    Did you compare yours with what they have?

    I sent Don my VIN.
    He says he has the carb I need.
    I'm emailing to see what is included.

    Hello Jon! Just checking on your progress? I believe you are writing for both of us with your problems. Lol. Hopefully come Monday we can smile a little more. I have everything important to pull mine too. Coffee ready, Camera, Radio. You know, all the important stuff. Good luck and hope to hear all went well for you on Monday.

    I pulled the trigger on a rebuilt carb from YokohamaMotors.net.
    It is in transit from Japan.
    I'm no carb guy and just don't have the patience to tear apart a carb I couldn't find a kit for.
    I can prob put the used one back n Ebay for a little change to recoup some costs.
    It can't be in too bad of shape since it runs great with the choke on.
    At this point, I'm just praying that the issue is indeed with my carb.
    We'll know next week. I hope.

    Sometimes a man's just got do what he has to do. Who knows, I just might need that carb when it is all said and done. Good luck with it. Wishing you the best.

    How much would you want for the carb?
     
  7. jwicker

    jwicker Member

    Make me an offer. I have no clue what they are worth.

    WOW - Hats off to Don and YokohamaMotors!
    Ordered the carb from Japan on Wednesday. It shipped on Thursday and arrived this morning via USPS.
    I can barely get a letter across town in that time.

    Now - to get busy with the swap.

    Fingers crossed.

    jwicker,

    Any chance we could get you to do a price breakdown in general section?

    I know many have considered making small orders from Don in the past, just the price of the extras has scared them away.
    Mostly, those prices are unknown.

    SHIPPING+DUTY+TAXES...+YEN-TO-US exchange card charges...I would think that there would be more.
    Would give guys a good idea of what it would cost them to get a 5lb box from Japan.

    You must be near a large hub center as well. For me, no wide-body airports within 8hr driving, so, this costs extra for international shipping...actually, it's the largest portion of the cost.

    PS, avoid UPS ground/Purolator across the border if at all possible....extra large charges seem to arrive two weeks later all the time. USPS, FedEx, no extra charges...:confused:

    I'll try to pull the numbers and post later.

    Hello JW, Any chance when you are done installing your new carb (Lucky u) you can post a pic of the old one? I would like to know for sure it is the same one I have before I decide if I can buy it. Thanks and hope the install went good.

    I'll snap some Picts tomorrow after work.

    As for the new carb.... It's on and hooked up.
    With NO adjustment it fired up without touching the gas pedal.
    It warned up and idled down to a nice rpm.
    The idle was a little rough, but it DID idle.

    I let it run for approximately 10 minutes and had to 'touch' the gas to rev it up and flush out the rough idle.

    I took it around the block and it ran great.

    BUT.... After letting it sit off for about 20 minutes it failed to start.
    It cranked and cranked.
    I even manually pushed on the choke.
    No go.

    Then..... I thought, "Hey. This thing isn't getting any gas. "
    So , I pulled the gas cap and heard a swoosh as the vacuum leg go in the tank.

    Left the cap off and after feathering the
    Gas pedal, it finally started.
    But, it DID start and run.

    Had to go put the kiddo down so I'll pick
    Up from here tomorrow after work.

    More to come.

    Well. After more testing, I don't think the old carb was my problem.
    Yesterday it just cranked and cranked.
    No start.

    Today, the starter sounds like it is trying to start a locked up motor.

    It literally shakes the whole truck and comes to an immediate stop.

    Any clues??????
     
  15. jwicker

    jwicker Member

    Ok so. I am HOPING that the latest issue is just a bad battery.
    With my charger on Start Boost, it DID crank a few full revolutions.
    No start, but not locked up either.
    I think.

    Be careful to not burn up your starter.You can probably get it re-built locally but still an un needed expense.
     
  17. jwicker

    jwicker Member

    After charging the battery more and putting the charger back on Start Boost mode..... It finally turned over 3 or 4 times.
    No start but at least it turned over.

    And yes... It has oil and antifreeze.
    Haha

    I'll put it on trickle charge and try again tomorrow.
    Right now, I need a beer.

    Considering I have no clue where the gas cap vent might be, I am soaking the stock cap in some detergent and water over night.

    I might resort to a drill bit and some careful planning to self-vent the cap.

    Before I get flamed for over posting to my own thread... Let me repeat that I'm doing this to document my learning process and my own HiJet experiences.

