need a help, I bought a Golf with GF engine, pretty nice condition, low mileage, but from the first day I got it, it couldnt keep idle, and eats around 13-14L/100km.

Thanks for anything, Jacob

Start with the basics before swappin in unknowns.
Timing
Fuel
Air
Spark.
Lumpy running engines may just need a good tune up.
Validation of Grounds and Vacuum leaks go a long way in getting better mileage and a smoother running car.
Since it is a new to you car, a cap HV leads as well as a rotor may be warranted, I switched from Bosch triple and double plats to NGK plugs and there was a marked improvement in my cars….

BOSCH plugs…I got two bad sets in a row one set had 2 bad plugs, and the other had 2, as well as me fighting a bad spark wire… So I was fighting 3 cylinders misfiring after the new plugs, at one time, thankfully I have 2 cabby's and I swapped parts Cap wires and plugs to eliminate the issue. (Bosch) wires as well less than 2 months old… Real issue was that I had a bad spark wire, the new plug sets allowed me to increase the miss-fire from one cylinder to 2, then 3……
This is why Bosch is only one step up from Lucas in my book….Lucas may be the Lord of Darkness, but Bosch is his Prince. ( Run-ins with Lucas on my British Leyland in my youth 2 fuses on 2 of my cars, and the wires would protect the fuses at all times…

more updates… Some things solved, some not. After I throw in new set of spark plug cables, spark plugs, rebuild the distributor completely, and set the the advance timing, the electric part of the problem seems good. Then we started work on carburetor. At first, I found out that there was re-drilled nozzle with 2mm drill

The oil seperator is dome shaped, about 75mm in diameter with an outlet to connect a hose and is an interference fit in the back of the block, you have to lever it out with a screwdriver. If the hose that originally connected it to the air box is now run into an oil catch tank that is a bodge, if it were me I would buy and fit a new seperator.

Whole thing seems like there were some air "leakage" (sorry I don't know how to say it better in English) in suction path. So I resealed whole suction, then finally a mate with many old VW's did a complete rebuild of the carburetor (everything new, including shaft bearings, everything set up), I bought new fuel pump, new fuel lines, new vacuum hoses, everything double checked, valve clearance done, injection timing set up with stroboscope… And ques what? Nothing

Long story….
