I bought a jet kit but it didn’t fit my carb Can you link me one that will fit a pz30 and also I just took it out today and it won’t idle with the choke on but It used to idle just fine with the choke on when it was cold what can be causing this

You said you removed the carb. Make sure that the O-ring where the carb attaches to the intake didn't get pinched or left out. These mains should fit. https://www.amazon.com/gp/product/B0...0?ie=UTF8&th=1
Not sure what pilot jet yours takes as they are not the same from one manufacture to the other.

Thanks I’ll check that and I’ll order the Jets
