hi i am now the proud? owner of an old stuart p55, it is seized up but i think the rest of it is ok, how should i unsieze it? put a bit of diesel down the cylinder and leave for a day or 2?
am i being stupid because i cant find the throttle! (probably) or is the small lever below the gear handle, i assumed this was the clutch,
any help would be apreciated! |

Seizing - Penetrating oil (Plus Gas or diesel) are both good. Fill through the spark plugs and leave for as long as you can (weeks are better than days). If you have a big enough spanner and can access the flywheel nut, some (gentle) tapping should free your engine.
It's possible that your engine has aluminium pistons. These can be difficult to free because the oxide expands in the bore and 'welds' to it. Patience, diesel, a spanner and a hammer are your best friends. If you get really, really stuck, try to get the head off and play a blow lamp in the bores This will cause them to expand. Avoid directly heating the pistons as this will make matters worse. Place a piece of wood on the crown of higher piston and wallop it.
Stand by for a number of ST enthusiasts shouting at me for suggesting this course of action. It's severe (you may need new pistons) but was the only thing that worked for me a while back. I'd strongly advocate the 'diesel route' first. |

thank you, i will bear that in mind once i get the engine back to my houseas it about 20 miles away in a barn, in a boat, which has fallen down a hill (barn and all!) so i somehow need to extract the engine from the boat, extract the boat from the barn and not bother with extracting the barn! thank you! |

Folks,
Turpentine works well for loosening stuck items.
