The 'E' Type Forum

Continuing my investigation into whether my clutch master cylinder has enough travel (as my clevis fork was ovaled through decades of use), I would be really grateful if one (or better still two or three) forum members could measure the distance from the clutch pedal rubber face (where your foot pre...

If I adjust for proper free play I have 1/4 inch off floor before transmission is engaged.

Thank you so much.
My measurement is 1/2 inch
I will get clevis fork redone

Many thanks

Vancouver!

I just rebuilt my 1969 all synchro transmission because the clutch master cylinder clevis fork hole was worn massively oval meaning that my clutch pedal at rest was too close to the floor. This meant that when my clutch pedal was pressed, the clutch was not disengaging enough. The synchros wore out ...

I will take my series transmission out for rebuild as my first gear synchro wore out as the clutch was not disengaging completely But I wish to fix another problem which is that when I am in third gear and apply power, the gearshift lever moves forward. When I take off power, it moves back. I have d...

I have tried idle speeds between 800 and 1000 rpm and the problem is still there. The mixture also varies when one goes above idle as I have had both a colourtune and an air fuel ratio meter on the engine. At idle the mixture will vary from about 11 to 1 up to 14 to 1 whilt while driving it varies, ...

I have replaced all the ignition components and took the distributor out looking to see if the bearing was worn which would cause varying timing. I did this even though the ignition timing was unwavering at the idle when looking at the timing mark. I did discover that the distributor sliding plate (...

The problem is there both with and without aircleaner....

I did put brand new UMs in it and also tried UE needles and problem is still there.

Thanks for the charts. I just checked the piston spring force at the specified length by compressing them against our kitchen gram scale to the correct length (as drawn on a vertical piece of paper.) All are plus or minus 5 grams to the 128 gram spec at roughly 3.875 inches. My wife was not pleased ...

Hi David, I very much appreciate you taking the time to think about my problem. I redid the SUs myself. I have worked on these for 40 years! Replaced throttle discs (and centred them using a light source behind them to make sure they are even), spindle seals, jets, needles, floats, float needles, id...

I am pretty convinced it is a fuelling issue. There is play on the levers before the throttles start to open the throttles. The mixture is also varying when on the road as evidenced by the air fuel ratio meter I have hooked up and I think it is independent of engine mounts and linkage. But the rpm i...

Hi Christopher,

Thanks for your ideas. I have checked the timing and advanced it until I get knocking and backed it off so I am sure it is correct.

Compression is good. Valve clearance not checked but I figure it must be good. vacuum text shows no sticking valves.

I took the cam covers off and checked the timing. The cams are standard. The fuel pump is a standard SU and I have replaced all its parts.

If I fill the float bowls with gas, let the car idle and turn off the pump, the splashy misfire still occurs

Dennis

I have done it before. It is just two bolts but I suggest you not do it until you have the two new rubber seals that will need to be replaced when you split it.

I used some locktite when I put them back together.

Dennis

Hi David,

The carbs totally redone with o-rig spindle seals, new floats, needle valves, needles, jets, idle screw seal, throttle butterflies etc.
The piston drop times are all within spec.

Dennis

Hi David, I have looked for air leaks as follows. Manifold off, pressure tested and surfaced. Reinstalled with petro-proof sealant between manifold and head. Plug brake booster and distributor advance take offs, new carb to manifold gaskets. Intake manifold vacuum is steady, not varying. Rubber o-ri...

I have put rubber o-rings on the throttle spindles as the cork seals do not last. I have played with the float levels in various positions with no luck, needles are flush in the pistons. I can set the mixture with my air/fuel meter and if i set it at 13.5 to 1, the exhaust note is splashy and the me...

I have a splashy idle with the odd intermittent lean misfires on triple SUs. Using colourtune or an air fuel ratio meter, it shows the mixture is not stable and is varying. The mixture varies more at idle and less at speed. It seems to be more splashy when warm and occurs on all cylinders. I have do...
