[PIC] Is this the wrong piston ring? (pin gap)

It measures the right diameter 43mm but the gap looks too big.

Either that piston is larger than 43mm, or that ring is less than 43mm.

What kit is it?

Re: [PIC] Is this the wrong piston ring? (pin gap)

Morini Polini 65cc reed valve kit. I thought the ring was the Polini D.43x2 (205.0071).

You agree though that the ring should close snugly around that pin? Shit, no clue where I'm going to find a replacement...

Re: [PIC] Is this the wrong piston ring? (pin gap)

I thought so, but I must have something else. I don't know where I got this one from... it's been sitting in storage for a few years. I'm going to try ordering another (actual?) 205.0071 from my local Polini distributor.

Hopefully whatever it is that I have currently is not really a D.43x2. Thanks for the input.
