The engine dieing as you increase throttle is usually a mix problem, probably the low end. As you look at the end of the HS and LS needles, turning them clockwise leans the mix. Set the high end first. Go to full throttle and briefly pinch the fuel line. If the engine dies immediately, it's too lean. If it runs a while, then dies, it's too rich. If it speeds up briefly, then dies, it's right. Adjust the low end so when the throttle is increased, it is smooth. The idle needle is adjusted in SMALL increments, about 1/8 turn at a time.
