    The best and easiest way to clean carburettors is with an ultrasonic cleaner.

    Yeah, it looks good, but I did notice that you put the metering diaphragm down first and then the gasket on top It should go gasket 1st then diaphragm (Hope that makes sense) Look at 1:40 when you are peeling them apart and then at 7:40 when you are putting it back together.

    A good source for Zama rebuild kits is This is Zama's website. Here you can enter in the information from both sides of the carb to come up with the right carb kit. This site also provides diagrams just in case you blow your rag away with your compressed air. :)

    The part number from Zama for the Syringe (primer bulb) is: 0057004 and a carb kit number would be maybe an RB-29? <--- Just a Guess.

    Have fun and keep up the good work.

    Great instructable, but do yourself a favour and use nitrile or pvc gloves when you spray carb cleaner and the likes on your hands. These types of solvents get absorbed into your body, destroy the skin layer below the surface and cause all kind of long term skin and health problems, most of them irreversible!
    I found out the hard way, after many years of exposure to solvents.
    Some barrier creams provide protection but read the labels carefully, to make sure you get adequate protection.
    Keep up the good work.

    The carb numbers on it make it look like a Zama but I know it's not, Although I know I have seen carb kits that include those exact gaskets for the fuel pump and metering side. There is a couple finer points like lever height, checking the check valves, throttle shaft wear, stiff diaphragms or curled up flaps on the fuel pump gasket, accelerator pump check, But this is an excellent start if you are just rebuilding a carb that doesn't have a rebuild kit. If you are worried about the gaskets getting damaged with the carb clean, just use gas to was them off. I also like to put some gas below the diaphragm and on the gaskets through out the reassembly steps just to make sure they are ready and not dried out from cleaning. anyways thats my over technical look at it all. Good job on another helpful video!
