The Crusher

I run dual dgv webbers on my 240z. It has a 280 motor and runs great. Motor size not a problem. With webbers they need to be tuned and ajusted. They will work and maybe even idle OK right out of the box, but you must tune them. Lots of info on how to do this all over the web. It sounds like maybe your idle circut might need some adjustment to start with. You may or may not need to re-jet, but you wont know until you get the idle circut right. You will also need some syncro meters to make them work together as one, this is very important. Doing it by eye is not good enough. Also, you should be able to get the jets from alot of places, hard to belive they would be on back order. Anyway, good luck. Richard B.
