    Rebus is ALIVE!!!

    Hello All,

    Over 12 months ago Rebus' distributor hold down bolt worked itself loose; the old mechanical fuel pump was well and truly on its way out too. Then the starter motor died. Then my work contract ran out in October 2015. So for the rest of 2015 and all of 2016 found all work stopped on Rebus.

    In April this year I started working again! I replaced the mechanical fuel pump with a Facet Electronic Fuel pump and I installed a set of new fuel lines. Over a period of time I eventually tracked down the correct Stromberg carburettor for the Holden 202 red motor that was manufactured in 1977. When I bought Rebus off the previous owner it arrived with a carburettor off a Holden 161 cubic inch motor instead of a 202 cubic inch motor. The previous owner described how during highway drives the engine seemed like it was sometimes starved of fuel.

    Today I set about finding Top Dead Centre. The turning the fan by hand technique so the motor turns over without the spark plugs installed did not work. So with the aid of three bolts threaded into the harmonic balancer I used a steel bar between the bolts so I could turn the engine over. TDC found I lifted and lowered the new electronic distributor - a Bosch clone using Bosch parts - until the rotor button was located at 5:00 o'clock mark. The Old Holden website mentioned that electronic distributors have Piston 1 at 5:00 o'clock and the old points distributor has Piston 1 at 3:00 o'clock. This was damned handy information to have! The information was sourced from the GMH Torana forum - turns out it is highly likely that with the engine number being XQL the donor car was a Torana. Accessed July 23, 2017 from Holden Rotor Button Position - Engine - GMH-Torana.

    So following the advice from the GMH Torana post and the nice close up photograph supplied ....Holden Rotor Button Position - Engine - GMH-Torana.

    I turned the key and waited to the change of pitch in the electronic fuel pump and then turned the key.

    This is what happened next ... Rebus Lives - YouTube

    While the engine was ticking away I noticed that fuel was dripping down from the main float section of the carburettor. I will take the top off and see if I can adjust the float to reduce the amount of fuel. I will have to sort because fuel dripping down over the hot exhaust manifold is something that takes precedence over fine tuning the motor with the timing light.

    If adjusting the float in the carburettor does not fix the leak I willl have to research what the flow rate out of the original A/C Delco glass bowl mechanical fuel pump is. I may have to install a flow rate device and the check to see if the Holley fuel pressure regulator needs to be re-adjusted to keep it set at a steady 4.5 psi that the Holden Stromberg carburettor prefers.

    Anyway, it is great to have Rebus back into the world of the living again.

    Kind Regards

    Hello All,

    I opened up my copy of the FB/EK Holden Stromberg Carburettor Enthusiasts Guide (p. 53) and also found the specifications for my Facet Cube fuel pump. The fuel pump is rated at flow of 32 US Gallons per Hour. Then after a quick conversion from US Gallons to Imperial I found this little bit of information


    Fuel Pump
    Maximum Pressure (psi)
    Free Flow (GPH)
    Early Holden (grey/red glass bowl)
    4
    9 (Imperial)
    Facet FAC-40106
    Set to 4
    27 Gallons per Hour (Imperial)

    Stromberg Carburettor details Carburettor Guide | Throttle | Carburetor

    Facet Fuel pump specifications Accessed July 23, 2017 from, FACET Solid State Fuel Pump 40106 4.0-7.0psi

    Just going off the comparison the Stromberg Carburettor is getting three times the prescribed amount of fuel per hour than what the FB/EK Holden Stromberg Carburettor Enthusiasts Guide recommends.

    I found plenty of fuel pressure regulators online. However, I have not come across any component that offers an adjustable flow rate.

    Has anyone come across one somewhere?



    Kind Regards

    Free Flow (GPH)
    Rated free flow rate is of course a maximum, a pump with a closed off outlet could still generate 4.5psi with zero flow rate. These things are not constant displacement like a vane pump. A pressure regulator is all you need, or a return line to the tank to bleed off excess pressure. I used to fit 3/16" metal return lines to certain vehicles to reduce the chance of vapour lock and flooding. Dead easy to do with a suitable tee piece or two.

