Default Bluish/blackish smoke

Well i'm wondering.. Is it possible to run so rich you'll smoke a bit of blue/black smoke.. my eyes are BURNING out of my skull from being in the shop 5 minutes. Just re did the head gasket and had the head leveled. and did a valve lash adjustment and timed it* should be on.. maybe 1-2 teeth off* Car had a blown head gasket in febuary 09.. just fixed it.. Maybe all the fuel that was dumped in it from trying to get it going with a busted dizzy is burning off?

It's 1989 civic with a d15b2 in it.. DPFI.. Please help before i need glass's!

Should have done a complete gasket change from the bottom/up. If your eyes are burning bad, check if you have an exhaust leak!

Negative, if your eyes are burning it is because it is running LEAN. You most likely have it too advanced and it is running HOT.

Okay.. pulled the spark plugs today.. they were CHALK BLACK!!!!..

Compression from left to right

120-120-120-142

Could my rings have gotten washed with all the gas that was in there.. i found gas in the oil and changed it.

Update

Just took it out for another run

132-132-133-144

I'm thinking the rings got washed! any suggestions?

Yes, this is a high possibility. Pull your head off and look at the cylinder walls. Either that, or pull the oil pan and look at them.
