Somebody help a brother out......
Rebuilt my idf's but need a baseline for setting the Idle Air adjustment (the one with the nut) back to it's correct location. I have an initial setup of 1 1/2 turns from notes when they were re-jetted 3 years ago but since this screw does not bottom out like the Idle Air adjusters I need to know where those turns are from?? Is it from the back of screws being flush inside with the throat or the front of the screws bottomed out on the nut? Or something else entirely? Note to self to mark that kind of stuff in the future and to get that Weber book from Shoe. Oh wait I had someone else rebuild them.... (IMG:style_emoticons/default/dry.gif) Thanks in advance for replies... Ken |

Ken,
The idle air adjusters are the ones with the jam nut. They're used to match all 4 carb throats to the one with the highest air flow. Start with them all closed and only open them to match flow with a snail (or a really good ear for the sound of rushing air). The mixture screws are the spring loaded ones. |
