Thea has 68,000 miles, and generally runs well. Cold starting, however, is an issue, as it's always flooded, even after a week of not driving. Why do I know it's flooded? because if you don't hold the throttle at least 1/2 open, or god forbid, pump the gas, it'll be a while before she finally fires and belches black smoke. Even so, it takes a few moments for all cylinders to fire and there is still some black smoke. Once she's cleared her throat, she runs perfect. Plugs are clean, too.
First, it's not the choke, as I've left it blocked open and on even chilly mornings, it did the same thing.
While a kit is a reasonable start, what areas should I pay special attention to?