    Hello BeeUtey and All,

    Thank you for the information about the fuel supply.

    When the Holden motor was put into the Series III the conversion place fitted a Dellorto Throttle wheel onto the carburettor. The throttle cable is fixed by a hex head bolt that initially goes through the throttle wheel. The cable itself threads through a hole in the threaded part of the bolt. The cable is then mounted to a hole drilled through a piece of angle iron via another hex bolt with a brazed fitting. The cable slides through the brazed fitting.

    A similar brazed bolt connects the cable to the original Land Rover rod linkages which lead back to accelerator pedal. The rod to cable conversion is held in place by another length of angle iron.

    The car will need a full inspection and road worthy because it has been unregistered for a number of years. Should I replace the bodgey hex bolt adaptation with something like a factory manufactured throttle adjustment like the one in the second photograph - that were made for a motorcycle hand lever?

    The first two photographs are examples of the Delltoro throttle wheel

    Kind Regards

    Hello All,

    After some tinkering and numerous attempts to get the one adjustment on the accelerator cable I can now turn on the key and get the engine running. I can step down on the accelerator pedal and then have it return to idle all by itself. So for the first time in what must be close to two years I took Rebus for three drives in the paddock. One of these rounds of the paddock was done under lights.

    I will be installing the motor bike brake/clutch cable adjusters so that it is going to be easier to fine tune things. At the moment the only adjustment is pulling the end of the cable with a pair of pliers and then tightening the single cable pinch bolt. It is a very hit an miss affair at the moment. The motor bike cable adjusters are going to be more user friendly.

    Next task after that is to bolt some metal plate cross pieces on to the angle iron with two holes drilled into the steel. These holes will allow me to hook two new throttle return springs near the swivel point of the original Land Rover accelerator mechanical linkages.

    Eau De Parfum

    Hello All,

    I used Rebus to shift two loads of pruned branches from near the house to where I formed a new pile in the paddock. During the process I noticed that there was a distinct Eau De Parfum of burning clutch. Also, the feeling of trying to overcome a very well bedded-in hand brake before any initial forward or reverse movement occurred. Trouble is the hand brake was not on at all.

    Looks like - from the smoke; and smells like a new clutch, including the hydraulics for the system is on the cards. Plus a dressing of the flywheel while I am it. The again - who knows how long ago the system was last overhauled?

    Yesterday I found some rust in the firewall driver's and passenger's side down low on the floor and side where it connects to the pillar that the door hinges fix to.

    Gee you just have to love these old cars!!! Get one thing sorted out and then something else calls for attention.

    Kind Regards
    Lionel

    G'day Dennis,

    Thanks for the insight into the linkages over on Garry Treen's thread. My 202 cubic inch motor was made in late 1977. When I bought the vehicle off the previous owner it had a carburettor fitted off a HR with a carburettor. that was originally fitted to a 161 cubic inch engine.

    The cable arrangement it came with is pretty dodgy. I will have a go at improving the cable system first. If it does not work out for the best I will investigate the mechanical linkage system.

    It will be after my getting a new clutch. Well once I remove the current one and work out which parts of the clutch for the engine conversion are Holden parts and Land Rover clutch and flywheel parts??? The fun of engine conversion vehicles.

    The research I have done in other threads leans heavily towards all Holden parts. However, some people do mention possible mixes between Holden and Land Rover or other English manufacturer's parts. If the parts do not have the nice words like "Holden" or "Land Rover" stamped on them I will be taking the old clutch parts down to the local Clutch and Brake place. There are some older gents there who should be able to accurately identify which parts I should be ordering.

    Taking the clutch out is the project for tomorrow. With the parts identified I hope to have the clutch and brakes sorted out in a couple of weeks. After that a new exhaust system .... then some rust in the body cut out and welded... then Do the leaf shackles .... then sew up some new upholstery for the seats .... then...

    Kind Regards
    Lionel

    HOPE THESE PHOTOS HELP

    Hi Lionel

    Hope these photos are what you were looking for. If not let me know and I can take some others.


    looks like they only put one bolt into bulkhead.
