I actually prefer the older engines myself. They may be more difficult to get parts for, but nothing I've had has ever run as smoothly and as long as an older engine.I like the 70's and older ones, and am looking to add another 5s to the collection as soon as I can get the cash saved up. I already have a parts 5s that has bad main bushings and a worn out crank and cylinder.

If I can get the right magneto setup for the Wisconsin in my late grandfathers "Ridge Runner" it should start up with some cleanup. Engine is a 4 cylinder from 1946 out of a haybailer and hasn't stopped running since built the runner in the late 50's/early 60's.

He had a lot of Wisconsins, big fan of them.

On my end, I don't know how hard my 1943 Army Briggs model N was run powering a paint sprayer (still on the base), but it runs like a top on first pull and doesn't blow any smoke at all.

a lot of the life has to do with the maintenance and speed of the engine, i have 3 ihc cub cadets one a 61 one a 68 and one a 71 the 68 was used by my father and me until about 2005 the engine still ran but started getting alot of blow by. it is a 10 hp kohler manual trans. the 61 was rebuilt in 1977 by the previous owner and lasted until last year with a lot of blow by and a bad rod knock 7 hp kohler manual trans. the 71 is a 109 hydro and has to be ran at full speed it has some blow by and a slight knock but still running fine it sat for about 10 years in the 90s. the manual ones ran at a lower speed seem to slightly outlast the same engine ran at full speed all had oil changed usually once a year and and some work but not much except for the 61 being rebuilt years ago. i don't think any new mowers would last this long so i will stick with them.
