That's neat they had a cooler air duct attachment on those too. Never seen that on a US market car.

I think the ea82 carb cars had that when they were new, I bet most are broken and gone by now. Would probably be pretty easy to retrofit into an ea81.

They were standard on the EA82 Carby model in Australia, but the cold air pipe went to the same spot as where the MPFI air cleaner sits in the engine bay.

I know, but just getting the linkage sorted out can be a challenge.

Have you ever tuned dual carbs before?

Hey Mark, Having any luck? During the warm weather the "Trasher" would start every time without the choke.Mine has a manual choke setup.Well now that warm weather is just a memory....Its getting harder to start,very hard.Most cars with a manual choke have a pattern to get it started. Pull all the way out and then 2 pumps or something like that..I can't find that with mine.Its like full choke and pump like crazy then push it in a little and hope it catches....and then pray it keeps running as it warms up. so I'm thinking its a fuel problem cause it starts right up when its warm ,by the sun or just by running.All I have ever done to adjust the carbs was just adjust one ...then the other one...And it seems to be ok..till now.You know mabey i just need a tune up or a hotter coil.Is there such a thing? So Mark ,good luck over there in Big Sky Country hope all is well

progress! I quit one of my jobs so now i have a lot more free time to tinker. The motor is ready to go back into the car, and i am seeing all the parts i am missing.

I dont know what the solenoid looking things on the front of the carbs do or how to hook them up, i am missing some return springs, various linkages and flanges, and the whole upper pivot bar. also i have no idea how to hook up the vacuum ports. :-\

I am also starting to think i dont want this motor in my wheeler wagon... not very much low end torque from what i understand.

I can tell you the soleniods are for the idle circuit, they need ignition switched power to turn them on and when the ignition is turned off so do the solenoids.

I had one of these motors in an MY wagon and in low range it was very hard to bog ... the only way I could bog it was leave the tyres completely inflated and have the car full of people, and as soon as the tyres were deflated it would dig it self out of the sand with 5 people in the car.
