It's your slipper. Turn the nut in 1/4 of a turn until it improves.

I had the same problem out of the box, in my case it wasn’t change into second gear.

But I have already turn it in 3/4 till the spring is compress.....should I keep turn it in until the engine running better or is there anything else I need to adjust????

sometimes the plastic clutch shoes will freeze to the fly wheel......should come loose with a few short bursts...if not I would look at the shoes.

Or maybe the clutch is really bad and it won't engage fast enough/not engaging fully.
