Can anyone tell me what carby this is? I can't seem to find and names/numbers on it.. It's on my EA-81 in my Brumby.. Am I right to assume it's the stock Hitachi?

Looks like a Hitachi out of an EA82 with a manual choke but, where are the linkages for the secondaries?

it's an EA-81 with a manual choke.. and as far as linkages, you might as well be speaking japanese to me :/

It's just one of many versions of the EA81 Hitachi carb. I had one like this on my 84' Brumby. There is no linkage from the primary to secondary, secondary is operated by a vacuum diaphragm somewhere in there. Also you have a solenoid on the fuel bowl vent, that line should go to the carbon canister.

if you had it off car, and hit it with a cleaning fluid such as brake cleaner, wax and grease remover - you may likely find the numbers printed or etched on around the float bowl outer.

EA82 carbs don't fit the EA81 without the EA82 intake manifold as well.

The mounting bolts are a different width and the intake hole is smaller on the EA81.

Yeah I know. Where does the top radiator hose go on the inlet manifold, on the front or back? Manual choke looks like EA81 but I haven't seen an EA81 with the two fuel lines before!?

I just noticed the radiator hose in the first picture going to the back of the manifold, so it is a EA81 manifold.

bit tricky to see but that is fuel line in on the left, but the gold zinc fitting also has a return line off it, the middle hose, then guess the one on the right is vapour line out via the solenoid. The zinc fitting is useful at least on 85 moel year Brumby when fitting twin carbs, just the threaded fitting end goes into a fuel line before both carbs

So some Brumbies had a return fuel line?

Mine does - to the fuel filter.. it's weird as the fuel pump is up the back of the vehicle similar to the L series. I'm leaving it like this as I don't want to play with anything that could be there for a reason I don't know about
