ok guys, i know nothing at all about vacuum systems and how it works. what i do know is if i pull a couple of random lines out it runs the same?? plus there is a diaphram lookin jobby attached to the top of the carb that has a hose that drops out from the bottom of the thingy and connects to the engine( that connecting niblet thing is clogged with crap and basically doesnt function. engine purs nice, goes 70 ish on highway(runnin 31's) . is there a way to test which valves and vacuum diaphrams are working? i have no clue where to start. just replaced the o2 sensor thisweeknd and also the spark plugs. i know i need a serious tune-up. any guidance would be appreciated!!!! if needed i will get pictures for you on the thingy area...:na:

I just got mine rebuilt (stock jap. carb.), and I wasn't sure about the vacuum lines either. And the guy that rebuilt it for me said that really the only one that mattered was the one going to the distributer. Past that it doesn't matter. So, I'd just say tinker with it till it works. I know thats what I did. And my engine overall isn't that good..but I've done some few minor other things and it runs pretty good now.

I think he said distrubuter.. heck I dont know 100% cause my dad was doin all the dealings because I'm 2 hours away in school.

Check the Hitachi vacuum pictorial at http://www.acksfaq.com (http://www.acksfaq.com). Do a search for vacuum in the FAQ Forum.

It shows where everything goes and, properly connected, will make a halfway decent hitachi run better.

There is also an idle adjust post in the Samurai forum FAQ section at Zuwharrie.com that bears looking at.

hope this helps!

This is a binding butterfly valve problem caused by a worn or bent pivot rod or worn bushings. If the unit is used, I'd consider sending it to Kevin "Sarge" Lafferty ( http://www.performancewebers.com/) for a rebuild. If it is new, send it back for warrenty repair.

My bet is that it ain't new...

:shocked!: ok, so i still am fidlling with the carb, unplug this and that and listen for suction.... i even unplugged the "important one" distributor vacuum... and nothing happened. i thought this one was the "one". so im going to grab a crapload of new vacuum hose and replace one line after another just to be sure, then i need to find out how to test this crap. question: is there a system or proper way to start testing? start here then go this way or is it a crap shoot and just unplug and guess???? can the little vacuum plastic jobies be tested? im in need of help for this subject,,,.
on top of this i think my oil pump is ready to go.... large 2-3" puddles of erl are dropping from right under the front at the bottom of the timming cover. i just dont know how long before it goes? will it go???? or just keep on leaking?? i will replace that part asap if needed, but what else is in that area that will also need changing, being as that i will be opening the front up... t-cover gasket, oil pan gasket, oil pump gasket, what more????? thanks guys.....

Take you timing cove off and take a look insde as to what is leaking. Clean it up real good and then see where it is coming out of. It could be just something as simple as the cam seal or it could be the oil pump gasket.

On the vacuum, if you are searching for leaks, start your engine and get a propane torch and let blow propane at all you connections (Obviously dont light the torch and just crack the valve open a little). If you have a leak the engine will idle up several 100 RMP's. There are several safety precautions you should take while performing this task like dont smoke, and dont do it in your garage. If you have any questions about the integrity of the vac hose change it out. If it is not pulling a vacuum take the hose off one at a time and blow through it to see if it is clogged up.


Disclaimer: Dont hold me or ZukiKrawlers responsible for any accidents, I would do this and have done this but you do it at your own risk. :mrgreen:
