I recently picked up a few cylinders in a bulk buy. Need help with this one. Cylinder head is marked A-67874-A. Thought this was for a SEZ. But then I noticed that the decomp valve port is not there. The box it came in reads: A78418. Anyone know what this cylinder is for? Any help would be greatly appreciated.

Looks like it may be a replacement cylinder for a XL1 or early Super Mini without decomp. www.youtube.com/watch?v=hT4-4hDFWfU

I have a Super Mini with that cylinder number, A-67874-A cast into it.
It also shows up on the Super EZ IPL. The 41 cc XL-1's I have don't have the decomp boss on them.
Not sure why it wouldn't be machined for the decomp.

I have two 1-9/16 Super Mini cylinders with that part stamp. Both have the decompression valve machined in though.
This is actually second one seen with the port blocked. Someone on AS had posted something similar a few months back. I think that one was blocked off though.
Is that one factory blocked does it look like someone plugged it?

Cylinder - A78418 , is for an XL-1 Automatic , IPL: 78329 ..
This model and some others were automatic oiling only and had no decompression valve .

Thanks to everyone for the help! This one had me stumped. I think the stamping on the cylinder is what confused me. I couldn't find anything on the A78418 number...guess I didn't search hard enough. Thanks for the info 5Terrysupersaws!
