Today was a great day after a few frustrating weeks with RTW335's air valve which has prevented the bus getting gears. After sending the valve to two normally reliable suppliers for either overhaul or replacement (who did not come up trumps) we eventually had to wave the white flag and send the valve back to Ensignbus who managed to locate a new unit. This was returned to us and quickly refitted. With anticipation we tried to fire up RTW335 but it refused to start - fuel in tank but not fuel at engine where required. Anyway, many man hours later we located a decaying twig blocking the fuel line and finally today (after a few hours overtime!) we got RTW335 mobile with gears again, and it sounds wonderful! It is also (apart from a few minor jobs) ready for painting.
