hi
49 minutes ago, Iain T said:Surely it can't be a carb or fuel problem as with a single carb all four cylinders would be effected. It must, and I use that word cautiously, be an electrical fault on 3 and 4 only. Try swapping leads and plugs?
Iain
been on it a couple of hours now swapped leads around changed leads cleaned plugs swopped around cleaned points swopped coil for a known one , has no ballast running a 12v coil so i thought would try and bypass the ignition switch in doing so the engine starts fine but shuts off dead after a few seconds , so back to running from switch ,if left running for around 15 min the engine will just shut off dead got to be electrical my thinking but what. does take a couple of cranks to start again though , thinking as you said can not be carb what next though , just to add engine does not overheat starts on the button from cold little choke although only running on 2 pots

just a thought could the diaphragm cause a problem if has a small hole to be honest all the years i have owned triumphs never had one fail so not sure of symptoms . spoken to owner said was topping up dash pot a lot lately ?

pete done the dizzy checks all fine , pull the lead on 3 engine runs the same as 4 no backfire engine just jumping all over the place , feels like sticking valves but it cant be ?

have the air filter off do you think it could be carb related number 3 and 4 not firing not come across this before strange it was running badly on 4 at one point , not even my car a favour job now my problem paul

well not going well , started on the button from cold choke in running like on 3 again , blew fuel lines through checked have a good fuel supply all good . so then started the car removed each lead all made the engine note change the back as i touched the lead back onto the plug so seemed all good , coffee time so indoors 30 minutes went back out restarted even worse than before now not running on 3and 4 , took plugs out dry leads ok . suppose next compression test not making sense though drove on the ramp fine was driving well . forgot to mention its a 1300 engine on a single stromberg 150 , thoughts please paul

thanks all will let you know what i find paul

was running very well , looks like i will have to start checking fuel and electrics have a spark on all cylinders though

strange one reversed spitfire up onto ramps to do a bit of welding shot up no problem. following 1 week started it yesterday started first time but runs like a bag of old nails seems to be on 3 cylinders strange as only opend the bonnet to disconnect the battery . done all the usual checks plugs leads ect . only thing i can think of is muck in the carb was a bit low on fuel , thoughts please paul

Wonder if the attached diagram might provide some illumination. Assuming you currently have an ACR series alternator then the pin-outs would be one of the three illustrated. I hadn't noticed before that while the ACR standard connections had an earth lead to earth the Euro connection didn't. So (obviously) if using a Euro connector the earth would not be used.
thank you that helps a lot paul

ok graham
8 minutes ago, GrahamB said:I suggest that you study the wiring diagram for a model fitted with the single plug alternator; both large spade terminals connected directly to the battery +ve and the smaller spade terminal connected to the warning lamp (which must not be an LED). The wiring diagram suggests in theory it should be quite easy but in practice??
will do was hoping was going to be a simple case of joining wires paul

my herald came fitted with a alternator with 2 plugs in the back , it is playing up bearing noise not charging , how can i change the wiring to a single plug alternator a lot less money with the single plug paul.

this one is not that bad bit welding on front floor pans . downside has been hand painted some years ago good bit excellent interior

done a check on fuses all ok . cleaned the terminals on the fuse box still the same, noticed a broken terminal on the solenoid found one in the shed but slightly different layout, so have 2 white wires which if i connect the engine will not turn off with the key have tried different positions then nothing when i turn the key .have left disconnected starts on key turns off on key thinking the 2 white wires could be the problem .waiting for a workshop manual can the go through the wiring diagram
-
all in place on the solenoid will do a test tomorrow pete

of course it matters, It is fraud however you look at it
i agree but it went on a lot , you used to see 1972 v5 with chassis plate for sale all the time who knows how many classics are not quite what they should be a lot for sure paul
