i have a 1500 1978 Spitfire. Recently changed Carb jets and needles and got them set up. Also did service and car was running sweet and did 120 mile journey with no problems. Now without any adjustment she wont start and just backfires as it tries to start. I have checked Choke is pulling carb jets down alright and cant see anything else obvious. Dont want to just into taking carbs apart or adjusting settings. Any idea???
