    82 720 noisy fuel pump

    datzenmike knows more on these trucks but on my 521 I swaped out my maunual fuel pump and it still didn't work. Find out the intake fuel hose had a hairline crack going long wise and was sucking up air instead of gas. Changed hose and was fine and the old pump was fine

    Not a 510, 620

    Man you must be RICH$$$$$$$ Open chamber more prone to pinging but you guys have 94octane I think up there.

    What broke now?

    this is me trouble shooting here. I have Mikunis Solex and the jet blocks would back out and cause a bogging issue when I really give it the gas. Also 1 time the tunnel venture funnel thing was loose inside causing a high speed cut out. I tighen it up where it wouldn't wiggle and was fine after that. As for ignition make sure the points are good and you use a stock coil and ballast set up. So if a coil or anything was changed we need to know. as resistance values do matter as points don't like a lot of current. Use a timming light and see what you get. I would adjust 12-14 with dual carbs. also make sure you valves are adjusted correctly not that its the case but I would drop a lash pad once in awhile but it more or like runs on 3 cylinders I don't think its a Head gasket

    distributor datsun 620

    a 68-72 510 had a point distributor. which needs a ballast resistor otherwise points will burn up. and the Start wire to bypass the ballst the later 510 (A10 had a matchbox )

    your right I was looking at wrong photo.

    Unless Im missing something its after the fuel regulator anyway. So I think your fine. Now for volt reg look at photos of the round connector and find that. or where you think it might be and maybe look for some jumpered wires. Most if they convert to IR TYPE ALTERNATOR. most time cut the volt reg off and them jumper the wires and plug it in to the harness

    wasn't the regulator on a 620s a round type connector?

    Just bought a 521

    The tail shaft seal make sure its a double lip type. I seen a SKF version and it had only 1 lip.. I replaced mine 3 times and still leaks.

    U67 Cylinder Head Valves

    Key is finding good head gaskets on this one

    Heater hose leaking

    Constant heat is OK and just use your vent to keep it cool inside if needed. Not that a old heater is really that hot. On my 521 I keep the valve ON to keep it from wearing out as its so old. I just use the vent flaps

    Poor braking

    I dont know if a brake booster will fix this. I have never run one on my datsuns and stop good enouff

    '77 point dizzy to Electronic Ignition dizzy questions

    I would take photo of the dist rotor pointing where it is and install the new one and esee where it points/ if close then you just adjust the bolt on the hold down plate using a timming light

    Info on long runner manifold.

    the NissanComp manifold was a a longer type. Be honest I like the short Mikuni ones as it fit better w/o hiting the brake master what ever is cheaper makes it Ezer but short wouldbe my pick for your truck. In a L motor the HP/torq gain you wont be able to tell as much I think. Just putting the carbs on will feel like a 50% improvment

    yes the carrier bearing needs to be unbolted. plus the 2 upper bolts in trans tunnel . ez ermaybe to remove plate where stick shift is to get to them When I change clutches in a 521 I just pull the motor. Its faster for me.521 is a pain
