Aq 125 carb mixture screw?

[tonywayne]

Ok i am on the lake now and only have my phone to search where the mix screw is and how to adjust it and cant find anything. Can someone just explain to me where it is and how to adjust it. The boat runs ok but acts like it starvs a little for fuel between 1500 and 2000 rpm. Then at wot it runs at 4500 for a few secounts then rpm drops to 4000. I would just like to know where the mixture screw is so i can mess with it. Thanks.

It should be pretty easy to find. There are only two adjustment screws the idle (on the front right) and the mix (back left).

It's on the back left corner of the carb pointing towards the driver seat (screwed in from the rear) just above the intake manifold.

Usualy the air screw is for low speed operation.
Start with the fuel delivery system.
Fuel pump pressure.
Tank pick up.
Water in the fuel.
Tank vent.
