Question about 1985 Nissan King Cab

1 Answer

Ok, so I installed a new weber 32/36 DGEV by Redline carb.

All went well with the install and I had very impressive results....until the engine reached normal operating temp, then it fell on its face. I have reset the idle screw and mix screw (per enclosed instructions) 4 times with the same results. I have also installed a fuel pressure regulator set at 2.5 lbs as the install guide says 3 lbs max. I have a decent idle (a little rough which I believe is vacuum related)but it simply won't accept any more throttle than idle speed. I suspect the vacuum lines are playing a part in this so I am going to check them and make sure there are no disconnected lines as well as no cracked lines. A vacuum schematic would be helpful and my chiltons is no help at all. Did find a you tube video that looks like it might be useful though. Any thoughts? I would welcome any and all suggestions. Really looking forward to getting my little truck back on the road.

I have a Weber carb on a Suzuki samurai. Runs ok but continues to try to run after turning off


this is caused by mixture getting past the idle and being sucked into the combustion chambers and being ignited by the hot spots and combustion pressures
Very common on early english cars and some american cars
The japanese carbies had a solenoid valve that fitted into the idle circuit so that when the ignition was turned off , the solenoid closed off that idle circuit and prevented the problem
you may have to "play " with the idle mixture screws to get a better mix so that the mixture is too rich to run on or change the weber to a model that has the solenoid shut off

Depends,I have a 85 nissan,see my icon,silver 4x4,The engine and carb.went bad,I replaced both and that has been over 3 years ago and it runs better than new.I also replaced transmission,it is pricey,I bought a new remanufacturd engine with 3 year and/or 100,000 mile warranty,The weber carb. was new,transmission was a new remanufactured with a year warranty.Are you wanting to keep car a long time,if so,but check price first.Find a asa certified mechanic to install,I used Jasper Engines,check them out.

Stock carb or weber 2 barrel whats going to best for mpg this is a daily driver 258 6cyl would like to get close to 17mpg


i would go with the weber.this is why.

Weber - This is probably the most common carb conversion for the 6 cyl Jeeps. The Weber is a very reliable, all mechanical carb that improves performance and drivability. The Weber is designed to supply the proper amount of fuel determined by the demand put on the engine. When demands are small, only the primary barrel is used, and when demands increase, the second barrel is used in to deliver the performance needed. Use of thie carb allows removal of all the electronics associated with the BBD. The 32/36 DGEV model claims 18% hp increase over the stock factory carb as well as 10-20% fuel economy increase. The 38 DGEV model is designed for higher power applications where headers, cam, and aftermarket intake manifold are used. $$

Howto install weber carb


Remove the old carb.  Bolt the new carb and gasket onto the manifold.  Hook up the fuel line and clamp.  Thread the throttle cable through the linkage and tighten.  Have someone hold the gas pedal to the floor, look inside the carb and make sure the throttle plate inside the carb is full open.  Next, wire in the electric choke, this should just clip on.
Now after the engine is running and warmed up...adjust the mixture and idle speed adjustments on the side of the carb.  Is this a two barreled cab and does it have a manual choke?

Vacume/webber problem


Is it the 32/36 weber or the knock off 34/34?

If its the 32/36 then the only vacuum line from the carb goes to the advance on the distributor. If standing in front of engine there should be a nipple on the left side of the carb.

Then there's the vent nipple on the carb. That'll go to the charcoal canister. There should be 3 nipples on it. It'll go to the far right one. If there's nothing on the middle nipple then plug that one.
