2HP Ottawa log saw Hit Miss Engine hopper/cylinder l. The bore looks good however there is some rust scale build up and will require some hone work and a lot of cleaning. I don’t see any major pitting. Igniter bolt hole pattern looks to measure 2 apart on centers. One stud/bolt is missing and the threads going into the block are stripped out. A heli coil are larger bolt will be required before being able to use it!!! Bolt pattern for where the water hopper/cylinder bolts onto a block measures 3 11/16″ x 6″ on center. See pictures for the absolute best description. This item is old, used, and has wear. Not bolt on ready! Will need work before installation.
