    YOU ARE THE MAN! Thank you, man. Will try to put everything together tomorrow...something tells me I *might* need to buy a few feet of hose. ha ha. Thanks again for your help. Lifesaver. Will let you know how it works out.:pop:

    OK, so just looked at the pdf you sent...it skips from pg 298 to 500. ha ha. so 312 and 313 arent there. There is a diagram in the 500's but looks like maybe its a different motor than the one I have. hmmmm

    TYEDUP New Member

    ok..this is where you call me an idiot...pdf file page 314...not the book's page. ha ha

    wow..according to these diagrams, my poor hijet seems to be missing more than a few parts. No wonder it has no power. I think it is doomed. Simply dont have the resources or the parts to make it what it should be. :(

    one of the sponsors here should be able to hook you up with a used carb...a lot of the vacuum lines run from the temperature switched valve and you could just block some off and run with the choke in the warm position all the time (would just take a bit of right foot till it warms up) depends on whether it is meant for off or on road

    TYEDUP New Member

    It's meant more for off road. Just riding around in the desert. (I live in Az) It's been very frustrating as I have tried everything I know to do, and still seem to have the problems. And right now, I have been keeping the choke in the warm position, which seems to help. Since it's nice and hot here anyway, the motor doesn't seem to mind. It's when the engine warms up and is under load when I have the issues. I should take a picture and show you the motor, and you tell me what you think. I'll go take one and add it to my profile. Give me a few mins. Thanks again for all your help. :frustration:

    looks like the vacuum advance line to the distributor is missing

    TYEDUP New Member

    theres a hose running to the distributor that runs to the top of the carb, but i was thinking that's not where its supposed to go.

    The vacuum advance should run into the top of the carb...the advance mechanism inside the distributor may be sticky and not opening up....the air breather tube on top of the valve cover that is blocked off should be tee'd back into the intake manifold or the blowby may pop out a seal..check your timing as well (once all vacuum leaks are plugged)..should be around 10 degrees btdc at slow idle,...if initial timing is too retarded or advanced,that would give problems at higher speeds....

    A week ago, we got in the Mits and she seemed sluggish and LOUD. Step on the gas and there was no acceleration, just a huge throaty exhaust sound. Bumped my way down a friend's driveway and while the wife checked down at their beach to see if they were home I crawled underneath thinking hole in exhaust, no back pressure?
    Everything looked fine, and when we staarted it up to go home it ran fine again. Had a chat with the mechanic who said it wouldn't be the carb, distributor, vacuum advance he'd redone all that. Fuel starvation maybe, he guessed.
    Yesterday it did it again. Came off a mountaintop and when we hit pavement, same thing. Had to make a run back up and we couldn't get it over 80 kmh on the highway, and there was zilch revs climbing the hill in 2 gear LowRange.
    Had half a can of SeaFoam at home. Now every mechanic I've met pooh-poohs that stuff, but I had about 1/4 tank left so I dumped half of the half can in. Pulled the air cleaner and because of the sideways carb, I used a pastry tube to try the rest into the carb. Most spilled on the gravel, so it didn't run to a stall.
    Tidied up, put the air cleaner back and decided to try a run 15 minutes later....
    BY THE TIME I HIT THE STOP SIGN END OF THE BLOCK, the waaaaahhhhh just stopped, the truck jumped ahead and the revs shot up. Had to slam the brakes so I didn't run the stop!
    Ran it up the same section of hill I couldn't climb faster than 50 in 3rd this afternoon, accelerating at 80 in 4th. Wound it to 105 on the less steep parts. Pulled a Uey and hit over 110 coming home.
    $17 a can up here, have to drive to the next town during business hours but that **** WORKS. The SeaFoam guys can use my testimonial to talk CrappyTire into stocking it if they send me a case!

    You guys having problems with Ethanol must have suppliers that don't give a damn how much water gets in it. I have been running 10%+ Ethanol fuel for 10 years and have had nothing but success with it. When you tune for the Ethanol you will always get BETTER power and gas mileage with it. You can run WAY more ignition timing with it to give you a huge bump in torque and efficiency.

    Case in point, I am regularly knocking down 20+ USmpg in my Caprice with a 350 in it and a fighting weight of 4000lbs. I could never do that with Chevron 94 but I can do it with ease on the Mohawk 90 (yes 90) that I can get locally. With the Mohawk 94 I can run 32 deg. of total timing and 18 lbs of boost in my Skyline with only a 35 count on my knock sensor. If it's cold out (10 deg. C) I can run 24 lbs of boost at the same timing. Chevron sent the knock counts though the roof and scared the hell out of me.

    Where are you guys getting Sea-Foam in BC?

    Not sure how it is in BC but here in the states most all we get is 10%+ ethanol. :confused:

    NAPA and ARO carry SeaFoam, ARO has the best price. I have to drive to the next town as neither place here carries it.
    Likewise the gas here is all from the Husky refinery in Prince George. I really WISH that Mohawk was still around because I swore by their ethanol blend when I drove my old Ranger in winter. I'd "treat it" to the mid-blend (15% isn't it?) and it CURED both the crappy gas problems from the local stations and carb icing on the highway.
    I'm the son of a Chevron refinery chemist, I was stunned at how everyone in this town meekly accepted that you needed additives to run a chainsaw, lawnmower or outboard when I moved here. Even filled a 22L carboy and sent Dad a photo showing about 500ml of scum on the bottom after it sat for a week.
    Unfortunate result was that redoing the old bulk plant (traced problem to there) was too expensive in the small market and they closed down.
    I now fill only from a no-name with brand new above ground tanks. Every problem with the Mits was after using PetroCan Regular from the station here.
