is anyone running a fully stripped no emissions ea82 with a hitachi carb?

I want a motor with nothing on it except pcv system, disty vac line and manual choke.

I am wondering if a hitachi carb can be made to run smoothly on this motor if everything is plugged off.
also is it possible to remove and block off exhaust tubes, for lack of a better term?
any replies are welcome.

Contrary to what most people think, there really is not any emmissions equipment on there that will reduce your power. The vacuum lines are largely for the evap system (to catch fuel vapors that evaporate on hot day with the car not running - eg: in a parking lot). The only real emmissions bit is the air injection system, which unlike a smog pump, does not use engine power. It runs from the exhaust pulses.

To answer your question, yes it can be done. You just have to know what each thing does, and why it's there. Once you know that it's easy to decide if it's ok to be removed or not. The Hitachi really doesn't have anything more than a Weber that it truely "needs" to run correctly - except the vacuum choke pull-off. The Hitachi is actually quite a good carb, and really not much different than a weber except for beign smaller, and having a vacuum secondary. The engine can be stripped down just like it can with a Weber.

None of this applies if you have a feedback carb - that's a different ball game.
