dear maruti 800 owner friends,
I have a 1993 maruti 800 (carbureted). Recently I had given my car to the MASS for the job of cleaning the carburetor. I was against it whereas my dad insisted we give the car to the MASS. I thought they would do a good job but as expected due to low/no talent at MASS for servicing carburetors I got it damaged and with improper running, mileage (15 kpl on highway) etc.
After receiving the car it was not running fine on petrol. As it is retrofitted with LPG I was using it as an LPG ONLY car. It was not idling fine. So out of frustration I myself removed the carburetor and cleaned it with carb cleaner. It did run fine for a couple of days and it was again back to square one.
Then again around three weeks ago I again removed the top of the carburetor and sprayed a good amount of carb cleaner through all the openings i could see from the top. From then on the car is running fine just as it used to run when it was new.
When i got it from MASS the idling Screw was 4.5 turns out from closed position. But now it is just 1 turn from closed position.
Buy I would like to ask you friends/enthusiasts, What is the ideal setting of the Fuel Adjustment Screw for the M800. I got a Ucal Mikuni carb.
N.B. At the present setting of 1 turn I am getting aroung 15 kmpl in the city. ODO reading is around 68000 km.

I saw your video. I think that due to non-running of your car their seems to be some carb problem. I request you to buy a carb cleaner spray, remove the air filter and spray in the carb throat till it is clean. Because the petrol in the carb bowl and the overall carb might have turned into gunk. Then take it for a good spin around town but do not overspeed. Let the car get warm naturally from normal running.
If this does not solve the problem then removing the carburetor and cleaning the whole carburetor seems to be next in order. But overhaul it from a known mechanic only or if any our forum members are willing please take help from them.
Do not give to MASS. Pls read my earlier post.
I would like to add photos of my damaged carburetor, Courtesy MASS, PUNE.
the missing timing window rubber grommet is a standard feature of MASS at every service
