size orifice. I will order the one that is supposed to work for this carb on Monday and see if it is the same size. I bought this tractor when it was hardly used at all, and it ran fine for the first few years. It is possible that someone could have changed jets on the solenoid when I had the carb worked on years ago. I will change the float level to allow less fuel in the reservoir as you suggested. There is one peculiarity that I haven't mentioned. This tractor does have a fuel pump. (I changed it too!). When the tractor is shut down after using it, everything is fine. When I go back several hours later, there is a tiny bit of fuel seeping from the air intake side of the carb. This continues to seep when the tractor is not being used. When I start the tractor up and start using it, this fuel seep dries up after a few minutes of operation. Not sure what thatt indicates, but thought I would mention it. I thought that the housing might be cracked on the carb, but if it is, it is invisible to the naked eye. Anyway, if persistence pays, I should find it someday. Thanks for your help !!!!

When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
