Topic: 73 cb750 carb feed?

[izaleth]

i Purchased a CB-750 in pieces and i dont know what goes where on the carbs related to overflow/ gas inlet any help would be greatly appreciated!

Float bowl overflow is from the tube in the float bowls. Fuel is fed via tw “tees” between the carbs (replace the “0” rings), and each carb has a vent pipe from the float bowls (up).

so the larger fittings are feeds and the two in the very center of the 4 are vents?
also should the T's be loose? it has a lot of play, i assume there are seals that have probably gone bad?

They will rotate up and down while mounted between the carbs with some resistance. Each side of the tee has 2 o-rings so 4 per tee and 2 tee's make for a total of 8. Do you have a Clymers or other type of manual yet ?

Correct on all counts. Replace the fuel feed “0” rings.

I can do you a copy of all the genuine honda workshop manual on a dvd as pdf pages, i aint good enough to make it searchable though.
Goes all the way from CB750 to the F2 and some parts books about $8 plus shipping from UK
