The only engine I have ever managed to seize was a Lambretta scooter on a hot summers day I drove it from Manchester to London BEFORE there was a motorway link, so it was all A and B roads. What is now a 195 mile journey would have been 250 or even more on our wiggly little roads.It took most of the day and for most of the time I was leatherin it .. When I arrived at the hospital my girlfriend was awaiting my arrival and we had loads of catching up to so The next day, after we'd finished catching up, we decided to drive up to a place just past Windsor and I had foolishly not checked the oil level <sigh> Has we entered Old Windsor and we were going past the bottom end of the castle there came forth the sound of THOR striking his anvil with great gusto, a cloud of smoke eminated from the exhaust and the back wheel skidded us to a stands. Being the good citizen that I am I ripped off the reg plates pushed it in to the ditch waited to all passing toursits et al had moved on then off we walked to Windsor train station and ultimately back to the hozzie for more catching up.Now I know that some here would like that old Lambretta, and as far as I know it may still be there

I had a Lambretta scooter - but mine was a 2 stroke engine which didn't have oil in it. You mixed it with the petrol.

Ya mean to say that there was no SUMP oil for the big end and crank. You mean that a tiny bit of oil added to a litre of petrol lubricated the con rod, small end and big end bearings. I step back in amazement

I step back in amazement On the Lambretta the crankcase space under the piston draws petrol/oil vapour from the carburettor on the up stroke and pushes it into the cylinder on the downstroke - hence 2 stroke. If you had a pool of oil in the crankcase it would be shot up into the cylinder. Hence the lubrication of the crank, small end and piston is via the oil in the petrol.Study this and be prepared to answer questions.....HowStuffWorks "How Two-stroke Engines Work"
