Spent the morning in the tractor shed doing more diagnostic discoveries on my Farmall 140 that I can't get to start and run. Removed the hood and spark plugs planning on getting a look at the valve train following what I was going to find on a compression test of the cylinders. I checked them dry (didn't put oil in the cylinders to better seal the rings to sleeve) and found them all at 150 PSI. There was maybe a pound or two at most difference between any of them. With those results didn't think I had a valve issue so didn't pull the valve cover as it was obvious they were all working and sealing well. Drained all the fuel that was still in the fuel tank which was about 5 gallons. Drained it through the fuel line to the carb and it all ran out in about 15 minutes of less. A good steady flow through a 3/8" dia. hose. Removed the carb and it was really ready for a good cleaning for sure. I'm guessing with the very good compression along with the fuel flow and spark plugs with no evidence of getting any fuel since they were so dry the issue is getting fuel sucked through the carb. The carb is now soaking and will get it back together once I get the carb kit I'm ordering from Rustyfarmall by email. Trust it will arrive shortly like his parts always do. So that's the findings at this point - I think in the future I'm going to shut off the fuel at the tank and burn up all the gas in the carb before shutting them down in the shed for those not used on a frequent basis. Thanks for the responses to my initial thread on this issue. I'm still thinking those replies suggesting to prime the cylinders with gas and then trying to start it might have broken the obstruction loose but after seeing the inside of the carb feel I took the correct approach. Thanks again for supporting this "won't start" issue, Hal.

Today's Featured Article - Women and Tractors - Tractor Engine Repair - by Teri Burkholder. One of the great things about working on a tractor engine with your other half is that you know what he is thinking of at all times and can anticipate his every move and his next thought of what he will do. With Ben, anyway, I can tell! He'll be busy working and I’m handing him tools and he says, "give me that..." and I’ve already got it in his hand or "hand me that....."and I’ve got the portable light right where he needed it placed to see.
