Go to the beginners forum and do a search for tuning engines. That should get you started on the right path.

You can ruin that engine by running it TOO RICH for too long. It's an ABC engine and it needs to get heated up in order to properly break in.

Here's the quick and dirty way to tune it:
Get a tachometer
Run it full throttle and lean it slowly a few clicks at a time untill it stops gaining RPM. When it starts too loose RPM-- you've gone too far. Back it up rich again and then richen it up about 5 or 6 clicks on the rich side.

You will be able to hear it when it gets fully lean at top RPM. As you lean the needle it will gain RPM and then when you get too lean it will slow down again or die. Thats whats called MAX LEAN.

Find your max lean setting and then back it up rich about 5 or 6 clicks. That should do it.
