Yeah, well, they don't...Liners is a different story, I don't know how fast those "seat", but I guess the moment you fit them and tighten the head bolts the liner has "seated", but rings take at...

I find rings seat noticably better, if the engine has been pre-lubed before first start, and as soon as possible after the very first start, after a short warm-up (say, 30 secs) the engine is given a...

Mind you: a honed liner and a new ring, means a full break in period, since liner and ring are THE parts that are most in need of a proper break in as well as needing the most time to do so. No...

Well, be that as it may... when you're selling via e-bay, the buyer has no chance to inspect the engine or see it run before the deal is done. That is quite a difference with someone buying the item...

So... you're selling a worn out 85 pound engine for which the worn out parts cost 60 pounds to replace?

Apologies if this comes across as a bit brash, but...IDK, that seems like a really dumb idea...

To be honest, I have done the job both wet and dry, and prefer to do it dry: Easier to clean that way and as you say, cleaning is extremely important. On a machine hone I'd probably use some oil, but...

I was not aware of that info (the 400~600 thing). I have always used 240 or similar on larger engines and compressors and the likes, and simply pushed less hard when doing model engines. I'll have a...

I had to check visually what 220 grade is, but that would be about the coarsest i would go. Many light cuts are better than a few rough ones, so go light. About the pressure of rubbing an itchy nose,...
