Hmmm , I wonder if he will return to you in a months time for the Quick 8 minute exup valve service now that its functioning OK ? Sounds to me as there is probably a lot of Gen 1s out there bogging around out there with seized or semi seized valves ........ and if thats the case all the moving parts are well worn by now and all the Copper grease in the world aint going to replace that worn metal. Bin the Bitch. :lol
