    the plan for the weekend is to give the the 73 hilux some over due lovin . got a igntior ignition, flame thrower coil, new fuel pump , filter, bosh cap and rotor. and a distributor. that should make the old girl purr. my question is on the distributor there is a thumb screw to adjust the advance , starting point in the middle ? as i type it sounds like a stupid question, however i was thinking some one may have some experience with this set up. and on the left inner fender there is a vacuum/emission box with 4 hoses where are the proper ports or can i just delete if so how thanks in advanced for the help or ridicule

    I suspect what your referring to is known as the "octane selector" on the distributor near the vacuum advance unit.
    If your distributor is new or rebuilt new, you should not have to touch it.
    It would take too long to explain how this works on this thread. Research settings information online if needed.
    Basically it allows you to match ignition timing to grade of gasoline. Not as crucial today as it was 40 years ago.

    put the new fuel pump in, filter, distributor ingitor and coil not hooked up to wiring harness. cranked 3 revolutions and stopped tried to turn the crank by hand stuck. pulled plugs tried to crank #3 shot a stream of fuel out .cranked till no more fuel came out. reinstalled plugs hooked up everything it started and ran but timing is way off try again tomorrow. last picture its fixable right

    Get a good manual and go back to basics. #1 TDC on compression, are timing chain index marks aligned? Crank pully marks at TDC?
    Get the thing running then adjust timing to where you want it.

    order a Toyota 8r-18rc manual. tried to re set the timing i do believe Fred is on the right track when rolling to the timing mark with #1 plug out i seen a shiny on the top of a piston. did a compression test #1 130 lbs #2 150 lbs #3 150 lbs #4 150 lbs found a spec of acceptable min 127 lbs with a difference of cylinders 14.2 lbs. how hard is it to change the timing chains and gears? is it do able in the truck or just pull it out and do it on a stand. thanks to Fred for pointing me in the right direction .

    pulled valve cover , front cover , the timing chains junk on the pump shaft you could see the teeth at the bottom of the sprocket , and the key way was broken on the crank. so Fred Heath was spot on why i couldn't get to run right. so now what do a motor swap like every one esle , no not me. new crank , found a 8rc NEW oem head for a steal , so more compression , from 8.5 to 9 . motor and tranny came out yesterday . next weekend off to the machine shop to get piston measured and bore for the next set of pistons so total rebuild.
