Dellorto DRLA 40's, Won't idle. Options

[mmichalik]

My '74 has a set of Dellorto's on it. The car won't idle, I can rev it up and it will run but, once I take my foot off the gas, it dies.
I want to clean out the carbs, because I understand that crap will get stuck in the jets and needles and such.
Does anyone have any down and dirty advice: Do this, then this, type stuff, to clean them out? I just watched https://www.youtube.com/watch?v=8pDgxauguRY and will do that but, just wondering if there's anything else.
I have a rebuild kit but I'm not sure I want to do that this weekend but, I can if that's the best way to go.
Thanks!
Mike

If cleaning out the idle jets doesn't take care of the problem get yourself a gallon of carb cleaner and soak the carb bodies for a while. Don't need to take apart the acceleration circuit parts, then rinse out then with hot water, then blow dry, should clean them good. worked for me, see my post on the same issue

I will do that, if needed. Thanks!
Looks like one of the main jets had some water corrosion on it though..... Not sure where it's coming from, it rarely rains in San Diego and the rain tray is on and the air cleaners are always on the carbs. I'm hoping that it's not systemic.

Water in IMO is about the worst thing that can get into a carb cast alloy and brass suffer badly, ask me how I know ? ,had my RH carb apart to sort an unrelated issue and had the top cover off, covered it but that leaked and got water in one of the bowls !!!!!! my fault (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif) .
My carbs aren't IDF but water will do the same damage regardless.
I think the water has got further into your idle curcuit ,I reckon you need to give them a very good cleaning ,a bad main jet wouldn't be the cause of a no idle situation ,good luck.
