Waiting on rings & gaskets to put an SXL back together. I saw a video on the Baileys website the other day about using a Flexi-hone to re-surface cylinder walls. They claim this is safe for both Nikasil and Chrome plated bores and it is helpful to re-seat new rings. Do you guys hone at ring changes and if so, have you used the Flexi-Hone with satisfactory results ? The local auto parts house wants $117 for this hone....  |

mikem, The Homelite Service Manuals specifically say not to hone the chrome bores. I've never honed them. My thoughts: On cast iron cylinders, the cast iron will actually wear away and on car engines this is evident by the ridge at the top that has to be cut to get the piston out. I've cut some pretty deep ridges in car engines. Because there is a ridge and wear, new round rings won't match the shape of the slightly oval cylinder and therefore the rings have to wear down some and seat themselves to the cylinder. The chrome plating in the Homelite cylinder is pretty thin. If it is worn enough to be our of round, the cylinder is toast. Honing the very thin plating just makes it even thinner. What happens if you go through the plating with the hone  Also, since the head doesn't come off, how will you be able to hone all the way to the top Also, We don't need to control oil getting past the rings. At the high RPMs that theses saw run, there isn't much time for anything to leak past the rings. MY . ____ \/(8/2) |

My hones are all of the spring loaded abrasive bar type and I knew using one of these would be a bad call on a plated bore. I read in the Homelite Manual that it was not recommended to hone cylinders but was not sure if technological changes(ie: construction of the hone) may have changed over the past 35 years. As the cylinder is in reasonable shape....I think I will just leave it alone  Thanks Craig. |
