Ok, I'm using my car right now. (In garden). 0-3/4 throttle is fine, when i go full throttle the engine stutters and will eventually fail. I try leaning it (turning clockwise) It gets slightly better, if i go too far the car gets stuttery at low throttle and cuts out, before that point the car is still not perfect. When idling, the idle is quite high and the clutch is slipping, i turn trim lower and nothing happens, too low and the brakes apply. The idle is erratic it will have bursts of high revs then go low for a bit then randomly high again. PLEASE HELP!

Adjust your High Speed Needle first so it operates at full throttle properly, and then adjust your Low Speed Needle. The High Speed adjustment affects the low speed needle as well since it controls overall fuel delivery to the carb. The low Speed need just modifies the setting of the high speed needle for low RPM operation.

I just wanted to add to MOTO's post and say....
Make sure you go back to stock needle settings.
Only adjust in small 1/16 increments.
And last but not least be sure you keep an eye on your engine temps.

Ewwww the one adjustment carbs are a royal pain to tune from what I have heard.
