2003 F40 Smoking

I have a 2003 F40 that I had to end up soaking and cleaning really well. After re-starting it ran great but I noticed some white smoke that I don't usually see. It doesn't smell like oil burning or anything like that. Could it just be some of the left over carb cleaner? Also when I started it, one of the bowl drain screws was barely loose so a little gas leaked out, not sure if that had anything to do with it.

Any left over carb cleaner should burn off and clear up. Make sure not overfull of oil or has gas in oil. If doesn't clear up then have a compression and leak down test run on it.
