I have just finished a full restoration on a Honda NH125: bottom & top end, all bearings & seals changed.
I am updating the carb on this 125cc engine as the stock carb was buggered. I am putting in a clone PWK 21 which looks pretty well made. I totally disassembled the carb & cleaned all the passages and jets. The problem I am having is that the engine only runs properly with the choke circuit opened. Otherwise it dies like it is too lean. I have gone all the way down on the clip & am running the richest jet (150) to no avail. I don't seem to have any air leaks. What else could be causing it?
