McCormick-Deering 10-20 finally runs!!!

The resurrection is complete!! This is the 1925 tractor on steel that I couldn't get started after having the motor rebuilt. Motor guy in OK wouldn't respond to calls. I bought a leak down tester today and as soon as I put air in a cylinder I could hear air coming out of the exhaust pipe. I also felt air coming out of the #2 plug hole while testing #1. BINGO - values not adjusted right. I loosened the nuts, backed the tension off of the value spring, air noise went away.

I had previously rebuilt the carb (float needle problem - solved from this forum, it works great), timed the mag (solved from this forum and I had it timed right). So now it was time to try and start it.

Now that I actually HAD compression at TDC, I cranked 2 times and bingo. The motor ran for 5 seconds. I reprimed the motor and fired it again. 5 seconds and it quit. I readjusted the air fuel mixture and the idle, reprimed and then I had a running 10-20!! I let it run for 20 minutes to watch for water, fuel, and oil leaks.

No water problems, a tiny drip from the bottom of the carb but I had oil coming out of the top of the filter pretty bad. There must be some gasket or something missing. I grabbed my dirty extra oil filter cover and the fit was snugger so I just stuck it on and fired the motor back up. No oil leak from the filter. Still have a leaky oil pan.

It was storming out but I didn't care. I crammed it in 3rd gear and popped the clutch to take a drive. I drove it a mile in a downpour until the lightning got too close. I didn't think driving a steel wheel tractor was too smart.

Anyway, time to button it up. I put the clutch cover back on, valve cover on. I have the oil pan off and the oil filter cover off. I have cleaned them up and ready to repaint them tomorrow and reinstall.

Both 10-20s now will be able to go to the IH show in Roseville, IA over Labor Day AND go back to the farm where they came from 2 years ago. I will park them where I pulled them from and take a nice before and after picture. Grandma can see them and my uncles that drove them as kids can drive them around the home place.

Thanks to everyone on this site who helped me with these tractors. I have learned a great deal and have enjoyed it all.

Dave, it looks great and GREATEST CONGRATULATIONS on restoring it! I hope you'll help me when I need it. I intend bringing my family's very first tractor--(10-20) the actual one--down to Texas from its home in Nebraska after Labor Day Weekend. I've seen several of your posts and questions and am very glad to have seen this success! All the best. kelly
 
Dave-
Glad to hear you got it running. Will be looking for both at the show. What is a 1925 doing with an oil filter? Engine swap?
 

Great to see you have it running! It sure looks pretty too.

If you haven't adjusted them to specs yet, with it warmed up, set the valve gap around .010 to .012 and you should be good to go.
