Condenser sounds like the culprit, coils usually start cold and go bad quickly (like it is out of time then stop working) when they worm up. Also look at the plugs and plug wires/coil wire and connections. Plugs go south relatively fast if the carb is out of tune on the TD,WD 9's. They are a very hot plug range Um D49 D I think. Spendy puppies for the right plugs. .23 thousands of an inch is proper gap I think.
ALSO make sure the butterflies are working.. reach up and flip the L shaped lever up and down it should be springy and spring back up. if it don't spring back up by itself spray some Marvel Mystery Oil on the linkage on the that side of the motor. I had the same trouble with my TD9 and LOOK FOR OBSTRUCTION in behind the manifold and linkage..I had to use my cell phone to take a picture and found an old starting fluid cap stuck between the manifold and shaft that operates the butterflies.
You can check the condenser by arcing it across a battery then have someone touch both ends, OR you could touch both ends, OR use a tester but it will only spike the needle... Where is the fun in that???
Good Luck
