probably too rich.

hi idle when cold is good.

drive it with the oil cap off.
you can remove the air filter and pull down on the sensor plate at idle to lean it out. if it idles better it is too rich.

if at idle, it starts to surge it is too rich.


invest in a set of pressure gauges.

one other thing. you may have 2 vacuum hoses going to the warm up regulator(WUR). one should have vacuum on it at idle. if not that will make it run rich too.
