i always where possible disconnect the battery , working fine

hi 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

bottom adjuster thames barrier type, breather blocked off breath on rocker to a breather filter , was running fine before going on ramps , just strange it is 2 cylinders 3and 4 not firing paul

will be something simple i bet will get to it paul

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

thank you that helps a lot paul

ok graham 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.

thanks pete will help , i have a collection of various manuals from 70s 80s in similar condition 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

so it is should have had a better look paul

sure the centre bit on the herald 12/50 grill is the same part might find a 12/50 grill on ebay

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

hi just purchased a 1975 viva , advice please . came with a flat battery so charged up today car fired straight up runs well , the problem i have is no dash display , no warning lights no wipers no indicators . working lights horn temp fuel gauge, put tester on battery not charging has a alternator fitted checked fuses not blown . not sure where to start could it be a earth problem paul

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

if it helps coated both sides have done 2 1600 heads can get a bit messi . i used a small synthetic paint brush and wellseal ,

have fitted before over the years no problem , so yesterday remove points ect fitted new powerspark just spun over no hint of firing had the distributor slightly unbolted so gave it a slight turn advance and retard still no intention of firing .so points back on fired straight up .i contacted the supplier by email no contact number the answer was its a easy fix did not say what though, still waiting a reply think i will stay with the points system, any one had problems with this product paul .
