What I meant by starts easily in the cold, was that I have to use the choke, and fully, but it starts easily. I push the choke in as it warms up. If I go off the choke immediately after starting, it'll die.
Yeah, that's how I adjust the carbs - pin up - adjust alternat carb.- speed drops off 100-150(?) rpm. Get them both even. I'm a pro at this part. (I'm on my second unisyn in 30 years) Now, I guess I tended toward lean, because with tight carbs/engine, you can lean it out so that speed drops but it doesn't die, and that ends up being too lean when driving. 1-1/2 to 2 flats down (richer), it still drops, but dosesn't starve when you put your foot in it.
Float level may be the issue though I was pretty careful setting that (a stack of feeler gauges), but it may still be too high. There's an earlier and later, and maybe even later spec. I think mine's set right.
As far as timing, for this block/E head and D cam, 10 is the spec, just that I'm using carbs instead of FI.
Weather permitting I'm going to recheck all this over the weekend.
Right now, seems like float level could be the culprit. If it's too high, then it seems that there'd always be an excess of gas available, no? Lowering the float until the engine seems starved (all else staying the same) might be be the ticket. It's just a hassle to keep pulling the float bowl covers and tweaking the stainless strip on the plastic float.
Just realized that maybe grose jets (float valves) probably mess with the fuel level, not because it's not shutting off at the same level, but because of the nature of how the valve actuates. I should probably go back to regular float valves first.
