hi i have a stock carb from a PK-80cc limited engine kit and i accidently upped the size with a #60 drill bit, so i orders these, just wondering if anyone thinks they will work with this carb

What thread size are they?

If they will fit the carb then I think they will work ok the threads size on the jet and the jet dia might be right I don't know just looking at them. You could solder your jet shut and re drill it yourself I use a 0.027 dia drill in a hand held pin vice to drill mine. I use a propane torch and acid flux solder you can use resin core solder as well its pretty easy to do and don't take but a few seconds to do. The jets aren't cheap I see.

hi i cant drill or solder them due to the fact that i dont have any drill bits that small, and to get one i have to wait a month for the company to get them in, and the machine shop in my toen only goes down to a #66 drill bit, also it would be cheaper for me to get these in any cause, so either way im stuck. also im getting an email from the dealer about the jets and getting the standard size of them.

In general I see 5mm THREAD and 6mm THREAD jets.

The stock Chinese carb takes the smaller 5mm THREAD JETS.

Like zeeze: Main Jets 5mm : Dellorto Carburetors, And parts for you.

Those screw right in and work as an OEM replacement? No hassle?
