This reclamation project has NO numbers on it. But we determined that it's a Bolens Artic 75 Snow Caster. It has a Tecumseh 8-hp engine that was built in a year that ends with the digit 7. So we figure it's a 1978 model. The project is almost done and I would like an owners manual to determine the proper adjustments and the proper lubricants. If anyone could point me in the right direction, I would greatly appreciate it. Thanks a million! Tim
