I need help removing carburetors 75 CB200T, Pics inside!!

[Hybrid93Hatch]

I am having a fuel problem (I believe). This is my first bike (2 weeks now) so I am new to the scene. The bike is a 75 Honda CB200T which I plan to learn on until I grab a new VLX or Aero around summer. ON to the problems.....

1) The bike stutters when I get it jump started

2) Rarely will the bike start using the push button. This never happens when the motor is cold.

3) The fuel line on the right side carb drips pretty bad when the fuel switch is ON.

4) Throttle hesitates when trying to accelerate. Gets worst the more quicker the acceleration.

5) The bike didn't come with a kick start for some odd reason.

What must I do / remove to get the carburetors loose from the bike?

Is it a must to drain the gas tank? Do I have to remove the gas tank to remove the carbs?

Do the problems above sound like the carbs may be clogged or one of the needles inside bad?

Here are some random shots I took of the carbs:

Hey, it sounds like you have a splice in the fuel line. It might not be getting enough gas. Or your fuel filter is clogged. It should have a shut off valve under or on the side of the tank. My cb750, after its running and I shut it off, will leak gas from the overflow on the carbs. You can also check the filter for the gas tank. It should be located in the valve that shuts your gas off. It is just a little copper-like screen. I hope I could help yah. My bike is a beast. Super reliable! HONDA!

You don't have to remove the gas tank to remove the carbs. You just unscrew the top and the piston and needle slide right out. They stay totally intact so don't worry about them falling apart. Then just unbolt the carbs fron the intake. Watch out though the left-over gas in the carbs will spill all over the place. Now you have the option to clean them up. There is probably alot on crap where the floats are and stuff. The old gas in mine was like varnish. I had to scrub tham with a tooth brush. Good Luck!

They were really easy to remove. From what I can see they look pretty clean. But, this is my first time seeing the insides of a carburetor so I could be wrong. Here are some pics I took of them off the bike:

Looking into the carb. from the air filter hose connection:

This is wher the carb. connects to the motor. NO gasket there...

Both carbs. looking in again from the rear side like in the first pic of this post.

This is what unscrewed from the top of the carbs:

How do I dismantle them now? Where would all the "gunk" be if they are clogged?

Thanks again for the help!!

On the bottom of the carb there is a lever that folds over the whole bottom side of the carb. Flip that over and that holds that whole part on. Your floats are in there. They should be the old metal type. You could get new ones cheap if you wanted ($15). If you had the clymers book it would tell you how to make sure they are adjusted right. I think if you hold the carb up level and the float is parrallel with the bottom it is fine. You can adjust them with the screw that holds it on. But once you get that bottom of the carb off you can clean everything with a can of carb and choke cleaner. Use the nozzle extension and spray everywhere. I would also put new bleeder hoses on the carb. You can get them from any hardware store. Just bring in a peice of the old one. I would put on new gas lines too. Super cheap to buy rubber hoses. Your carbs look clean. yours are easier to put on and take off than mine. I have 4 and they are put on at the same time with individual boots for each one. They are not bolted on to the cylinder head like yours. Keep me posted. Good luck!

[Jimford]

Oh yeah and I would definitely put gaskets on where they are missing. You never know air could be getting in there. If you don't have a Honda dealership nearby you could buy some gasket paper and make your own. Or as a last resort you could use some sort of liquid gasket. I wouldn't mess with the needle or piston. They look pretty clean.

A friend from down the street was over and took a look at the insides of the carburetors. Said they aren't that bad looking from what he can see. He admited he's not a pro, but doesn't think they need to be rebuilt. He did recommend a good cleaning of the carbs. though.

Here are the pics:

What do you guys think? I believe the lady I bought the bike from said her father had recently cleaned the carbs. up.

Thanks again!!

They look pretty good! I would do a good cleaning though. Take out each jet and spray in there. You never know, one little peice of debris could make it run like $hit. Did you check the floats to see if they are adjusted properly? Make sure they move up and down freely. Did you check the fuel valve for a fuel filter? If I were you I would trash the filter thats in there, if there is one, and just use a lawnmower type one. That way you know that since the bike is so old that nothing is getting sucked into your carbs.

look dirty if you ask me.:o

[Jimford]

They are not that bad. The dark spots are like varnish. You really have to scrape that crap off. I used a little sandpaper where I could. Fine grit.

When I remove the jet does it have to go back in the exact way it was shown?

I don't know if they are adjusted correctly, but they do move freely up and down.

Where exactly am I looking for the fuel filter?

Thanks!

[Jimford]

you just tighten the jets in place. No specific way. Just don't over-tighten and strip them. The fuel filter should be in the fuel shut off valve. I wrote about it in one of my replies. It should be a screen-type.(useless) If there is one just take it out and get a in-line type filter. Most of them are clear so you can see when they are dirty.

Hey guys. The weather is just now warming up so I'm back at it again. Just took this shot with the pin pulled and floats removed. Sorry it's not that clear >> dark and I am having to hold both while taking the pic. I sprayed what you see down with carb. cleaner. Should I get the air compressor out and send air through all the holes? Thanks again for any help!!
