This is our 1952 Jowett Javelin
Owned for many years - the engine had just been rebuilt when I purchased it and I have covered over 20,000 miles in it since
Powered by Jowett's own 4 cylinder horizontally opposed / boxer - 1500cc engine - note that the radiator sits to the rear of the engine bay (over the top of the bell housing)
This was the first all new / clean sheet design production car after the end of the second world war - Of independent manufacture Jowett never followed the same route that the other manufactures took - most of which returned to churning out the same design of separate chassis / bodied cars that they had been producing prior to the outbreak of war. The Javelin for its era was cutting edge design - all round torsion bar suspension on a bodyshell of unitary construction - the worlds first production car with curved glass windscreens for both the front & rear screens along with a very low drag co-efficiency in the low 30's (all done by design - Jowett did not have access to wind tunnel technology in those days)
The car is well a well loved member of our little fleet and carries the business crest of my late stepfathers taxi business (he owned one in the early 60's)
Much more to follow on this remarkable little car and it's journey's

The car has stared / made up part of the Goodwood Revival period taxi fleet for every year that I have owned it
Here's myself and my lovely other half Sharon at Revival in 2019 - sadly no Revival this year due to the pandemic (we would have been there now had this not been the case)
Sharon is a costumer in the film, theatre & television industry - hence she take the period dress theme for the event very seriously and the little Javelin gets packed with her costume changes for the event
Don't want it to appear that I'm wishing my life away - but roll on Goodwood Revival 2021
Great cars so advanced for there time, am I correct in saying that they are one of the few cars that went along the production line upside down only turned up the correct way near the end of build? I have got so close to owning one on a few occasions, I remember going with my older brother to view one which would have been his first car. Our ultra conservative dad stopped him buying it at the time as he said they were to radical. He ended up with a Vauxhall, what a shame.

Absolutely correct with the production line set up - Jowett had Briggs Motor Bodies at Doncaster produce the bodyshell - which arrived at the factory painted and part trimmed ready for Jowett to install the drive train & suspension
And now we have the new image uploader sorted we might as well have a pic

The Javelin normally gets squirrelled away in the barn around October time every year - I don't do anything special to it other than make sure the antifreeze is of sufficient strength & remove the battery - It then gets unearthed in March - cleaned up & serviced ready for the year - last year was very different and the Javelin stopped in the barn - with the chance of things now starting ease out of what we all hope is a final lockdown period I decided to go & retrieve it from the barn
I quite like the patina of the the car - it gets used and its representative of what it would have been at 10 - 15 years old - I don't bother with a cover - the air circulates around the barn and keeps everything dry - but the car has now been in there 18 months and its come out looking somewhat filthy - loaded to the trailer and back to the workshop
Washed off and then into the workshop
Goodwood Revival 2019 was when I last used the car !!
Residue has formed on the chrome work but it polishes straight off with little effort
Fitted the new choke & bonnet cables (they reused the original knobs as these are no longer available)
Primed the fuel & fitted a freshly charged battery but it wouldn't start - cleaned the distributor cap up & fitted a new set of plugs
Found a dead suppression cap - replaced with a temporary for now but I have a new cap & leads to build for it - Just wanted to get it running first eventually fired and ran for a short period then died - some further checking reveals that the chokes are not operating fully - time was getting on so I have left it for today and will have another look at it tomorrow
Sid thought he would pop in to check up on what I was up to and have a quick look at the new project on the lift (MGB GT) which he's taken a liking to

I fabricated a new bracket to retain the cable outer for the choke
Although simple in plan the choke linkage is a pain to access which runs across the rear of the radiator (which sits at the rear of the engine) - the horizontal rod is actuated by the cable
To which the rods that connect to the carbs link back to
Something that should be easy but its a pain
Managed to get the engine started but it wont run below half choke - it just dies - probably weak / stale fuel - something I need to look at when I have more time - but the clutch plate has also seized - it sometimes does when left for longer periods and quick run with the rear wheels off the floor and a few dabs of the the clutch pedal normally sorts it - but not this time - again something else for me to investigate further when I have a little more time
Yep, carbs really hate standing with modern fuel in them, and plugs seem to suffer routinely if fired up on the stale stuff, so probably worth changing them too
The last time i was near a clutch freeing excercise was a little hairy. Picture a pre-raced 2.8 mk2 granada balanced on its diff on nothing more than a 1 ton halfords trolly jack , facing a granite barn in an enclosed courtyard , howling and sat at an indicated 140 in top! It took a lot of persuading but eventually it freed off like a good 'un! Happy days.

Good luck and keep us posted!
Already changed the plugs - they tend to suffer anyway as they sit in recesses within the head that then hold water so I tend to change them at start of every year - heard some horror stories from other owners with plugs changed at several thousand miles but they have been in 4 + years and over that period seized in the head - I'll drain the fuel tank today and replenish with fresh and see how I get on

I tend to do the same trolley jack trick and then dab the clutch sharply and it normally releases itself - not this time though - I'll give it another go later today - if it doesn't go there's a inspection plate that allows quite a lot access on the underside of the bellhousing

Many years ago my uncle had a Mk3 Cortina and after he passed away it lay in the garage for some time. Eventually my aunt (who did not drive) asked me to get it sold. The clutch had seized on it and in the end I had to let it run up to temperature, pushed it onto the road, started it in gear and drove it for about half a mile with the clutch pedal depressed and jumping on and off the throttle. Came off with a bang and was fine after that.

Progress has now yielded some results - Fuel tank drained & refilled with fresh fuel
I removed the leads & cap which were goosed & built a new set up
And now have the engine running very sweetly
That just left the seized clutch which wouldn't respond to my usual methods of rear wheels raised off the floor and starting the car in gear then running it with the clutch operated several times until it became free
With removal of the cover you can pretty much access half of the clutch / flywheel assembly - With a few of the pressure plate bolts removed you can carefully slide a thin bladed scraper between the clutch plate & flywheel - replace the bolts then turn the assembly to do likewise with the next section - literally a 10 minute fix and its back driving under its own motive power - Several other things on the list to attend to now - it needs a lubrication service / grease up and the car requires a clean up of the paint & chrome - but at least its back up & running
Don't you have a small hole on the top edge of the rib on the bulkhead which is where the choke outer cable should be secured with a pipe clip?
Not on mine no, and to date the ones that I have found on other Javelins fitted like this are simply not that effective - from experience it leaves too much of the inner cable exposed for it to operate correctly - I've found many differences in the fitment of the choke cable over the years and I tend to end up making some type of a bracket to get the cable to operate correctly

Rather than a single cable plus complex linkage would it not make life easier to fab a little bracket to run 2 cables from the knob - one to each carb? Much simpler surely?

Had a brief look at the Javelin today
The waterproof suppression caps that I had on order turned up hence these were fitted - pretty critical on the Javelins flat four engine - the plugs render themselves to water spray due the the proximity of the road wheels in wet weather
Then gave the car a run up for 30 mins or so - hopefully I will find sometime in the week to give it a good clean up & make it presentable
Looks nice and neat! Got Ms Triss out today (Midget) she was very very unhappy for about 1/2 a kilometer and then burst back into life - I think she really wants an Italian tuneup.

Several weeks have gone by and the clean up has yet to commence - better get to it then
One of the main points was to sort the front grille out
The alloy fins had oxidized over the period that the car has been stood
I removed each fin individually and set to with the polishing wheel
Then reassembled the grille
Now looking a lot smarter
The rest of the chrome was given a polish up too whilst the rest of the car treated to a mini valet - I still have some small areas of paint to touch in and a service to undertake at some stage over the next week has there's at least one longish trip imminently on the cards in August
