Hi All, I am taking my two young sons camping tomorrow and as the weather is favourable I thought I'd take my 1975 Series III SWB. So today I did the usual checks before the 1.5 drive to the new Forest. I had been meaning to tighten up the top of the exhaust to the bottom of the exhaust manifold as its been farting and popping for months. So after administering a bit of WD40 I succesfully tightend it up and now there is no play or blow from the joint. Pleased with this i fired her up to see if the farting and popping had stopped - it has. However it now wont idle and on going for a run the engine cuts out when not on the gas or when slowing for a junction etc. What have I done!? it idle'd beautifully before. (It did do this back in the spring which I remedied by removing the large bore air hose from the top of the Carb and dribbling in some neat RedEx that solved the problem) Any words of wisdom before I tinker more and make matters worse?

have you tried to adjust the idle? tick over, advance it a bit and it should solve your problem. failing that if the truck has bein standing for a long period of time maybe pulled some crap up through the tank, so its starveing on feul, check your filter see if the feul is clean maybe evan change it if you have a spare to hand?

hope its a help to you,

p,s ive noticed its in the wrong section perhaps correct this and you will get more help hopefully

Thanks for the response - I am a novice to say the least. when you say advance the idle I know what you mean - but dont know how you acomplish this.. can you give me an idiots guide? I'll get the haynes manual out too. thanks. M.

thanks! will see if I can post more broadly.

its ok.. its called the dynamic timeing, around the base of the injector pump should be 3 13mm bolts, (may evan be 10mm) un do them slightly and the pump should twist, anti clockwise and clockwise, 1 way will advance the fueling to ease starting the outher way would decrease the feul makeing more of a delay in starting, once its running you can adjust it while running.

its bein a while since ive played with a series but this should help you some what.

found this not the best vid but you'l get some idea from it

Sorry I should have pointed out that mine is a 2.25 PETROL engine..

You need to adjust the idle screw on the side of the carb. Here is a pic from the 'green bible' of the relevant part (assuming that you have a zenith 36IV) - http://i.imgur.com/B76t9xc.jpg
