CB750 Carb Questions

[boostaholic]

So I have my carbs pulled apart right now on my 80' cb750k. Bike was running bad at idle, had to have the mixture screws all the way out to idle. Decided to pull the press in slow jets out and ended up destroying them. First, where the heck can I find these things? Second, what else should I do while i'm in there? I have cleaned them a few times already, but haven't done the slow jets until now. Do the needle jets need to be adjusted from the top side of the carbs ( I looked at them but am unsure of how to adjust them if the even can be adjusted).

Appreciate the help.

I will update my own post. To me it looks like the 77-78 press in slow jets are the same as mine. Can anyone confirm?

I guess if noone knows ill just have to measure em.

Can't help you with sizes, but a heads up on the passages from the back side if those jets to the throttle body.
They are very small.  Make sure you get air or fuel flow to where the gas dumps into the airstream of the carb.
A small guitar string poked in there from both ends, high, high air pressure multiple times helped me.

Would suck to install new jets only to find the passages behind them were the culprit all along.
