i've been having problems with my 1984 honda big red 200, we never got the owners manual when we bought it, so i do not know the original settings of the screw that changes the amount of gas it gets. my dad accidently played around with it and now it won't start does anyone know the original setting of that screw???

 

Two turns out from lightly seated should get it started. Then after it warms up, and is idleing, slowly turn the screw in , and then out. Youre looking for the spot that has the highest idle, then go about 1/4 to 1/8 turn richer (turn it out), from that spot.
