Cold weather hiccups

Auto choke probably need an adjustment, perhaps turn anti-clockwise a bit to keep the mixture rich bit longer, assuming the issue is mixture getting lean before the engine's warmed up enough.

Does your backfire(hiccup out of intake/carby)?

Choke is wound all the way off (ie, no choke), so yeah, makes sense I'd have that issue haha.

Nah no backfiring.

I have to run the pre-heat in winter or the the carby plays up badly. I run a manual choke and use the hand throttle to bump up the revs to about 1500 RPM. I back off the choke a bit after a couple of minutes. This gets my out onto the main road, and half way into town before its warm enough to run properly.
@dom14. I was told, in harsh terms, to keep the deflector as it will affect the mixture in some of the cylinders.

Take the air cleaner out and see whether the choke flaps are moving after few minutes of cold starting.
The bimetal electrical choke unit fails more often than we would like to see.
I guess you remember my choke rebuild threads! :)

It won't be easy for me to find a one. I'll look around. I guess I can try to panel beat a one out of a piece of pipe and some TIG welding. :)

Nah, I deliberately wound it all the way off. Kept having issues with it, had a trip and was easier to work around having it off and having to let it warm up, than it running like a pig once warm.

Always intended to fix it, but, time and effort and all that.

If you wanna drop in I can fix it for ya for free, or alternatively get rid of it and attach a manual cable to it, so you can open and close the choke at will.

Come to think of it, I think I owe ya a visit, I was talking about dropping in but never did, did I? :D

Check the choke break diaphragm. It should pull the choke off after just a few minutes.

Do you know how the choke break diaphragm work? I mean how the diaphragm get the vacuum in it to trigger the choke break after few minutes?

It has a constant vacuum.
