I went through both carbs today and set all floats per Holley tech sheet except I set all of them 1/32 inch lower. Car runs fine but after a test drive I'm still getting wet primary throttle plates after about 10 minutes heat soak. Fuel bowls temp is under 120 deg F, engine in running about 180 F. I always open the hood after a drive.
Today I finally noticed some spitting and bubbles from the shooter nozzle so now I'm sure that's where the fuel is originating - the accelerator pump circuit. I tried to shoot the pump cover with my IR gun but of course it's pretty much out of sight down there. Best I could tell it was around 140 F.
Any ideas on how to stop this? I'm running a 1/4 inch composite insulation base gasket now and that is pretty much all I have room for. I guess I could wad up some aluminum foil and stick between the housing and the manifold but I'm hoping for something a little more elegant.
Also - here's a weird one. I grabbed my S&H air cleaner from the front carb and removed it and found the whole under side was covered in an oily substance. It was clear with a reddish tint and no odor. I removed the top and found the K&N air filter and the inside of the base coated with the same
oil. It's apparently leached out from the filter which are about a year old and only have a few hundred miles on them. The other one was OK. I guess they must have really soaked this one when they treated it.
