This morning I removed the starter belt and wrapped a rope around the pulley and gave her a yank and it fired up and after adjusting the carb ran fine. Looked at the starter/generator and saw that the pulley was only about 2" in diameter so I pulled a three inch pulley off another starter/generator, swapped them out and presto she fired up. Called the owner and it turns out he switched starter/generators when the initial problems started awhile back. My only issue is why the engine and starter/generator are all the same color though but perhaps he only changed the pulley..
I am not questioning your mechanical abilities, so please don't take my comments that way!
All of the Wisconsin S-7D, S-8D, TR-10D, TRA-10D, TRA-12D engines used on the Bolens Tube-Frame models used the same starter pulley (Bolens part # 1708293). .....This was the small-diameter pulley.
engines on the tube-frames used starter pulley (Bolens part) # 1713855, which I believe may have been the larger diameter.
The S-12D & S14-D Wisconsin engines on Large Frame (models 1250, 1455, 1476) used a starter pulley having Bolens part #1719146.
Changing the pulley to a larger diameter obviously got the engine to start, but I'm wondering if that didn't mask the real problem of an under-performing or failing starter, which is not cranking the engine fast enough.
I speculate that the size of the starter pulley is based on the diameter of the pulley mounted to the flywheel. .....By changing to a larger pulley on the starter/generator, charging output may suffer, while cranking rpm's will increase.
