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....

Just to define: 'bottom out' means just touching. As you gently turn the screw in you will feel it touch. That's All! It's pretty easy to wedge the tapered needle into the port and deform it, you're seating steel screws in soft casting metal.
No (IMG:style_emoticons/default/smash.gif) Unless someone has honked down on the air bypass screws already, any leakage should be negligible; and the idle mixture screws just use the seat as a starting point for making your baseline setting Harvey |
