Stihl 023 wont idle

[CameronStone05]

Hello,
I have an 023 that a friend gave me, it's a family heirloom... I've replaced the fuel line, filter, carb kit put into the OEM carb, breather valve(currently removed as I thought it was the issue) saw starts on choke, seems to run a bit high on half and runs in the on position, aslong as your giving it revs, but sometimes it just bogs down and dies and it will not idle apart from the odd time for 5 seconds then dies. I've tried adjusting the carb. I've checked the cylinder and piston for scoring both exhaust and carb side. And I just dont know what to do next. I've read similar forums and the only thing I can think of that I need to do is a p/vac test which I'd need to buy the tool which I'm not prepared to do for this one machine.
What else would you guys/gals try...
Thank you in advance,

given the age i would do the seals- doing 2 o26's right now and both get - got new seals needs them anyway most likely and the carb could be an issue- refreshing to see s smaller saw that isn't a clam shell- have a 023 in a box of parts

Thank you in advance,

You likely have an air leak somewhere or an internal carb problem (Zama main nozzle). Was the carb kit OEM? Did you set the metering lever height correctly?
