Its the engine that stops me, I can bore the engine and fit a overdim piston, or find a better engine but its still a small engine thats 50 years old and made i very small series so parts ar hard to get and very expensive.
There are the options on a Loncin or Honda engine, Loncin have the right PTO size and are cheap.
Well, I always say a running machine with an engine conversion will get more work done than a broken machine that's all original waiting years for a part. There are a few on the site that have converted Gravelys from their original engine to the Chondas (Chinese Hondas). It just depends on what you as the owner want as a finished product.
The plan is to make it a working machine, its been here since it was new and it was run whit a broken headgasket until the head it self was destroid by the leak.
The machine is swiss made so its no cheap design so if i get it working good i have it for decades.
Yes AEBI is swiss and still made today, there use to be a US distributor in the northeastern US, I imagine they are still there. Even current models look very robust, I would guess they are also spendy.
