1968 Honda CB77 Fuel System

1968 Honda CB77 · Fuel System Buying guide

Put together the order for your carburetor repair

The drain screw comes with an O-ring and is sold individually. A separate CB77 rebuild kit is linked below for broader service work; establish its contents before combining the two purchases.

Parts to consider

Choose the repair parts before the tools

Use the drain screw when that fitting needs replacement. For work inside the carburetor, compare your parts list with the linked rebuild kit before adding it to the order. A universal synchronizer is measuring equipment, and its presence in the product grid does not establish CB77 connection compatibility.

Account for a previous carburetor change

Both service parts carry a CB77 1961–68 application. If another carburetor or bowl has been installed, identify that assembly before buying. Keep its markings and a clear view of the drain fitting available when asking for a replacement-part comparison.

Common buying questions

Should I order the drain screw as well as the rebuild kit?

Check the kit’s itemized contents first. The separate screw includes an O-ring, but neither item is confirmed as part of the rebuild kit. Compare the confirmed contents with the parts you actually need to replace.

Does one rebuild kit cover both carburetors?

The available kit description does not state how many carburetors one package services. Confirm that coverage and the included components before setting the order quantity; the CB77 application alone does not answer either question.

Can I use the listed parts with replacement carburetors?

The CB77 application does not identify an aftermarket carburetor conversion. Check the fitted carburetor and bowl markings, then compare the replacement requirements with the relevant product before ordering.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
