Maybe if you gave people time and we could read what you typed/said, someone may be able to help you.

A clymers manual will tell you all the information you need.

There is no "washer" for the air/fuel screw (you are talking about the upsidedown slotted one right? ) you have to play with it n run plug chops till you feel its right, in =richer out=leaner...hope this helps...if its the same screw where talkin bout here..lol

[downlowcc]

its on the bottom of the carbon the edge in the middle ,lolnot the one to drain the bowl

[bigredhead]

go to www.partsfish.com and look up the diagrams for the carb.. easy to do.

I'll check my manual in about 20 minutes. yeah it's the air/fuel screw .. i beleive it has the spring and that wather on top so the spring does not dig into the carb body .... be back in a few.

[bigredhead]

ok specs for ATC 200.. plain 200..

Model:PD 35C
Main Jet No. 105
Initial pilot screw opening 81 - 2 turns out.. 82 - 2 1/8.... and 83 1 1/4 TURNS OUT !!
Needle Jet/Clip : 2nd gove
Float Level : 0.49 in ( 12.5mm)
Idle Speed: 1400 RPM + - 100


The pilot screw assembly should be

Bolt ... then put the spring on.... then the Flat Washer.. and then the RUBBER O-RING

then put all this into the carb... Turn all the way in until it seats.. don't overdo it as you don't want to crush the o-ring also make sure the old one is not still in there... or you will have problems.

Once you feel it bottom out slightly.. then turn 1 1/4 turns for the 83 and it should fire right up and you can adjust it after it's on the bike.

[downlowcc]

lol so the washer goes into the carb the put the spring in the carb the the bolt o ring ??????

[bigredhead]

picture the carb in your left hand....

with the right hand.. put in the

0-ring first.

Then the Flat metal washer

Then the spring

Then the nut.

[downlowcc]

* the the man 1 more lol then ready to start. the side screw it has a spring visible any suggestion ?

[downlowcc]

it is screw set b thats what the carb diagram says it is

[bigredhead]

That's the idle screw.

In all the way and then out 2 turns for starters... IN will make it idle faster..

OUT will slow down the idle.

[bigredhead]

And 1/8th turns make a difference.. don't turn it in out in out.. like a mad man when you first start the engine... if it starts and rev's wayyyy high.. hit the kill switch and think it over...

[bigredhead]

And don't go crazy when you turn in it all the way.. it pushes against the plunger in the carb lifting it when you screw in... you don't want to dent the plunger / slide.

[downlowcc]

man bigred head thanks alot got her all together and put the tank on turned it to run and choke on and pulled .....nothing lol and pulled again nothing then opened the tank lol :o pulled again ...nothing pulled it again SHE FIRED :beer :beer BUT THE ONLY THING WAS THE THROTTLE WAS STUCK WIDE OPEN (GOOD THING IT WAS IN NEUTRAL)SHE SCREAMED LOUDDDDDD PLAYED WITH THE THROTTLE WHEN I NOTICED IT WAS NOT REALSEING I FORGET HOW SHE SHUT OFF LOL MAN THANKS TO EVER INPUT AND BIG THANKS TO BIGREDHEAD......

[bigredhead]

Cool... good ot know you got it going.. i know how you feel... it drives me nuts when i'm so close to having something working but minor details prevent me from getting it done... LOL..

Your welcome.

The throttle stuck wide open.. i bet that's simply the slide in the wrong way.

When you unscrew the cap from the top of the carb ( where the throttle cable goes in ) the round thing only goes in one way .. or it's wide open !!!!

check that first !!

[downlowcc]

yesss went for the first ride (bigredhead) was great lol does not want to idle though it wants to stall i played with the one on the side it makes it rev real high when i hit the gas ????? and is it easy to tightin the chain thanks in advanced

[bigredhead]

What's the spark plug tip look like ? if white/gray .. too much air not enough fuel.

Black means too much gas.

check and report.

[downlowcc]

its black very black i set the side screw idle screw back to normal screw it in an back it out 1 1/4 turns that how it is now.

[bigredhead]

the 1 and 1/4 turn is not the side screw.. it's the vertical one between the carb and airbox.... the one with the flat washer.. and rubber o-ring..

[bigredhead]

The idle screw does not have a setting specific to it... but 2 turns out should be somewhat close ( if it's in the manual.. i did not find it ! )

The idle screw is the horizontal one. with the spring showing.



edited to add :.. the vertical screw.. with the ruber o-ring flat wather.. .. . . . is the one that needs to be set to 1 1/4 out... it determines the air to fuel mixture.

[bigredhead]

oh and by the way.. make sure you are not leaving the chole on... UP for off i beleive.

[downlowcc]

so if its black the should i turn the 1 1/4 screw?in for more air ?

[downlowcc]

when i put the lever up the flap in the carb closes that choke right the the second position is half close the third is all the way open

[bigredhead]

Well.. the air/fuel screw should be ajusted as follows.

With the engine fully warmed up.. you slowly turn the screw in until the engine starts to sputter.. then turns it out until it sputters again.. and then figure out the middle mark.. that's where it should be.

Depending on your elevation and temps etc...... not all machines will have the exact same position .

These adjustments should be performed with a CLEAN air filter .. installed WITH THE COVER ON.

You can also check your choke position by removing the air filter.. stick your finger in there and play with the choke lever... make sure it's working and not stuck.
