Fuel mixture going down [SOLVED]

[VaesareN]

Am i really bad at cars or why is my fuel mixture going from 15.8 to like 12.9 on a trip from the hosue to the store?

In older updates it used to rise from set to 14 to like 16...

If you dont use the choke, the engine will coldstart pretty lean. When it heats ut, the AFR should reduce itself. You should also tune the carb so it says 14.7 when its heated up. Use the choke, to lower the AFR whith a cold engine for better performance and faster heatup.

Wait eeeh...

I have tuned my carb to 15.8 cuz when i'm driving it gets down .1 evenly and when ive driven from the house to the store it's down at 12.9.

And when tuning the carb it jumping from 14 to 15 and then down to 13 and so on.

Its moving at idle, thats normal, its fluctuating. tune it so when youre driving on normal engine temp, its on 14.7. thats the most optimal.

solution!: as your engine warms up to 100 degree the air-fuel-ratio decreases
