Hi Club Enya.
There are 2 Enya 60X which I bought from the big bay.
The one on the left is a non-ringed one in pretty much used condition, few fins at the cylinder head are partially cracked and bent. The right one is of ringed type, piston, ring and liner look like new parts from overhaul work. Carburetor seems to be the same on both ones.
The cylinder heads are different β the non-ringed 60X has a much more massive head, while the head of the ringed one has less material. Fin height seems to be identical.
On pics 3 and 4 it is visible that the combustion chamber is different, too. The non-ringed 60X has much deeper bowl, resulting in larger chamber volume. The chamber of the ringed 60X is more flat, and together with the reduced head thickness even the glow plug little bit sticks out.
Is this a low compression head on the non-ringed one versus a high-comp head on the ringed engine? So far I thought that Enya made such 2 different heads only for older, smaller engines.
Looking forward to your comments.
