From a lightly seated position, turn the screw counterclockwise 1 & 1/2 turns. Go from there to get best idle adjustment.

The OEM manual for my 84 9.9 says to back it off 1 turn.

so ive got it at 1.5 turns out and it does need some love, so by the sounds of it i should start screwing in a lil. it seems to only start at full throttle nearly in neutral.and then run pretty good i guess but the only way to keep it going is to grab the throttle linkage and give it more gas.

There is no 'magic' setting. Whatever the book says is only a start point. It must be adjusted for correct running.

If adjusting doesn't work then it's a dirty carb.

Re: lean/rich screw stock settings from seated position anyone?

so ive got other issue now to say the least. i pull the needle all the way out to inspect it and the tip has broken off inside the metering chamber i guess. its way in there and no way to get it out.the only option i can see is where the manufacturer would have made an acess point to drill the 3 metering hole for the low speed.ive tried with compressed air and its sitting in a solution of diesel to try to get it loosened up.but if i have to remove the plug so to say that manufacturer put in to cover up where they had drilled im worried it wont seal and might alter jet result later.idk any advice.

there should be an access plug in it.like a small freeze plug,to get to the end of the needle tip area ,, carb kits usually come with new ones to put back in

what im seeing in the way of a plug looks to be about 10 mm plug made out of whats looks like its made of silver solder just a bout this sound right.i guess the only way to dig it out would be with a pick or something.

I think the needle is supposed to be flat on the end. Are you sure it's broke?

Needle comes to a sharp point on this carb. Remove the top welch plug and try blowing it back out the passage with compressed air, 125 psi should work.
