19mm Arreche tunning.

Is their only one screw that adjusts the a/f mix and idle? Is it the same screw?
Thanks,

 

arc: there should be two 1 air/fuel mix 1 idle mix

 

I only see one. Can you get a pic and circle the a/f screw? The only one I see is the one that raises or lowers the slide...

 

There should be one with a spring which is the idle screw the other will be a small screw which is the air fuel mixture

 

Is the other screw inset and a flathead screw? It is flat to the carb?

 

The air fuel mixture screw is fairly flat to the carb you will be able to notice the difference between the 2. idle mix has a spring on the screw the air fuel mix does not

 

you do have to use a screw driver to turn it right? If I screw it in, it will richen the mix?

 

BTW< what should it be set at for a Corsa/r?

 

Yeah you have to use a flat head screw driver to adjust it. usually screwing it in will richen the mixture screwing it out will make the mixture leaner

 

THANKS! What do you think I should set it at?

 

Usually its all about trial an error as i've found out before. But try to get the engine running as fast as you can throttle wise with the air/fuel mixture screw. No one can tell you the right set up dead to the point if you no what i mean.

 

Thanks so much for the help! I am going out to the shed to check it out right now!

 

No worries mate

 

It was at 2 turns out, but I went to one turn and will run it in the morning.
Thanks!

 

You should adjust it when the engine is fairly warm rather than when its cold then you will be able to tell the difference

 

I will run it back out. Will I be able to "hear" a difference?
