<VV> Hot starting advice

[chuck mckinley]

The car typically sits the order of 10-15 minutes (and stays hot.) I
only have to crank the engine for one second or less, just a couple
turns of the starter - as I say, it's really no big deal. It's just that
it starts with a big load of gas from the accelerator pump, so it starts
up with high rpm and makes me look like some kind of high-school Harry
in the parking lot! The choke has definitely come off by the time this
is happening. I guess I mis-stated the item about the unloader. I just
put in new plugs (NGK) gapped to .035 per instructions. I do not have
insulators under the carbs, just the thin gaskets that came with the
rebuild kits. I had the thick insulators on the car prior to the carb
rebuild, but they pretty much fell apart when I pulled the carbs, as
they'd been there for about six years. I got the rebuild kits from a
FLAPS, not Clark's, else I would have ordered the insulators. If they're
considered crucial I'll get a pair.
