Cylinder compression check numbers and spark plug reading inconsistent idle

Funny how those spark plug wires being connected helps cures misses LOL. Good story.

8 turns out on the idle mix screw? Like 8 FULL turns? Some thing is sure messed up...did I just win the Captain Obvious award? The idle mix screw is almost falling out, and may be admitting air if that far out. So almost like there is way too much fuel (power piston up and the rods all the way up, float way off, needle/set damaged or filthy, float gas-logged and sinking) or the idle air jets are messup.

I would say more like 8 - 3/4 turns. Just from memory I got to the point where I was just turning as far as my fingers would let me. About the time I felt less tension on the spring is where it got better. Funny thing is that what started me down the path to a second, yes second chinese "Carter" was I was rebuilding my original and the idle mixture screw snapped off and I couldn't extract it. These chinese Carter clones are barely decent. Both of them had floats that leaked and sunk within 3 weeks of use. I got this one because it had more correct ECS ports. I've noticed while tuning (and this may be normal) that as I reduce the idle speed screw, it starts to whistle or whine as the throttle plate closes. At that point opening the idle mixture screws stops that whine. Seems to make sense to me as at idle it has to pull air from somewhere.

I'm looking for a better carb right now :BangHead:
