Hi BT & MF, so that scoring looks excessive does it? I didn't think it was that bad? And you say it's a result of straight fuel and not 2-stroke?

So even though I've got compression, it won't run? Why's that? And is my only option here to hone it and install an oversized piston?

If so, my question then is... if I have good compression now, what's the difference between having it now and having it with a honed bore and new piston?

To be clear, I'm not doubting you, I'm asking so I can learn smile

Cheers in advance.
