No one will ever be able to answer you questions with so little information. So far we know its a .46 and made in china. That takes in a hugh variety.

What brand or marking are displayed on the side?

Is it a four or two stroke?

Is it a bleeder carb (important question)?

Or is it a double needle carb (important question)?


Concerning chinese engines, there are many fine engines produced there however there are just as many klinkers. This almost always is caused by poor quality control and inconsistancy.

Also please note it is unlikely that a main needle one and one half turns out is a good starting point for an engine of that displacement. That is a very lean start setting.

If you can,t answer any of the above questions the you will need to post photos of both sides and that way you may get plenty of good information.
