Sorted !!!
Thanks guys, has a good think over a couple of beers last night, and decided to have a go at making a pulley. I don't have a small slide hammer.
3mm thick steel strip with a 6mm hole in it and 4 different lengths of 6mm bolts and they both came out easily in the end.
Didn't even need to heat them up

My next thought was about the cam ???
But a quick pull and wiggle and the whole lot came out. It only left the roller bearing in the far end.

I'll pop into the aquablasters this week and see if he thinks that will be OK left in, I don't fancy trying to get that out
I suppose I could always try and mask it in some way, just to keep the abrasive stuff out as much as possible.
Has anybody removed that inset bearing and re-fitted one, if so how did you do it.?
Anyway, all out and ready to go except that bearing and I need to find somebody with a small spring compressor then the Valves can come out.

Here is the offending stud that needs a clean and re-weld, then tapping, the previous owner must have known it was blowing, the whole area is black around the exhaust port.

Head and Piston/barrel look good, the motor looks like it's in really good condition, apart from that stud. :

Lastly, I'm assuming those pivot pins will need new o rings? am I correct?
Thanks for your help guys, it's really appreciated.
