I just got an old 78 CB400T that is not running. I pulled the carbs on it to clean them and while taking them apart noticed that the slot on the little screwed in piece inside the the right main jet (the Clymer calls this the main jet holder, though I don't know if that's true) is completely mangled, so I can't get it out.
I got the left one out (it's a vented brass screw maybe 3/4" long) and it looks fine. The question is do I need to remove the right one too (i.e. how much does this holder effect the carb performance) and if so, how can I get it out when there's nothing to grab on to? I have screw extractors but none of them are small enough to fit in the main jet hole and I would be afraid of ripping it up. Any ideas?
Upon review these may actually be the needle jets themselves. The Clymer is not very clear. Can't wait to get that factory manual!
