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?

Clean the jets again and get a air box or air filter pods on and fine tune from there. If you are turning the screw all the way in it is richening the mix and with the air box off you are all ready getting to much air with the screw 1 turn out so it is making it lean so when you turn the screw in to match fuel to air. So get the air box or filter pods on and go form there.

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?
