    I think its time to rebuild my fx140 engine mr1 =(

    my mr1 was used on the beach and storage to about half a month, now we tried to start the engine the relay will only click, checked the starter ok, removed everything, pull out the engine, removed the reduction gear and front stator, still the same engine won't turn =( checked the intake valves, there are some rust...

    It's probably Loctite 572. It can be hard to find. You can substitute Permatex 592, which is not only cheaper, but probably better.

    opened the engine...cleaned the pistons and sleeves from rust

    here's the pictures, is the sleeve still ok? what do you think?

    Looks pretty pitted from the photo, but hard to tell. On the FX140 the cylinders are steel bore and oversized pistons are available, so I'd look at going with a rebore and new pistons. You are really going to have some work on the head if it is as bad as it looks in the photo (might be better off with an exchange).
