well the replacement I ordered from TEMU because it had a 1/2" hole reach instead of 19mm just arrived.
I was so excited..
Lucky I was not pinning my hopes on that and found that old NGK I mentioned...because this thing is some series plug with SMALLER DIAMETER HOLE..never even seen one with smaller diameter hole b4..described as suiting many scooters and stuff...hole reach matched what I wanted, centre electrode looked about right length...5/8 hex...I assumed that was all the specs I needed...
never counted on a plughole diameter looks like you could put it in a COX/TAIPAN 2.5cc RC model-airplane engine..
