no its just the cheapest a vernier isnt a precision measuring tool, its accurate but not precision,

you want precision you need a micrometer.

I have the horrible suspicion this is all going to be in vain and I'll be on the hunt for a new engine though

Still cheapest options first!

Redex in your petrol will make the bike smoke like a train mate.
Drain that out and try some fresh petrol and it should clear,
if not then you really do have something wrong with it..

How much is a shot..

Can't remember, it was a small one shot bottle, about £4 max I think, Perhaps i should have taken a vodka shot myself instead?

Good luck mate, hope you get it running sweet. I always think if its running rough that a compression test is worth a shot, if nothing else it will eliminate rings and valve stem seals / leaking valves. It's just a process of elimination sometimes, if not a long process.

Good luck!
