Continuing saga of my miss-firing engine.
I have now covered well over 500 miles with the car since changing the plugs and she has never missed a beat. Oil pressure starts off about 45 LBS (classic 20/50 oil) dropping to 25LBS when she reaches normal running temperature and stays at that pressure at all speeds except idling when it drops to almost nothing. Touch the accelerator and she?s up to 25 LBS again.

Any observations, comments, suggestions, welcome.

Continuing saga of my miss-firing engine. 😀
Looking through some box?s of bits in my workshop the other evening I discovered 6 unused KLG P Ten 80 sparking plugs, these are the very spark plugs used by Lagonda in this engine. (I remembered buying them on e-bay a few years ago). My thoughts were these plugs should decide if it is faulty or wrong plugs I have been using that is causing the engine to fire on five cylinders. I set each plug to 22 thou, put them in the engine and started her up. Without a moment?s hesitation she fires on all cylinders, I then took her out on a five hours drive without the slightest problem. I?ve changed the oil and used one of the patented oil additive which are supposed to help with cleaning any carbon deposits that were remaining.
I have run her every day for the last week covering lots of miles and she has started first time and on all cylinders, I?m now starting to have a little more confidence in her. Let?s hope this has solved what was becoming a very irritating problem. :]

Unless the Gods of misfiring engines have other ideas!

Hi All I will take on board what everybody has said and go over the ignition side again. :}
Mark-Jim: She is a 190/1. I changed the old diss cap after discovering the cable screws holding the ignition cables into the top of the diss cap had melted welding the cable to the very TOP of the hole. When checking these seemed tight & secure but were in fact well away from the brass contacts, inconsequence the spark had to jump a great distance. I thought I?d discovered the problem after changing the cap for a NEW-OLD stock cap and she ran well for three days but as I said above Sunday back to five cylinders. My next move is to change the capacitor/points check the wiring to the coil maybe change the coil also. I?m very reluctant to put one of those new Holden diss cap?s on as I?ve had such bad reports as to their reliability but if need must so be it. > The saga continues

Hi All. After talking to various people over on the AMOC site (Aston 2-4 has the same engine) It would seem I?m using the wrong type of plug. They recommend NGK C6 HSA which is a hotter plug than the NGK C7 HSA (the plug I?m using) and is better suited for the standard engine. I have ordered a set of C6 HSA and will let the forum know how I get on. :]

Hi All Well the story continues! I changed all six plugs this evening, I cleaned up another set of six plugs and opened up the gap to thirty thousandth of an inch (for a cleaner burn) Put the clean plugs into the engine and without a moment?s hesitation she fired up on all cylinders. After worming her up, I have tried the old trick of spraying Redex directly into the carb?s intakes. I have run the car for an hour and she?s still on all cylinders. I thing I will have to take her out for a good long run after I do an oil change and see if I can clear the head, inlets and outlets of any residue carbon.
My understanding is that this engine is prone to fowling plugs? Any comments on this are welcome. The Plugs I am using are NGK C7HSA. What are others using? any comment re the type of Plug.
The car has been standing for twenty eight years but before she was put away the bottom end of the engine, the valves and other items had all been reworked including the head.

Thank you Peter for the reply. I have undertaken all that you suggest and when the engine runs it runs very well, it?s most perplexing!
I replaced the distributor cap with a new cap of the correct type and put new plugs in, the car fired up on all cylinders and run like a train for three days. I thought I have fixed the problem but when I went to start her up on Sunday, back to the five cylinders. I was so fed up I had to just walk away and haven?t been back to it yet so It may still be the BIG HAMMER!
One thing I have found is the earth strap from the bell housing to the firewall has come apart and needs to be replaced…. Question! Could a bad earth from the engine/gearbox to the firewall cause the engine to become intermittent?
It would seem that once I lose a cylinder it never returns without cleaning the plugs, the cleaning of the plug may be just my imagination who knows.
I intend to do a compression test which should resolve the sticking valve theory one way or the other. If it is a sticking valve why will the engine run so well over all speed ranges and never miss a beat (That is when it decides to run on all six cylinders).
I do have the flashing plug adaptors and they are all flashing which should mean the plugs are firing.
Any other suggestion/theories are most welcome.

Just a little frustrated!

Hi Mark and Jim. I intend to make a new earthing cable that attaches to the gearbox and continues down to the mounting bolts of the starter and make a good contact point on the bulkhead I will at the same time confirm the condition of other cables especially the one from the power cut off to earth if this is not the answer then it?s out with the starter motor and threaten it with a big hammer!! If that do?s not work hit it a bit harder Ops!! That comes from the days of Empire silly me!!

Hi Peter My first line of attack is to check over my earthing as my starter has always been lazy. I found this morning the earth bonding between the gearbox and the chassis has come apart.

Hi Peter why don?t you email these photos to a number of specialist companies and see what they have to say about possibility of repair. Most of the classic car mags have name and e-mail details of repair companies.

Hi Mark. Many thanks for that I was trying to tease out of those that know if there is an alternative set of needles to make the carb richer or if needed poorer but after off line discussions it would seem the needle you suggested is the correct one for these carb and to have the carb rich or poor is set within the tuning procedure. Yes we have a company here in the UK for SU bits for you information I have enclosed a link to the site with drawings of the carbs and parts in question.
