Carby Idle Speed Screw?

[DearmanKE]

Hi all,

my 3tc in my t18 is not idleing properly,

it will start and then to keep it running i have to revv it, if i don't rev it it the revs will drop down below 1000 then it will die or it will stutter and jump back up to 1200 or so then drop down and die, sumtimes it keeps jumping up from 200- 1200 a couple of times before it dies.

 

this started happenijng yesturday on my way to a mates house, i was almost there so i jsut used the handbrake when comeing to a stop and reved as i was doing so, when i got to my mates i popped the hood and found the lid of my aircleaner(which was a homemade carboard one had come off, so i simply thought oh it was just breathing in to much air and popped the stock lid back on(it was on my backseat and went inside)

when i came out a few hours later i expected it to be ok and idle fine, but it was doing the same thing, so the aircleaner must have been ireelevent.

today i took the aircleaner off, and i got it idleing (by adjusting the screw in the picture that only has one thing circled), but i think this is the choke or a mixture screw? because when i rev it it revs and hangs for ages then drops back down(also with this screw i got it idleing high like 2.5k or sumthin, so this I'm guessing isnt the idle,

 

can anyoine identify the idle screw out of the ones circled, or can anyone see where the idle screw is if i have missed a screw?

 

or if anyone has a theory of what my problem is/might be feel free to share

If I were you Id find a good carby tuner and get him to put it right. Then just get it checked once in a while. He may be able to explain the details to you and show you how to tune it. You could also buy a manual which covers the motor and carb, assuming its the stock carb.
