Have you tried the new Drafts feature yet? I just lost a long message today and learned my lesson. It is a good idea to save a draft of any long post you are writing. You can then just keep writing and keep saving a draft, knowing you have a backup if there is a glitch. The draft is automatically deleted when you post the message.

Hi Richard,
                  The only thing holding the barrel should be the 6 base nuts - plus, of course, sheer stubbornness!! Probably some form of gasket cement has been used in the past, which has tried to weld the barrel on. You could try replacing the head, and then with the base nuts undone about 2 turns, try kicking the engine over - the compression may have the required effect and start lifting the barrel. Once the barrel has started to move, it should come off quite easily.
                                     Regards,
                                                Eddie.

great thanks i did not want to force it then find a hidden nut some where,i was thinking about putting head back on and giving some kicks.it has new piston and vavles fitted 20 years ago but not ridden  far since,but it smokes badly so i am hoping rings are stuck.richard.

Hi Richard, Eddies suggestion is a good method, but obviously, don't refit the pushrods when you try it. You could also use a hot air gun to warm the joint - they are quite gentle and will help to soften some jointing compounds.

Cheers,

Neil
