I have a M JOhn Deere here that runs good till it warms up
then it misses and runs bad
never dying
Cleaned Carb,Adj points
I did spray wd 40 on and around intake manifold while running and it lined out for a time
Im thinking Intake gasket or bad intake manifold
Am I missing any other potential problems
Thanks
Pete
 
Take a look at the photo below.

Note the wear on the top edges of the contacts/terminals.

"Mac" one of our 1951 MTs was running rough and eventually quit running.

Had power to the points, but no power to the plugs.

Changed the distributor cap and rotor and now tractor runs good.

Hope this helps.
 
My MT did this to me. I put in a new coil, rebuilt the distributor, new plugs and wires and timed with a timing light and solved all the issues. Not sure which item "fixed" it but the tune up made it run like a top. Cost about $250 in parts and shipping.
 
Pete, also try another condenser.. If what everyone else suggests doesn't work
a bad condenser will screw up the whole works.
 
RLA,
no I haven't had time to get to it but when I do,Ill post the results
Ill replace the dist cap,condencer and check the intake manifold for leaks
thanks
