If you replace your carbs let my know what you want for the old ones? Just don't lose any parts.
Simple if some one else can, why can't I

I feel for you, as I also am in college. However I find it much easier then High School.
If you can't find good boots, your bike will never run right. So the solution would be to switch carbs. You could just do a search on e-bay for "70-76 CB 750 Carbs." Just swap out the boots, and they bolt right on.

maybe take a breather, step back for a bit.

the one carb, the one overflowing.
try taking the float bowl off,
hook it back up to the tank with some gas in it,
and turn the petcock on.

gas should stream out aroud the float valve.
gently lift the float itself till it stops and seats the float valve.

the gas flow should stop.

if it doesn't, you gotta find out why.
a scratch in the tip of the float valve.
a scratch or worn valve seat, or a piece of grit jammed in there.

look at one of the others that do stop the flow, real close.
anything different?  missing a spring or something?

i'd then check the float for boyancy (sp?)

then for float level.  bend the tab that pushes the float valve in just a bit
to push the valve in  sooner.

hang in there guy............

Re: Honda cb 750A Carb problem

OK so heres the thing. Beofre when I didn't know what I was doing I betn the wrong tab oin the floats, I bent the tab that the valve sits on. So I just went back and bent it where it should have been. The bowl seems to fill full of gas with no problem. But now my bike wont turn over and I got rush build up in my tank. Wil clean the rust BUT THE RUST IS NOT THE PROBLEM so don't be like OH WELL THAT SOLVES IT rust is in your tank. There was no rust before, something I did recently and got flash rust.

So just waiting for bike to settle to try to get it to turn over. Plus the leak stopped after I bent the tab back. Step pops said to reset the tabs if I cant get bike turned over. Guy had them at like 27 ive got them at 13. Plus he said I could just go buy some hose for engines from pepboys and put them on. ARGHHHH, because this is ARHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!.

Thank you Motogradv because I meant to take off that carb to check it but didn't want to ruin the boots even more. Plus need tires for it becuae gas leaked on the back one giving cracks between threads.

This has went too far! Whats your deal? Your typing, and English are too bad, for you to be in college. Also if you don't know the difference between "RUBBER BOOTS" and an "ENGINE" you definitely have no business rebuilding carburetors. After trying to explain things to you as simply as could be done several times, you just keep getting further, and further out into left field. The guy's here on the forum are very eager to help, but you seem to be jerking us around. If you are sincere, and need/want our help we will be more then happy to help, but quit jerking us around.

Re: Honda cb 750A Carb problem

What? Your taking things way way  way out of proportion dude. My typing is because I was between here and working on the bike before I lost to much light. That has nothing to do with me being in college. How you think Im jerking is very awkward. Maybe personal issues.

I asked a legit question and got left field answers. Maybe your taking things too serious. Sorry to bother you and this forum if your still puffed up with thinking Im jerking you guys? Serious WTH face.

Learn to relax some, don't be sup up tight. Woo sa and learn to let loose sometimes... Heck its not like I talk like I type. Your comment really threw me off and makes me not want to take your advice next time. Its like going to the know how jerk who wants you to know how. Besides I got the carbs broke down put back together, why should not I be working on it?

Lawdy! All this over some carburetors!!!   lol

Alright,here's the deal. We all get excited to get our bikes fixed and it's easy to get carried away and in a rush.

Zonson, carbs can be a huge hassle to get sorted sometimes. Everybody here is here to help,but sometimes you just have to be careful with your typing to get the idea across so people can help out to the best of their ability. Sure,you might not know all the proper names of parts yet,but with enough info we can figure out what you're describing and we can all get on the same page.

Anyway,sounds like you got it sortedGood deal! But for future reference,even though ''things'' might not have gone so smoothly in this thread....

... I can assure you that Tools is the guy you want to talk to with any and all things 'matic related!!

rust in tank bad, will clog carbs causing flooding or starving, you need to clean that thing,
put an oversized fuel filter in line, and don't forget about the petcock, it's prob full of
crap as we type.

if it now will not turn over, charge the battery.

if it turns over, but won't fire, check for fuel (just pull the hose off) at the carbs, petcock might be clogged.

getting that rust out of the tank, cleaning everything it supplies,
making sure it doesn't happen again, that's a job.
