186 that stalls at lights

G'day all,

I've recently picked up an EH special wagon that has had a 186 and trimatic transplanted into it at some stage. The car starts and runs fine but when it heats up it will stall at traffic lights (or whenever it stops). Once placed back into park it starts straight away and will happily cruise until the next time it stops and then stalls again. I've changed plugs, leads, coil, fuel filter (no points - has electric dizzy). The car will also idle fine in park while in the driveway. Has anyone had a similar problem or offer any suggestions before I start pulling the carby down? Cheers Brent.

I’ve got an AP5 Valiant that does the exact same thing, If stopped at lights for instance, I whack it into neutral and keep the revs up until I move off, not ideal I know but for the amount I drive it I just learned to live with it.

Try not pulling up to a complete stop too sharply in D more like slowly come to a stop or slip it into N before you pull up then back in D when taking off. I agree having higher revs than recommended - but when did you last change your tranny fluid (with a tranny filter kit) before touching carbie as could be old tranny fluid.

if the idle speed in drive is ok - maybe it's running too lean at idle...when cold and with choke closed it's rich enough but when warm and choke open it's too lean...check that you don't have an air leak around the inlet manifold or somewhere (throttle shaft or carby gasket) - tighten the bolts and check/ adjust the idle mixture - just an idea but I'd start by checking idle speed as others have suggested..when cold and with choke the fast idle cam may be increasing the idle enough...

Being a traumatic, have a good look at the vacuum lines, in particular the one that goes to the top of the box.
It has been too long since I played with traumatics, so cannot give any more info than that.
An old school automatic bloke may help.
