Flipper55 Posted March 27, 2020 Share Posted March 27, 2020 Hi Guys and girls, I live in Guernsey Channel Islands and own since 2006 an ex UK Red Spitfire mkIV 1493cc from year 1977. I am not a mechanic but have enlisted help to get the car to fire up. Replaced and checked all electrics you can mention and rebuilt carbs and reset. Plugs get wet, fuel is fresh, float chambers are clean, running twin SU's, everything that should be there is in good or new condition and connected. We have consulted Haynes and internet and followed all results. We got it to fire and run once we put neat petrol into engine via plug holes and it ran for about 15 mins before we shut off and left for 30 mins then it refired. Would not restart next day. My mate who IS a mechanic is baffled. Any idea what else to check don't mind Q and A on here or via flipperville@hotmail.com or John Bichard on messenger. Go ..........please Quote Link to comment Share on other sites More sharing options...
glang Posted March 27, 2020 Share Posted March 27, 2020 Sounds to me that the choke system might be at fault so the mixture isn't rich enough to start from cold. Once warm or if addition fuel is introduced by hand it seems to fire up.... Quote Link to comment Share on other sites More sharing options...
nang Posted March 28, 2020 Share Posted March 28, 2020 Tend to agree with Glang, It's obvious that ignition is working as is fuel pump. Check that choke 's are working as they should .Are they connected? Good luck. Tony. Quote Link to comment Share on other sites More sharing options...
glang Posted March 28, 2020 Share Posted March 28, 2020 Yes possibly your carbs have wax stat units fitted to control the fuel mixture on starting and they are known to be unreliable so people remove them. If this is confirmed have a search on here and another well known Triumph club site for how to do it👍 Quote Link to comment Share on other sites More sharing options...
Flipper55 Posted March 28, 2020 Author Share Posted March 28, 2020 Quoted from glang- Yes possibly your carbs have wax stat units fitted to control the fuel mixture on starting and they are known to be unreliable so people remove them. If this is confirmed have a search on here and another well known Triumph club site for how to do it👍 Thanks for all the last three posts. I have informed my mechanic and we will look at the points raised but the chokes are connected and working but we didn't know about the wax stat units !!! As soon as the States of Guernsey lift restrictions we are on the case. Thanks again. Quote Link to comment Share on other sites More sharing options...
glang Posted March 28, 2020 Share Posted March 28, 2020 Exactly this subject and how to remove the wax stats is being discussed on another UK Triumph club website at the moment.... Quote Link to comment Share on other sites More sharing options...
