77 polaris 340 colt ss air screw

[peter p]

My 340 colt has no carb filters.
I have the air screw at 1 turn out.

If I give it full throttle from idle, it bogs for a second like its getting too much air then finally goes.
This is with the engine at idle and the track off the ground.

If I fully close the air screw this doesn't happen and it's responsive right away. No bogging whatsoever.

Is it ok to have the air screw turned all the way in?

it should be at least a turn out...have you cleaned the carb (carbs)

I have everything running fine and took it for ride.
Everything was ok until the sled became sluggish.
I opened the engine cover and noticed fuel was leaking out of a hole in the side of one carb.
I attached a picture showing the hole where the fuel is leaking from.
Anyone know why it leaks from here?

sounds like the float is not adjusted correctly and putting fuel out the vent...

Needle and seat?

I'm setting up the carbs now but I think my slides are going to high at full throttle.
Does anyone know if the slides are to go all the way to the top or just stop as soon as they pass the top of the venturi?

yes just as it passes the opening.....
