Hi, I have just joined the forum. I live near Shaftesbury in Dorset and have a 1979 T10E which is up and running, and a 1956 TRW 500 side-valve which isn't! The TRW is a refurb project and I need some parts to finish, so if anyone knows of a source of TRW 500 parts please let me know. And a technical question relating to the T10E - has anyone replaced the standard Champion N5C plugs with any hotter plugs and noticed any improvement in cold starting? I have seen conflicting advice on the interweb so am inclined to stick with the standard plugs, but am interested in hearing if anyone has moved to hotter plugs and what the outcome was. I have never experienced cold starting problems with previous Bonnies, but they were "V's" rather than the "E" and this could make a difference........? All the Best, Pete
