i dont know i this is a problem but in the morning when i start my car a little smoke comes out of my exhust. worming up right that is what i thought but. when i start it in the middle of the day it smoke to but is not alot of smoke and it is just when i start it and that is it it doesn't smoke any more i was just woundering if it is a problem. i dont want to put to much money into this engine because i am planing on puting an H22A in it.
