I don't normally leave reviews, but this will save some of you bunch effort,time and $$. I recently purchased a knock off pwk 38carb and it had blank Jets,plastic idle screw and a needle with no marks either. Spare Jets and needles were blank also. The cost was $40,so you get what you pay for. After several upgrades, real Jets,real idle screw, real needle, cleaned out mfg debris,..it ran ok but was hard to start and erratic idle once tuned!! Tracked down to a cracked cheaply made choke assembly,which they sent a replacement for fast. So it now idles and ran good now,especially for $40 +20 more for upgrades. It still was very lean in the midrange,even with a huge 180main,and the needle clip on the lowest notch!! I would pop and blow 2 ft flames out the tailpipe each time it decelerated..that wasn't normalI upgraded to the niici carb to just try it because it had the extra adjustable main jet(which my own 1997 cr250 carb had an electric solenoid version of stock) ..I can tell you theres a huge and immediate nite and day difference in the knock off pwk 38 and the nicci. Huge improvement with instant throttle response..idle mixture and speed set in 30 seconds ,,not 30min!!! Only top materials like red billet throttle slide cap and bowl drain ,,the slide was much tighter tolerance,,the idle was much lower and stable. Would buy again in an instant,,well worth the money. If you know how to tune dirt Bike carbs , had a beater of bike worth only $400,the $40 pwk knockoff will work fine.. but if your want a top quality carb that's easy to tune.,,the nicci is a bargain,,,at half the price of a 20yr old pwk38 selling for on fleabay
