    Carb tuning

    I have just rebuilt my HS4 Carburetors, what is the best way to tune them? I have the jets, level with the bridge, I've watched you tube videos but all seem to tune them different ways. Steve

    I had a fuel leak from a split in the jet tube sleeve, so bought a complete rebuild kit

    The car came with K&N air filters on it, I have just changed my standard exhaust to a bell twin pipe exhaust which has a branch manifold.

    I have just checked the new needle code number and the are ABT the old needle code is AAR will this cause a problem? also is this collar for the needle supposed to have this lip on the top? Sorry about all the questions but I'm new to the classic car world

    My needles have springs on them, so shouldn’t they centre themselves?

    Help needed, I have just rebuilt my twin HS4 carbs, on one of them if I manually lift the piston, it wont drop down back onto the bridge, the other piston will, any ideas what i have done wrong? Steve

    Engine bay

    My engine bay needs a good cleaning up before i paint it, and the engine block, the engine bay seems to have like an under seal all over it, is there anything i can use to remove it? Steve

    Carburetor

    Merry Christmas everyone, I presume that the carburetors on my 1975 spitfire 1500 are the HS4 type, is there any markings on the carburetors that will tell me?, the only number I can find is this one. Thanks

    Exhaust Manifold

    Fitting a new exhaust this week with a branch manifold, should i use the gasket that comes with it or I’m better using gasket sealer? Also should i use Exhaust paste for the joints on the Exhaust

    Coil

    If it’s not going to cause a problem, I will leave it as it is, it’s the electrics I’m more worried about

    Coil

    The control cable is still attached to the valve, I will see if it still works tomorrow

    Coil

    I take it I just need to separate these 2 pipes and reconnect them to the Valve, why would someone bypass the valve?

    Coil

    The wiring seems to be a mess
  20. stebec

    Coil

    Everything works ok, but a lot of the wires seem very brittle, think for peace of mind I’d be safer with new wiring. Have you any idea how I can get the electronic ignition wired up? Because with 2 wires already coming off the + side of the coil, there is nowhere to connect to

    Coil

    Think I might invest in a new wiring loom

    Coil

    Hi Johnny, I’m going to fit a new radiator on next week, so coolant not a problem. The wire you mention, I’ve not got a clue what it’s for, there is some very strange wiring on this car, there is even a wire attached to the earth on the battery.

    Is it an easy fix for the heater?
