I am using NGK plugs, they were recommended on the Canadian tire website. I know copper is best but I got iridium for longevity.

 

I crawled under and pulled off the pump, the fuel filter was clean and mostly empty.

 

A couple knocks on the gas tank showed it was empty!

 

The gas gauge is at the first line after the E, is this line not the quarter tank mark?

 

I have never been able to tell if a tank is empty by knocking on it.

Doesn't look like I have air conditioning.

 

The gauge does go to empty when I turn the key off, and up when I fill it- guess I'm just used to the E mark being actual empty. Didn't look like the pump comes apart.

 

Fixed the loud fuel pump by getting a gerry can of gas & fillin' er' up.

Still wondering if the pump is meant to be silent.

With the car off, pulling the lights knob turns on the fuel pump...lol

 

At least It sounded that way, I'll check tomorrow.

 

Picked up some black leather seats out of an old Honda from the local pick n pull. They look race-ish. 30 bucks. Pretty cool.

Post pics later.

Yup and the bottom unscrews and has a magnet to collect rust and trash. Forgot to mention this was also an option on the '77 and up Camper Special the for-runner of the Cab Chassis option?  Likely this is an after market pump to replace the original one mounted on the outside of the right rear frame just ahead of the tire. A after market pump will require an in line filter between tank and pump.

Oh, on that note, the 12v+ line going to the potentiometer that controls the dash lights & fibre optics...dimmer I think it's called - had no power in it.

 

I wired it up, but still curious if it has... A fuse or something somewhere?

 

I have found...7 fuses, all are good.

 

The alternator seemed to be unregulated, seems fine now; With the deep cell house battery wired up to the alternator along with the running battery -I could not distinguish which little metal box is the regulator?

 

I'll try googling.

You will definitely regret putting a smaller dial steering wheel on your motor home, unless you seriously enjoy an upper body workout whenever you drive it. a

 

If you’re considering the 720 brake upgrade, and want a quicker alternative than a power steering upgrade, you might consider a 720 ST steering wheel.

 

Although the skinny brown fake wood on the orig 620 steering wheel looks good and is classic Datsun, the skinny wheels are hard to grab and turn while wrestling with it turning the vehicle around or backing in and out of a parking\ camping spot. The 720 wheels are twice as thick, insulated with rubber, don’t slip thru sweaty hands, and way easier to hold onto on cold mornings.

 

If you have a lot of patience, you can also recover the rubber with a leather kit from Pep Boys.

Over the past 2-3 years I’ve found 3 of those steering wheels in junk yards, $ 22 ea with the hub. Kept one for each of my vehicles and sold the 3rd. I can keep my eye out for you if you’re interested. There is a regular seller at the Eagle Rock swap meet that usually has one or two. If I recall he prices them from $75-100 depending on cond.

Sure, if you happen to spot one :)

Pulled the carb off and put a new one on.

Those 4 bolts...wtf.

 

And that emissions system - too much in the way, cluttered.

 

Turned over the engine and it just started screaming, guess that'll be the idle screw, gonna see about tuning it tomorrow.

 

Polished the head, +12HP.

Ya it turned out to be a fragment of throttle cable less than it needed, like a milimeter and also I was turning the air/fuel mixture screw and not the idle screw! And the choke mechanism doesn't hold it's place very well.

Had to hold the choke and push the throttle down after turning the idle screw out to the max.

 

But now I have sprung a leak. Bottom radiator hose was ice cold...top hose was hot. Overflow hose to resevoir was cold aswell.

 

The original carburetor is much more solid and less finicky. The choke mechanism on this new one is shit.
