I have a 4 hp Atlantic in the rebuild stage. Should I hone the cylinder ID before installing the piston? From the "Old Marine Engines' book it noted that the cylinders were 'polished' so I don't know if that is honed or polished. Any experience out there? |

Roger, a lot depends on the condition of the cylinder and if it had compression before you started. Are you replacing rings, was the cylinder rusty? |

The engine was rebuilt in 1977 at Lunenburg and then stored in a basement in Edmonton Alberta for 37 years. No rust other than some surface rust on the cylinder but I don't see any hone pattern on the walls.
I assume there was good compression circa 1977.
Not planning on replacing rings, all look good and no running hours since rebuild. I assume they were new at rebuild and as I say look real good. |

A light honing to get a crosshatch pattern shouldn't hurt. |

I went to machine shop a few weeks ago i done a full rebuild on a 5 atlantic and i found a broken ring. Took the cylinder and one of the rings with me and they made a ring for me out of some cast. I had to do some filing but no issues. |
