Default 86 Ford Laser Cutting Out

Guys have an auto ford laser 86, carby, no ps, ac, i think its KC model.
hatchback 1.6L.

When car is cold you can be driving it cuts out.
Smells really bad of fuel
only getting 300kms per tank if im lucky. sometimes 250kms
When you accelerate in cold you can sometimes here the choke butterfly click.
No matter warm or cold i pull up to lights i have to chuck in neuteral otherwise car puts puts and almost cuts out. In neuteral its has smoother revs.

Timing has been checked
Last time i did service i put some carby cleaner.

Do i need a new carby?
Is there any how to guides on how to replace?

You wont need a new car just yet, but this one may be tired an need a reco. Is it blowing black smoke? Check the air filter too. Not alot of things to go wrong with these little beauties.

no only when cold but that could just be the cold right now as its parked outside.
Air filter is fine. I do a service every 10k and it was replaced a couple of months ago.
I suspect its a carby.

instead of wasting money on getting someone to reco, how hard out of 10 is it to just get one from a wrecker and swap it?

Not hard at all, you just take off the old one and connect up the new one, BUT you could run into the same problem as with this one. Have you tried tuning the carby? Idle speed, air flow etc.

Not 100% on this but there should be 2 screws on the carby that should screw in and out and should change the way the car runs. Unfortunately carbys are abit before my time and everything I saw in the workshop was mainly EFI. Some come with mixer screws, some don't just check all the vacuum hoses going to or from the carby too to make sure they aren't cracked. This will make it run poo too.

Couldnt see any cracks. All hoses fastened
But heres something
The 1st cylinder is not working. I replaced the spark plug and no difference. I see spark from dizzy to lead and lead to plug. What could be the issue?
Theres alot of smell of fuel and car does not run good on idle.
I adjusted the idle screw and it made a slight difference but still cuts out. If you stick it in Drive or Reverse it just cuts out a after a few seconds. No acceleration. If you drive and then stop it cuts out.

Could it be the fuel mixture screw. I need to get the 1st cylinder running 1st before adjusting anything i guess?

Yeah you need to figure out why number 1 cylinder isn't firing... Has the timing been checked?
