Stock carb jets

zackattack91 · 01-15-2017, 12:00 PM

Anybody know where to get a jet kit with the idle and main jets for the stock carbs that come on these ATVs. All the kits on Amazon and eBay say they are for mikuni carbs. Don't know if they will fit. Looks like I have a pz20 carb with the gold choke lever.

Also, my idle seems to be acting funny. I have an ROM meter attached to my ignition coil, and randomly while idling it just bogs and drops about 200 RpM for a second before going back to around 1600 rpm. Im geussing the idle jet could be dirty even though I only have about 6 hours on the engine. Being that I can't get in to the stock carb because it's basically riveted shut, I was going to get an aftermarket replacement that actually comes apart.

A NEW tunable carb saves u from hassle... Stock carb in these days had

stops ppl playing w/ them.
If u're lucky that can acess it, compare the pics in http://jetsrus.com/ (some PZ?? isn't a TRUE Keihin clone

) 1st. Once u know jet's type, u can find it in various places . Forget bargains from chinese sellers at this time, they're on holiday https://en.wikipedia.org/wiki/Chunyun

I just notched the 3 screws (what you call rivets) and unscrewed. No big deal, mine is quality Keihin Carb. Your results may vary.
