That's way too rich if your running a fixed jet (no rods).The general rule is to be 5 steps leaner than with a rod.You should be around 67 possibly leaner.Your float level at 1/2" is too low,it should be around 1/4 ".I would think at that level it would lean out due to lack of fuel in the bowl. It's hard to keep the needle on the seat when the fuel level is that low.A q-jet has a small fuel bowl to start with.When you build your fuel system you should have a pump with good volume and 1/2" lines to keep the bowl full.And keep your pressure low (6-6 1/2 lbs) for a clean leave. gsa612
