What is involved in tuning a Weber? What adjustments can be made, like mixture and idle?

I don't think mine needs much in the way of tweaking, but i'd like to have a fiddle and I am not sure where to make adjustments.

Well unless you change jets the only adjustment is the 2 idle mixture screws.
Note these work opposite to most cars, they are FUEL jets not air. Screwing them in makes it leaner at idle, and up to about 1/4 throttle.

I'll lend you a Weber tuning book if ya ask nice... :wink:

I saw the 2 idle mixture screws. Do you wind them in all the way and then back out evenly? or all the way out and back in?

In then back out, both should be the same.

It's a combination of getting the coal just the right colour and temp, but not too smokey. Best to do it in a well ventilated area - but not too windy.

when to put the meat on is key - some wait too long, others jump in too early. Use the splatter guard. Experts say not to turn the steak or chop too frequently. I have a gas one personally as I couldn't be bothered with hot coals. :D
