That's good to know...maybe it could be a light greyish smoke....that would indicate a light richness of gas....I'll know more after a few more tests...THANKS for the help and advice.

Blazer runs good now....still smoke at start up....and when revved up.....believe it's going to be valves....no oil on the plugs....thinking of rebuilding the heads and adding dual exhaust....will post pics soon. Thanks again, CK5 family, for the help.
