Jonny-Jimbo Posted April 12, 2016 Share Posted April 12, 2016 Hi all,Just out of interest, what is the correct dissy for a TR5, and what should the advance be set to? I ask as my Mk1 has a TR5 cam and HS6 carbs on a long intake manifold, so I thought the TR5 is about the nearest to stock.Following issues on the HCR I am trying to ascertain if I should get the standard 22D dissy rebuilt, and then what it should be timed to.Thanks, Jon Quote Link to comment Share on other sites More sharing options...
garyf Posted April 12, 2016 Share Posted April 12, 2016 JonYes Lucas 22 D6, Part Number 41219B for A TR5.According to my Haynes manual maximum advance 12 Degree's for the Early type and 16 Degrees at 4,000 RPM, for the later versions.At 2,000 RPM max 6 Degree's early Max 8 Degree's for the later version.No Vacuum advance on the 5 either?If you have carbs fitted maybe A vacuum advance type may be more suitable, I'm sure someone will tell you?

piman Posted April 13, 2016 Share Posted April 13, 2016 Hello Gary, it's not whether the engine is a carburettor engine or not but how they are set up. If the TR 250 is of a similar spec to Gary's and it used a vacuum distributor then if those needles are used and the correct vacuum module is fitted, then yes it may be the one to go for?Alec Quote Link to comment Share on other sites More sharing options...
