Hello stylieee,
I dont think its a huge problem. I had a similar thing with mine. I changed the ignition coil and the condenser and all was fine. Mine would tick over ok but when I put the engine under load it spat, farted and died. Check that the ignition coil isn't to warm after a few minutes running.
Regards WP.

and what if all it needs is the ign timing done..five minute job against driving to halfrauds and back to get filter then 20mins to fit the thing once he finds it. if it has one.i still thing he needs to check the easy, no money thngs first.then atleast he can discount them from the list of possible causes.Miniman said:

I'd leave the dizzy. you could open a whole can of worms there and spend a lot of time finding the worms and putting them back.
1980 series 3. I think it could be a small hole in the diaphram of the emission control system. This bit of apparatus is not covered by the Haynes manual.
The diaphram lives in a little house near the carb. It is connected to the carb by a bit of rubber hose and the valve rocker cover by another bit of rubber hose. What often happens is, a hole appears in the rubber diaphram. Air leaks in, dilutes fuel/air mix and when you try to accelerate this air weakens the mixture, at the precise moment it needs to be richened.
It is about 3 inches diameter with some wire clips on the top. Undo clips, take top off and lift out rubber. See if it has a hole in it - you need to be invery good daylight for this.
The symptoms are very similar to ignition problems,distributer, plugs, fuel filter etc.
Do check the emision control. Its a crap system. I stripped it off and put a plug in the hole left in inlet manifold. First time I'd bought a part for motor vehicle from a plumbers merchants!
This is all a bit tricky to describe without a diagram.
I've been to hell and back for 12 months - new dizzy, points, condenser etc. New carb ages ago. Turned out to be this rubber diaphram.
I agree with in line fuel filter. They cost nothing and are easy to fit.

Slob will probably tell me off for being too tekki and wordy - but checking this diaphram will save you loads of time, cash and worry.
not atall matey after years of dealing with series engines i always check the easy bits first. like the dizzy, five minutes and you either found the fault or eliminated the ign from the list of possible causes.then you can check your other bits , best to do it some sort of order and if you find checking diaphrams first is the best way for you then go for it.
i prefer ign, fuel, werid **** in that order

Have to agree. I remember with the old 24v FFR's the VM's (Vehicle Mechanics) first action was always to check the ignition system. this solved way more than half with most of the rest being fuel probs. Wierd probs like all wierd probs generally left everyone scratching their heads
