So I have had a search hoping to find a straight replacment for the flapper unit, but as yet no luck. Can some kind soul please enlighten me on what options are available. Or if there is a good web site that I can have a look at. It would be appreciated.
Thanks for all the info, it had been pushing out black smoke so running a bit rich but yesterday took it to work and now sounds like I am running on 7 cylinders.
