Outer Limits 4x4 Board

Simply put it maintains a vacuum in the crankcase by controlling engine vacuum via a spring and ball . If the windage or cylinder leakage is too high that valve prevent the built up pressure from getting into the intake and leaning the engine out. Under normal operation it pulls enough vacuum to ...

It's a re-badged Nissan , there was a big write-up on Off Road .Com .

The valve cover (primary) side idle mix screw will always be more sensitive since it's closer to the main runners by about 1/4" . Most Zuks need a 65 idle , sometimes clear up to 70's . Throttle response should be crisp and nearly violent in lower gears . If it's lacking at an area just above the ...

We used to do that on Zuks but the only real cure is to rebuild it if you have that much blowby . The rings on these engines are pretty sensitive to carbon buildup . If you are referring to the screw that holds the pump nozzle the center of it has a lead plug to hold the check ball inside and seal ...

Jetting is the same , just a good normal highway cruise speed, rpm's around 4,000 or so with a normal load against the engine . Key is to use the smallest idle jets you can get away with , as long as it doesn't have a flat spot just off-idle it's good . Response should be fairly crisp and quick ...

Drop the secondary air down to 165 , pinging is a very bad thing for rods and pistons . Optimal fuel mileage is gotten with the primary at about 1/2 open, which should be around 1/3 pedal on the Zuk . It should always at least run on the primary , even on hills if everything is right with the engine ...

I just bought another 38DGAS electric choke off Ebay tonight , lol . There's another one coming up in a few days but it's listed for a Jeep so it will go high $$$$ . Idiots...

I wish I could buy stock in eyeglasses everytime that thread is linked

I'd be surprised if they sell hardly any at all . Brand association isn't really going to help here , the folks that buy trucks that size are pretty informed and have fairly high expectatioins . Just the fact it looks like the Nissan is going to hurt it . They would have better luck bringing back ...

You know, that's not a bad idea allowing the axle to work semi-independent of the springs . This way, the axle cannot wreak havoc on the springs and allow the traction bar setup to take the full torque . Question is, can you mount the bar solid enough yet prevent shock loads? That is the biggest ...

Ok, so it sounds like the whole issue with the engineers is basically the spring over ? I can see also where inconsistency between states would cause a problem, we have the same issues here with emissions testings . Since I build carbs , some have to be set up for testing , the variations between ...

One post deters nothing here ...it's all in good humor . Our laws are well beyond reason , but the one thing that would cause war here is too much gun control , that will never happen . The desert trucks I refer to are more of the stock class , high suspension travel at reasonable amounts of lift ...

Ok, got some time yesterday and starting tearing into diaphrams . The EGR was easy enough to get into and remove it's rubber section . The vacuum advance, however, wasn't nearly as easy. The way they crimped that thing at the factory suggested someone may use it for an anchor point ! By the time I ...

I currently use a triangulated type like someone had posted a drawing of , this is the one offered by Breeze Industries in Canada . Excellent design and works great but can really shock load the driveline easily . It's triangulated design controls spring wrap nicely, haven't damaged a set of springs ...

Sounds like it's time for a Revolution , I can't believe you guys put up with a government making laws like that . Think a lifted vehicle can't perform manuevers? Check out desert race trucks ! Your only problem is wheel base length . You need to either increase wheel track width a lot or do a lot ...

If you have time there's a mod I've considered but just haven't had time lately to tackle- If you don't use the EGR valve ( I have about 100 spares here) I've thought about taking them apart for the diaphram rubber itself . Since they are subject to high heat they are a bit tougher than the disty ...

A manuever like that would put 2/3 of the modern SUV's over here on their lid easily-I've seen it firsthand more than once . One thing I forgot to mention on mine- 2" backspaced wheels . It's nearly 12" wider than the stock wheel track . That test by Consumer Reports was rigged , flat out . I've ...

I don't think locking the hubs is a good idea . For one, spinning a lifted front shaft at high speed is a bad thing , the added drag on the front end will probably cause more rear tire lift than usual too . Let me get this straight- Some bloke is going to do a lane-changing high speed maneuver in ...

You may be able to source the advance from the dealer, or a vendor like Suzisport . Over here they are a bit hard to obtain . Check the weight springs and weights in the bottom for sticking and clean up the posts while you're at it . Unless you want to dive into re-curve on the timing , that's about ...

Ok, that drawing is the same disty as the early carbureted versions here in the States .... easy enough to rebuild if you can get main shaft bushings . Side wear is a problem with them since it changes reluctor gap and breaks up the spark at high revs .
Sarge

Those springs, just by size look like a high-bias limited slip . Does the internal parts actually have teeth or are they like clutch disks ?
I'd bet anything that is not by Detroit , they don't market any diff of that type for the Suzuki's .
Sarge

I'm just not sure what your countrie's market was offered , here we only had 2 versions . Early mechanical disty's used a standard electronic reluctor pickup , similar to Chrysler . Later efi engines used a full electronic disty controlled by the efi's electronic module . My emails with Nik are ...

The distributor needs vacuum off the "timed port" on the Weber . I don't run pressure regulators on these carbs anymore , just use the second fuel outlet on the carb for a bypass/return into the stock mechanical pump return line . You can just tee it into the return so excess fuel goes back to the ...

That's the part , although the ones I use have a longer piece of pipe for welding them . The idea behind using a flex joint is to prevent stress against the collector gasket . The header , since it's bolted solid to the engine acts like a torque arm when the engine mounts flex under a load . Over ...

Guage is the measurement used in wiring and sheetmetal , standard English stuff that makes no real sense in the world . The higher the number, the thinner the material/wire .
Sarge

The tubes have to be mandrel bent , my older header has no dents or internal diameter changes at all . If you use a 3-bolt collector type like Calmini's you should still use a flex joint . It also helps a lot to use the dead-soft copper or aluminum collector gaskets instead of the included composite ...

The biggest trick is to check the shaft side play against factory specs, once it's loose the shaft has to be re-bushed or it will never run correctly. Otherwise, a good lube and cleaning is all most of them need .
Sarge

If I had to guess , about 22 guage . Haven't been able to find my sheetmetal tool lately for some reason .

You are correct, pairing of the cylinders is what produces the scavenging effect . Here in the States, Calmini and Thorley produce the best tri-y designs overall . I'm not familiar with what is available in Australia , but I'm sure there are some decent designs . I've heard Calmini is releasing a ...
