  1. One thing to think about is that seat runners will raise your seat about 1 inch.

    It does not sound much but put some packing on the seat and evaluate the view through the windscreen, where is the top rail? The screen can be raised but any hood will then also need adjusting.

    As someone the looks out through the top of the windscreen I am aware of it when driving. I have run out of adjustment.

     

    Also what car do you have as that can change advice.

  2. Reminds me of the Morris Minor master cylinder. Fitted in chassis section from on top and bolted through from underneath  then the front torsion bar fitted across the bolt heads  blocking in the bolts. And that was done in the factory to every production car.

  3. My experience of sikaflex is that it does not age.

    I have some that was applied 30+ years ago and still a solid joint.

    If it has come adrift my guess is that the surfaces were not de-greased properly or that the sikaflex was very old stock. It has a limited shelf life before applying.

    I don't see a bell-housing to join the engine and gearbox in the pics.

    The Zetec engine will require an ECU and things like a water rail as it is designed the the cooling connections at opposite ends of the engine. Have you got the engine mounts to fit it in a for aft orientation?

    It looks like you have a fun project and with some work and head scratching you should end up with a fun car.

  4. Coils can gradually die.

    They are essentially transformers and work on change in electrical currant.

    They have a few turns of wire between the + and - connections this is the primary of the transformer and a lot 10000+ more turns of finer wire as the secondary. The secondary and primary share a common connection the other secondary connection is the top of the coil where several thousand volts appears.

    The wires ( primary and secondary ) are solid copper insulated with varnish. The secondary has to be wound carefully to prevent overloading the varnish insulation.

    The current in the primary builds slowly because it is creating a magnetic field. The current in the primary is stopped causing  a large voltage in the secondary and a spark in the plug as the magnetic field collapses.

    Creating the magnetic field also puts a force on the wires (magnets attract or repel) this tries to move the wires so that the rub against each other removing some of the varnish insulation. Sparks (or worse shorts) appear taking the energy intended for the spark and generating heat in the coil. The assembly should be impregnated with insulating material (like epoxy) to prevent this but bubbles can be left allowing a gradual degeneration of the insulation in the bubbles. This has little effect on the DC measured resistance of the coil but measuring the inductance will show it up. Unfortunately few electrical multi meters measure inductance.

    The best test is to substitute a known good coil, sorry if I have been too wordy.

  5. When you say you get a spark out of the king lead is this lead to engine block or have you put a spark plug in the end of the king lead and touched the plug body to the block?

    The latter requires a higher voltage to create a spark and this is what the engine sees.

     

  6. As the design was done in Germany I tried to come up with a German word for ratio that began with i but failed.

    The Ford wiring colour letters make sense when you realise that the wireing was designed in Germany.

  7. My reaction is that Richard Stewart used whatever parts he could get cheaply. So there was no standard seat. He would buy end of lines and adapt the kit to suit, adapting again when the current end of line ran out and another different one was found.

    Second previous owners could have changed the seat.

    So You say that there are studs in the seat. So if the external nuts are loose then trying to move the studs will tell you if they go into captive nuts or loose nuts or even if they are welded in studs.

  8. The series 111 (roman 3) had a couple of front suspension setups during its production life.

    The main ones were either onboard or outboard.

    The inboard ones had coilovers just behind the nose cone. The outboard ones had them out in the open between the bodywork and the wheel.

    The suspension mounting points were not the same so you would require some fabrication to change over.

    With a bit of luck there will be cars with both types at the national kitcar show Malvern where you could compare them.

  9. The monocoque chassis kits were also available in zintec steel which is a zinc plated mild steel. Etch primer then paint of your choice or even wrap the car. Use a good mask when sanding down.

    Some very early kits used a 1 inch rectangular steel space frame chassis.

    Most people run 18 to 20 psi in the tyres. As the cars are fairly evenly balanced front to back the same  psi all round.

  10. Main problem with mechanical pumps is leaks in the fuel lines / connections. Though I have had hardened valves in the pump causing failure once.

    After a longish time the petrol in the carb can evaporate  causing long cranking times. Try priming the carb by using an old washing up liquid bottle with some petrol in it and connect it to the carb inlet with a short hose and squeezing some  petrol direct into the carb, its a long time since I last did this but it does show if petrol starvation is the problem.
