Full Version: No use, is abuse
I have concluded that I have a clogged jet, have added stablizer to fuel. What are the chances of clearing this snot from the carb with carb cleaner? I have a book on Weber Carbs, but I am in not hurry to spread parts out! 44 IDF carbs on 2L eng, ran great a yr ago! If I do need to pull carb, do I need a full rebuild kit? From where? razorbobsr@aol.com

Just take out the jets and blow them out with air or carb cleaner. A clogged yet does not warrant a rebuild ...
44's seem a bit large for a 2.0L

Pull the idle jets. Use a magnifying glass to see if they are clogged. If they are, you can clean them out by just blowing into them. If that doesn't work, use compressed air. Always check the easiest thing first when troubleshooting. IMHO, the idle jets are the easiest thing to check and they can be checked without taking the carbs. apart or even removing them. Be careful not to lose the tiny "O" ring when removing the jets. I carry spare "O" rings in my travel tool box. If the engine accelerates OK but runs rough when you let off the gas to run at a constant speed, it's probably the idle jets. I'm not exactly a Weber expert but I've had this problem in the past. Hope this helps.

Mine acts the same way, haven't gotten around to removing/cleaning the jets yet

Why would a clogged idle jet make constant speed/rpm miss-fires? Bob
If your down for the winter...call Art Thraen.

The idle circuit is responsible for most of the fuel at light/moderate throttle.
These guys also sell a device called the "jet doctor" that helps keep dirt out of the idle jets. You can also get the "O" rings from them or just about anyone who sells Weber carb. stuff. 44 idf carbs are not too big for a 2.0. You can change the size of the venturies, the air, main and idle jets to a combination that works for you. It may take some experimenting but all those parts aren't too expensive and are easy to change without removing the carbs from the car.
