You are very welcome. That guy's videos are pretty great, especially for the DYI person. He does a video of completely reassembling a CBR, I think an f3 using time lapse. Pretty cool.
Good luck to you. Give out a shout if you get stuck.

I do not have to do a carb sync after cleaning them correct? When would that be needed?

Generally speaking the carbs need to be synced when one of three things have happened.
1. You've performed any type of valve work.
2. You have new parts in any or all of the carbs.
3. You've physically separated the carbs themselves.
There may be other reasons, but those are the big ones. General cleaning doesn't require syncing, (assuming they were already in sync) as long as you keep the parts you remove with their original carb. Four labeled glass jars are good for keeping things separated.
Above all, never ever, under any circumstance confuse in sync with NSYNC. One is great for your carbs, the other is terrible for your ears.

Perfect!

Good tip on NSYNC... wouldn't want to make that mistake!

Finished my "re-clean" of the carbs. I did notice 2 jets that weren't completely cleaned out. I went through all the passages as well. Just have a question.

On this pic, I tried to spray carb cleaner through this passage (circled) but it seems sealed. It is the same on all 4 carbs. Is this correct?


And the same on this one (circled)...

That is the fuel pickup tube for the enrichment circuit (choke). It should be clear. You can't remove it though.

Ok. None of them are clear. Suggestion on clearing them? Wire?

Wire and carb cleaner. Also, I don't think this will make a difference but open up one of the enrichment needles and see.if you can get air through it then. Very far chanced but it may be functioning properly and the needle is blocking the passageway. I highly doubt it, but its worth a shot. If not, it's cleaning time.

bpifer15, first thing is excellent photos, really well done. Now, to get the carburetors working properly you're going to have to split them apart and soak the individual bodies with all the other parts removed. I know it sounds scary but it's not really. Before doing so, make some really good observations on the operation of the throttle and butterfly. Notice that when the throttle is closed, the brass butterfly pretty much seals the throat of the carburetor. This would be looking at it from the engine side. Also notice that as you open the throttle, each brass plate butterfly opens the same amount. Operate the throttle while watching it move open and closed. You can also notice that the butterflies are actually kept in sync by springs located between the carburetors where each of the throttle linkages push on each other. The idea after putting it all back together is that for the most part, the brass plates open and close at the same time. If they look like they are, then they are close enough for the engine to start and run. What part of the country are you in?

This is the end you'd be looking in. (disregard the red circle and number)
