Heya guys,
I'm not that good with engines.
I'm hoping someone with more knowledge than me can help with an engine diagnosis problem I am having.
Bit of history: I recently purchased a 1200 ute with an A14 in it. I was hoping for a driving rebuild/project with this car but ran into issues the day I got it

One problem I was having was a flat spot when you depressed the accelerator so I took a look at the plunger and noticed it was worn, so I put a kit through the carby (standard carby). Taking the carby off I noticed that the choke (manual) was set to have the butterfly close…engaged all the time. Then I noticed that the throttle screw was out 7 full turns from seated. Got to thinking that was a whole heap of fuel going into the engine with minimal air just to drive it.
So while the carby was off, I decided to do a compression test and found that the #4 cylinder was lower than the rest. #1 – 155psi, #2 - 155psi, #3 – 150psi, #4 – 130psi. It was low but I figured that it was still ok to run.
I checked the static (no light yet, need to get one) ignition timing and it was like 15-18deg in advance… I put it back to factory ~8deg.
So I bolt on the carby and turn it over, it fires but now it is coughing big time with the dreaded bluish smoke. It does sound like it is running on 3 cylinders. Checked spark was getting to the plugs, plugs are sparking, cleaned and gap set.
I am at a loss,
1st: why is it now blowing smoke and farting like a howitzer when it wasn’t previous?
2nd: What could have been behind the thinking of so much fuel going in earlier?
3rd: Why so much advance in the ignition timing?
Can someone please point me in the right direction with this, I don’t have a great knowledge working with engines. I am resigned at this point to do a rebuild on this car, I haven’t even put 20km on it. Not that I payed much, but still.
Any assistance would be greatly appreciated.
Clay
