i have no idea wats up with it!

fuses are fine

all leads are on

got fuel

chokes working

how can i sort this? and fast

it will drive fine but when i stop at a junction clutch down with no accelerator it dies!!?

then other times it will be fine? any ideas?

your idle screw on the carb needs adjusting
try turning it half a turn at a time

surely its not though as it runs fine other times? i have no idea wat it could be!

could new plugs and leads sort this?

^note that reads IDLE screw, NOT mixture screw. The idle screw only affects mixture/throttle at idle - no difference once the revs rise.

Mine has just done exact same, replaced the rubber o ring on idle screw, and adjusted screw. Started back up, n touch wood never had it again. Cheap fix/ worth trying.
You will be surprised Lol. Simple engines, simple faults.

I am having the exact same problem, i just cannot get it to idle. Did you manage to sort the issue and if so what was it? I have had the carb apart numerous amounts of times now, these o rings? would these be included in a carb rebuild kit? if this is the case then this is surely the only option? i have replaced the flange between the carb and the manifold thinking there was a possible air leak. and made up a new gasket for the carb body so the only thing left to do now would be to buy a kit and just rebuild the carb?! Any Ideas?!!?!?!?! PLEASE! ha

Oli, What carb have you got?

check your idle cut off valve is working correctly

Oh go on, I'll say it as well. There's an idle issue.

Or, there's a vacuum issue - check the vacuum diaphragm on the back of the distributor for functionality.

I had this with mine.

New carb mount, as it had disintegrated, and a play with the idle screw sorted it.  

Happened with mine too!
I got a rebuild kit for the original carb (solex pict7)
changed all the diaphrams, o rings etc, cleaned everything out with a decent carb cleaner, changed the carb/intake gasket, and its been sweet ever since!

I think mine was mainly due to crap being inside the carb ( previous owner let her sit for ages so there were fuel crystals )