    So, with that, I Have to ask,:

    Has anyone pulled all of these vacuum lines off and replaced the stock HiJet setup with a simple motorcycle carb from an old 650 Honda or Kawasaki?

    With a manual choke and an electric fuel pump and a regulator... I can't help but think that there is an easier way to get past ALL of these many carb/running/ idling issues that seem to plague the HiJet design.

    An I missing something obvious?!?!

    Thx

    About 6 or 8 months ago someone did it.I think it was in the Suzuki section.He had a few problems but I think he got it running finally.The vacuum systems are a pain but sometimes trying to get around them is too since so much is inter dependant.

    Here are some picts of my original carburetor.
    Since my problems persist, I doubt there is anything wrong with the original one.

    I'll probably put it in the for sale section soon.
    I'll clean it up a but first.

    Maybe a dumb question, but what "sets the choke"?
    Pushing the pedal down once?
    Just the temperature outside?
    Temperature of the engine?

    Hello Jw, If dumb questions were a crime I'd be locked up. Can't offer an answer either. Hoping someone can cause
    I have been trying to understansd it myself. Seems like a lot going into operating that flapper. But I mostly don't uderstand the concept with the wax. Might try to google that.

    Well.... just an update....
    I was able to start the HiJet yesterday afternoon.
    I just pressed the gas pedal to the floor and cranked away.
    It finally started.... but was running VERY VERY VERY rich.
    So rich that there was actually a puddle of gas on the ground behind the muffler. Seriously.

    To say the least, it was smoking a lot.

    I didn't do any tweaking on the carb while running because Don at Yokohama indicated that the carb would be set and ready to go.
    Of course, if it was set... it was set to a stock setting for a new mini. Not one with a lot of miles that might have other issues.

    I'm wondering if the float might have been stuck or maybe trash in the needle. I hate to pull that &@%#*! carb back off.... but it ain't working as is.

    Thoughts and comments appreciated !!

    thx

    As you know, I am not a carb kind of guy. So take this as a sort of a parallel of thoughts that you may be having already. Maybe in the conversation a reasonable theory might surface. Start with this; Getting back to the idea of eliminating the fuel delivery system and trying simple gravity feed. If, and a big if, the spillback from the fuel pump was plugged (I'm thinking you have electric but don't think it matters), or if somehow the pump overpressured, could that possibly flood the engine? You would assume that the nedle valve would prevent that, but it's worth considering.

    I'll try to set up a gravity feed feed and catch bucket for the return soon.

    I'm no carb guy either - easy to see that, huh?!?

    Keep the info coming.

    thanks

    I haven't gravity fed the gas from the tank directly to the carb.... but I did eliminate the stock steel fuel lines and rubber lines.
    I pulled the tank (have not yet drained and cleaned it). Trying to eliminate one thin at a time.
    I put the tank in the bed about 2 feet from the fuel pump and ran new lines directly to the fuel pump.
    No change.
    It cranked and cranked and smelled flooded.
    Pulled the plugs and the back 2 were soaked... the front appeard to be dry...but hard to say (It took me a while to get the front one out).

    I put new plugs in last night and it finally started.
    Had to mash the pedal to the floor and crank a while.
    When it did - it was same as before..... LOTS of smoke and very rough running.
    Smell of gas exhaust filled my garage.

    I shut it off for the night.

    Thoughts and suggestions appreciated.

    I'll try gravity feeding the carb directly next.

    I STILL haven't had the opportunity to try the gravity feed of fuel to the carb.....
    but can't help but wonder - - out of all of these vacuum lines....... which ones could be capped off.

    Since it will not likely be street legal in my neck of the woods..... emissions doesn't concern me.

    Just wondering if i could eliminate some potential issues and get a root cause of this fuel issue.

    This thing is driving me insane.

    I have had it for quite a while and unable to use it.

    thanks

    Great question and one I've wondering about lately too. Hopefully we can get an answer to it. I've already removed the Cat in the hopes it would fix my problems. But not....

    Hey, one other thing if you should decide to gravity feed. I don;t think simply using gravity is enough to keep the bowl full. If you use a simple boat type pump-up bulb it seems to work okay. Above all though, and I am sure you know this, recover the gas coming off your fuel pump. Could be dangerous on a hot engine/exhaust.
