Hi Bill,
Try eBay for a carb, using your model number off the carb.
I replaced the carb on my Tecumseh HS-40 with a cheap chinese? carb and it works great. I just had to swap choke arms as the new one had a different one than the original.
Cost of the complete carb was only a few bucks more than a rebuild kit,,,such a deal,,,LOL.
Regards
Jeff
