Hi all, its been a while but my beautiful engine has my full attention once more... I have the engine in my workshop currently and I am just looking at giving it a once over. I noticed yesterday that when I spin the flywheel by hand, it is very tight in one area, and requires a fair amount of force to complete the full revolution by hand...
Can anyone comment on this or point out what I should be looking for....
much appreciated- and hope all are having a happy new year |

If it was a salt water engine, I would suspect expansion in the water jacket, If this is what is happening. It will get worse if you do nothing about it. Did you fill the water jacket with anti-freeze or oil?
when put in storage? This would slow the salts from attacking the water jacket and expanding. If this is a fresh water engine, It could be rust in the cylinder from lack of oil. Its time to look closer |

Hi Roger, thank you for your response. It is a salt water engine and no, I have had no oil or anti freeze in the water jacket I am afraid to say. (for future reference, is it just a matter of filling the brass behind the flywheel with anti freeze?)
so please excuse my ignorance, I am better with timber than I am with the mechanics, what are my next steps? |

If it tightens up on the compression stroke I believe you need to pull the cylinder off. Take all assy's off. Clean what you can from the water jacket though the water inlet and out put holes, Blow compressed air too remove loose stuff. you will have to hone the cylinder to make the piston move properly again. I have not tried using an electrolysis bath to remove some rust. I am sure someone will speak up here, but this could help |

Roger thank you for taking the time to reply. I will get started on that tonight... by chance do you know what size hone i will need for the cylinder- cant seem to find a measurement and would like to get hold of one before i take it apart
Kind regards, Pete |

You won't know till you pull the cylinder and measure it |
