Congrats on it running,
If the smoke if not blue you are doing well,
if it hasn't run in months/years, it will take quite a while for all
the residue to burn off.{and stink}
Run it long enough to get warmed up, then check for leaks,do a
safety check head to toe{ya could have missed tightening something
or a cotter pin somewhere etc.} I have...better safe...
{see FAQ"s} checklists. and the always good, "oil change".
Enjoy it!!!!!!!
Hope it helps
