Today we’re going to work on the carburetor.

The intake manifold was as hard as plastic, so it took some effort to remove.

With an angled screwdriver and a Phillips head, it comes right off.

P1640595
It was already rock solid. We’re lucky parts are still coming out—once the intake manifold gets stuck, it’s a real problem, so we recommend getting it done sooner rather than later.

We’ll give it a light cleaning and then check the inside.

It’s one of those cases where hardened parts broke. Frustrating stuff.

P1640596
The hose is too stiff to pull out, so we’ll cut it and remove it.

P1640597 P1640598
The condition turned out to be better than expected.

P1640603 P1640604
The gasoline had deteriorated and fused the needle jet and needle together.

P1640605
We carefully dissolved and separated them without forcing anything.

P1640599
The bottom didn’t show much corrosion from deteriorated gasoline, which is good.

P1640611
The float valve needs replacement this time. It won’t return—we could make it return, but at this point it’s definitely a source of trouble.

P1640606
The slide block is a critical part that isn’t sold individually.

P1640609 P1640610
We gave it a light polish and cleaned it up. There’s minimal wear and it’s in good condition.

After polishing, the carburetor snaps right back together. Nice and crisp.

We only got this far today. We’re putting it on hold for now.
