Yes I have the idle set at about 700rpms. If I set the idle say at 900rpm or higher ( which is way to high)it does not idle down to almost a stall when I step on the accelerator and then let off, it stays at 900 rpm. In my first post I mentioned that when I let off the accelerator it idles down to almost a stall and takes reving it up a bit a number of times before it gets back to a normal idle. I was just out again and tried it and was able to get it to return to regular idle speed by just slowly increasing rpms a couple time. I tried setting the carb again....I had mixture screws out about 1 1/2 turns. I cranked idle back so it was idling really slow and tried adjusting mixture screws. One screw I was able to turn in all the way and did not stall engine or really changed idle at all. This is a brand new carb and I talked to the company I bought it from and they said they've never had a problem with these carbs right out of the box. I see nothing wrong with the linkage throttle shafts etc. I am going to try tuning with vacuum gauge to see what happens.
