I have never bothered/needed to work out how to pick the difference between a 125 and a 160 without measuring the bore. I'm guessing you could check the head bolt centers, I'm thinking they might be slightly wider on the 160? I can check tomorrow just curious if anybody knows off hand.

Offset spark plug, bulge on the metal cowl for the decompression valve and head looks smaller when viewed from the front. Love the 125 but the 160 is also great for obvious reasons.

125 has studs and nuts at the base of the cylinder with seperate bolts that hold on the head. 160 has long studs the travel right through the cylinder and the head secured by nuts.

Having said all that I not sure what configuration was in the VC125, would be a Series 70 engine perhaps with a redesigned head to match the 160.

All good, thanks MF and Paul. Looks like apart from the early toecutters I have here they all are 160's I offloaded 15 others for $10 each a while ago but never bothered looking at them, at the time I just had too many mowers here, most would say I still have too many mowers here.

Here I a thread from the past showing Blumbly's VC-125 restoration. Plenty of pics of the 125 engine.
