Let’s disassemble the carburetor. The image shows it after polishing, so it’s finished in excellent condition.

It’s in such good condition that you can feel confident about it.

The vacuum carburetor has few parts, which is excellent.

I get the impression it’s been corroded quite a bit.

You can see that the slide valve body is showing some wear.
DSC09438
The float fixing O-ring has also deteriorated and is loose.
DSC09437
The O-ring below the slide body has also hardened and is in unfortunate condition.

It comes together in no time, but it actually takes more effort than expected. I’d really like to use new bolts. It’s worth the extra care.
Even after an OH, I occasionally see crushed bolt heads or rusted parts being reused. It’s a shame because just a little more effort would result in a much cleaner finish.

The throttle cable is already discontinued, so we adapted one from another model. This gives us peace of mind.
