chrishawley Posted February 26, 2023 Report Share Posted February 26, 2023 I'd be interested to know what the tags on a fully original vehicle say. As far as the books go: Ops manual for GT6 say that CDSEVs were used on the 'late' models - that'll be 3507. But Haynes seems to suggest that 3432 (CDSE) was also possible up to 1974. So much for books! Only difference between the two is that SEVs have a float chamber vent valve. Otherwise the same including the same needle spec (B5CF). I'm pondering your non-starting situation. What remedies have been tried thus far? Link to comment Share on other sites More sharing options...
dougbgt6 Posted February 26, 2023 Report Share Posted February 26, 2023 Chris, I have promised Euan I will report on my carb tab when I return to civilisation on Tuesday. My GT is a 73 which I bought in 78, so pretty sure tab is original. Doug Link to comment Share on other sites More sharing options...
euan douglas Posted February 26, 2023 Author Report Share Posted February 26, 2023 Chris Thanks to your list of things to look at I found the simplest was the problem - one of the Carb breather hoses was badly split so sucking in loads of fresh air while trying to start. A new hose fixed the problem, thanks for your help. Yes, I too am a bit confused by all the numbers on carbs and what mine should be - not that it really matters after 50 years as long as it goes well! Looking forward to seeing what Doug says.
