suppose to be 1/3 bottle in crank case. 1/3 in vacuum line, 1/3 in tank(half full roughly)
and if you put it in the vacuum line did you put 1/3 while running? once the 1/3 is in you shutoff the engine and let it sit for another 15 minutes or longer, then start it up!
if you put all of it in the gas tank with a full tank you wont see smoke.
I didnt want to put in in the crank case so i did 1/2 vacuum line 1/2 gas tank.
