- This article is about the stock carburator. For other carburators, see Carburator (disambiguation).
The carburator (
: Kaasutin) is a part for the Satsuma which can be found in the garage at home. It is attached to the cylinder head with 4x8mm bolts. The stock carburator has a separate airfilter that is attached with 2x6mm bolts.
The purpose of a carburator is to mix air and fuel to make the engine powerful and efficient, therefore making it one of the most important parts of the engine.
If the stock carburator is used without having the airfilter installed, dirt will accumulate in the carburator. This will make the engine response worse and hamper performance, and can randomly cause the throttle to get stuck open. A dirty carburator can be repaired at Fleetari by purchasing the Engine adjustment or Motor tuning service.
Despite being a single-barrel carburator, it is less fuel efficient than the racing carburators and twin carburators, because of the game's simplified fuel consumption calculation (throttle position * RPM). Since it takes more throttle and higher RPMs to get up to the desired speed, it will consume more fuel than something more powerful.
It can't be painted with the spray cans, it can't be damaged, and is it only passes inspection if its air/fuel ratio is between 14.05 and 16.0.
Stock carburator AFR table
The fuel mixture can be adjusted by turning the mixture screw on top of the carburator with a screwdriver; scrolling down makes the mixture richer and scrolling up makes the mixture leaner. To set carburator to an acceptable (internal) AFR of about 14.4 (Around 14.7 in-game at mid temp), scroll down 44 times (which resets carburator from any position to 10 AFR) and scroll up 22 times (One click of the screw is about 0.2 AFR). See chart for more info
Internal AFR defines in-game AFR under "ideal conditions" (at high temp), real AFR changes with temperature a lot, so at 14.6 AFR internal, I[1] measured 14.9 at middle temperature, at speed. Labels on the chart are placed, as if in-game=internal, so adjust accordingly.

Notes[]
- Throttle lever (the golden part of the carburator) can be used to artificially rev the engine, it can be useful when trying to fix problems with the engine without having to go back and forth to rev the engine in the car.
- Not bolting the carburator down fully may cause the car to catch on fire.
- Chart was done from bottom position (10 AFR), values might be shifted, when doing it from the top (22 AFR) position.
Trivia[]
- In the 29.05.2020 update, the Carburator behavior was adjusted in regard to the fuel pump. This means that a worn fuel pump will cause a cold start which will make the car take longer to start.
