Carby clean up with pics!!

Hi all,

This is a quick over view / guide to the stock carby for CAG's.

The two pictures below are - in order - the reed side of the carby & the airfilter side. You can see the choke plate on the air filter side.





As you can see above - you can end up with all sorts of dirt and stuff stuck behind that choke plate - so when you clean up the carby - make sure you clean all that area as well. 8) picture 2 has the choke closed [up position]for cold starting. picture 3 has the choke open [down position] when your engine is warm and ready.


This picture below shows the bottom of the carby, this is where the bowl is located. The two screws on each side hold the bowl to the base of the carby while the middle screw is a drain screw. So BEFORE you take your carbie off - make sure you under this screw and drain any fuel you have in there. This is also useful to check to make sure your getting a good fuel flow.



Below is what you find when you open up the bowl - the most common problem is that dirt & grit get stuck in this area.
Note the golden forks/prongs - the way the carby works is it fills up the bowl with fuel - the white thing you see in there is the float - it in basic "floats" up when the bowl is full of fuel and closes the prongs. However - if something is stuck in between the prongs valve or something hinders this from happening - you get fuel flowing out the over flow as the bowl fills up but does not shut off the prongs. It can be as small as a bit of grit. to remove and clean out this, you must remove the steel pin from the gold prong and out comes the valve [needle] make sure you blast out the tiny hole with wd-40 where this needle valve sits The gold bit in the centre is the jet




As you can see below I was trying to get a shot of the valve/piston the prongs move when the float moves up on it. This entire area must be clean - spotless to the point where you wonder if its the metal or your eyes playing tricks on ya for bits of grit. **the gold screw on the side is the idle screw**


Also note the seal I have there stays on the carby - make sure you always check it for cracks and stuff - if you don't get the seal right it will leak. Of course unscrewing the jets and blowing everything out can't hurt if you have already pulled the carby off and undone the bowl
Its really as easy as that. There are other carbys, one of which I will have tomorrow and I"ll add the pics for those and guide as they are a tad harder. These carbys as you can see are very easy to pull apart and pul back together again. Remeber to always use clean rags with carbys. I also like to keep an old paint brush and use fuel to give it a good going over as well.

Well thats it - any questions pm myself or RD racing!!

Finally managed to get some spare time

hope it helps!!

hoping there is no new threads started about carby cleaning now...

Isn't there suppose to be a pin in there somewhere that has to be alligned for the bike to work right or something?

eyah I was chatting with RD about that - this carby was my spare one and I didn't wanna pull my current one off the cag - however its due for a clean up so either tomorrow or early next week I am going to add pics and guides to checking the jet & how its put together along with the pin and how to set the position.

there is a pin that is located inside the main slide area of the carby, when you re- fit the [black plastic slide] into the top end of the carby you must position this so the black slide will fall into the carby top section without any force, this pin is a guide for the slide. must move up and down as free as.


**EDIT :lol: thanks RD :oops:

Wow now I have no idea what your talking about with black slide and pin. I'm going to try to clean my carb tomorrow so i guees ill figure out and come back if i have problems.

What do you need to do to get the carb off the engine. Is it the 4 allen key screws? And I thought carbs had 2 jets in your pictures there is only one.

where the red marks are, there will be 2 allen key bolts holding your carby to the manifold.
