I got one a few months ago. I had a mechanic look at it and he told me that the choke was stuck open by the last owner and the carburetor needs to be replaced. Every one I have talked to has said that buying a rebuilt one is a nightmare. I think I'm going to break down spend the money and buy a new holly. Hopefully I can find a adaptor kit and the right kind of carb. If any one can give me some advice it would be much appreciated.

I have owned this 1985 Nissan 2 x 4 pickup since purchased new. It has a wonderful character and it is the only vehicle that I have owned that I will never part with. It has crossed the the United states over five times on interstates for long drive periods at 80 + mph and never a fault on the vehicles performance. Stay up on the maintenance and the vehicle will treat you right. I have over 140,000 miles on it, but this truck never sees the snow of the Midwest, but is garaged next to the 1991 Nissan 4 x 4 that comes out in the winter. The motor has a little noise above legal limits, but run it at road speed and its nearly silent. I am having some trouble with the idle, its dies from time to time, have replaced the vacuum lines, plugs, wires and to no avail, but have read a entry in this that says something about the computer under the drivers seat and will soon check that out and see if its the culprit.

I have a 1985 720 King Cab that my father-in-law bought new. If I remember, he paid $5800. I live in San Diego county in the Cuyamaca Mt. We are at 4800 feet. It snows 5 or 6 times a year, rains 14 to 19 inches. It can be 105 in July & 10 to 18 degrees in January. It has 266,500 miles.

It's had 52 oil & filter changes, 12 air filters 4 brake jobs. My son overheated it at 180,000. I had to buy a rebuilt head on eBay for $250.00. It took a week to change it because of the timing chain (we had to rent a tool from the dealer to hold it). 4 months ago it would not start it wasn't getting fuel.

After 2 months of messing with it I ruined the battery & starter it turned out to be a fuel pump relay switch.

I just graduated high school with an 85 720 King Cab 4x4. When I got it, it had a blown engine. But I had another engine in a parts truck for my 86 D22 that I traded for this one.

I absolutely love this truck. If I get it stuck in the mud, it winches right out.

I'm doing some restoration work to it now. It has a flatbed that I hate; getting an original from the junkyard and putting a fuel injected intake on, since carbs are far too expensive. I'm doing a camo interior and black paint with camo accents.

Nobody else around has a 720, but a lot of my friends have Frontiers and D21s. This is gonna be my kid's first truck one day.

Ah yes the infamous relay switch. It took my mechanic 2 months to figure that one out. After that, it was a new truck again!
