I'll see how much it will be to get the rings done. This is way past my ability so I have to pay someone to do it.
not 100% on the carby. I will get the old one and send it to you if you like. I will have no use for it. If you have a use for it then it might as well go to a good home :-)
just called the shop apparently about 45 min to take engine out and same to put back in, then 30min to strip and see what's happening.. sound about right? can't recall what their rate is but say 60 that's 120 without parts and without fixing anything. depending on what is wrong the next cost will be variable..
If I put a different engine then I can try and sell the old one on ebay to someone that can fix it.
