Correct, right above that is the intake tube where a sweet nest made of insulation was.Those shiny warped spots are 'Hot Spots' right in an area common with clogged cooling fins that usually cause that in those areas where the shiny spots are in the cylinder.
Yep, 1968 so 53 years old.Then you figure how old that engine is and how long it was run with the clogged cooling fins to cause that. That mower was popular 40 plus years ago. That unit could be going on close to 50 years in age by now, I have a couple of them from new. They just sit in the garage now.
I have a pdf of the IPL for this engine, almost every part you can look up on eBay and someone has a bunch of NOS they're trying to offload relatively cheaply. There's even a few bronze gears for the pto shaft out there.That engine used the camshaft driven PTO to drive the wheels. They haven't been produced in decades plus being the 'L' head engine, you can tell it is old and getting new parts for them will not be that easy due to its age.
I rebuilt one 15 years ago, the parts were hard to get then. I ran it for a few years and when it died, I just left it sit and let one of my older Honda's take its place.
That's awesome. Now I'm really glad I nabbed this up. Maybe I'll go ahead and do a full resto on it.They did have excellent traction for the steep hills I have, that's why I liked it.
The old Hahn Eclipse mowers were tied in with Gravely back in the 60's and early 70's, Gravely dealerships used to sell them.
The Hahn Eclipse mowers I have, have the Gravely name stamped on them with the Hahn name.
They were a good tough mower that were built to last and take a lot of abuse.
