only had experience with aldon on the 1600 rorty Vit6 perfect for 10 years
current 2000 mk2 has lumenition optical and has been faultless since 2014
recent repairs to a spitfire had a failed 123 fitted with permanent earthed dizzy feed and fitted a accuspark to replace it which needed a new module after a days work
this was soon replaced by supplier but fit an old slave from a herald and that worked fine .
so quality looked good but didnt work well at all .
the idea that things fail under a hot bonnet has to be a bit of a myth most all work in the temperature range on normal driving (the fails will be down to a number of other things }
as for ballast many elec units work on a voltage range of 6 - 18v and with a ballasted feed on a poor battery it is easy to drop the coil voltage below the 6v
operation range it is generally accepted you need to drop/bypass the unit feed to a full 12v supply and use a 3 ohm coil ( the ballasted one is 1.5ohms
and if fed with 12v will double the HT blow rotors and fail dizzy caps and the higher current will blow leccy modules and burn points
they do need to be matched and not mixed ,

a worn jet would be richer as the hole bore becomes larger , adjusting does compensate a bit the start of all needles is the same diameter
so winding the jet upwards when the bore is worn makes up for the problem in way generally to be quite workable but not utopia .
biased needles wear the jet as they rub the side of the jet bore hole
if you have a depth gauge use it to measure the height of the jet in the carb throat get both the same and adjust from there for best running idle
if you have lifting pins just touchy feely contact with the air piston and lift a couple of mm
if it faulters a few rpm its lean if it raises the idle a few rpm its rich if nowt happens its about right
you are looking/listening for a hint of change nothing radical
never do this with the cleaners off thats just a waste of time

A bit annoying to have a problem so soon after buying the car but I have learnt a lot already!
the joys of getting to know your classic
we have all been there

any wax plug goes out of spec after some years thermostats are the same
they are easy to change so a wax stat with the 2p mod will remain reliable , ie there is nothing left to fail
only if the needle has worn the jet orifice.

Is there a better solution, other than replacement Waxstat jets?
not really a 2p mod to waxstats is fine but if its bent then its where from here ???
the rods/levers in the kit sold by the many as a replacement are pretty hopeless

if you buy the silly priced wax stat conversion i can assure you half of it wont fit the linkage will jam and you will be worse off than when you started all this

check the idle stop setting any variance with air flow through the carb will alter the rise heights of the air pistons
i have a simple gauge that you can set the throttle balance by measuring the air piston lift
which is just another spin on how to balance a crude bit of kit
in their day they were just preset with a fixed idle screw amount and bunged on the engine no faffing about with balancers of any sort were rarely ever used
on production. air flowed control was not devised till the late 80s up till then 1.5 turns on the idle screw was all it took

its quite common for the jet tube to b a bit too long and this jams the choke /jet return but these are old jets should be ok as long as the tube is
not kinked under the spiral protection .
many fit new and have to trim 3mm off the tube
and often spare 0 rings /olives are found stuck down the tube hole

the small hole in the cap it to allow atmospheric pressure changes from not making leaks when left staic
only of use in sealed/semi seal breathers
of no consequence when used with open breathers like the herald of the day
the alloy cover is better at reducing tappet noise and mayo /condensation problems so just fit a small filter as you have (keep it clean ) or just tube the fumes to below the engine zone its simple and get some sleep , its not something you need to worry about

and when they stick it holds the jet down in its rich position and often wont spring back
to its adjusting nut stop till you give it a poke with your pinky !!!

with all the torque testing we did on truck production we found spring washers were a waste of time and they were
dropped from all specifications back in the mid 70s
replaced with plain washer and plain nut was the most reliable many locking nuts were also dropped

agree E5 only for factory performance not mower fuel .
this has the ring of dreaded rubber slivers , bits of hose get sliced off when inserting the metal fuel pipes
they float around and jam the back of the float needle valve crafty little sods .
one thing you will read about on here is the 2ltr engine crank pulley damper ring has the timing marks these
break down the damper bonding and the ring can move this is a bit out the box but it happens
so one day you need to confirm TDC on No1 is as the marks show .
i dont like HS6 on the 2 ltr there are no real specifications for that set up
high idles can be leaks in what ever breather system is fitted including rocker cover gaskets and filler caps
i would replace the hoses with gates barricade (its tough stuff) and flush (pump ) out some fuel into a jar
remove the float valves see if you catch some tiddlers as a first move
to check for air leaks you can use a pump oil can or old trigger bottle use engine oil brake cleaner or petrol(it wont catch fire ) spray around the gaskets see if it gets sucked in

looks like the wax stat base of jet seems bent ???

just suggested fit hose to the rocker spout and breath it to atmosphere with a length of hose

my first years apprentice wage in 1962 was £2 9s 3d a week you were lucky and .....rich

in 64 i was in 2nd year of my 5 yr apprenticeship and probably on the dizzy wage of around £5 a week
my first new car was a series 2 super Imp in 68 at £462 and probably on around £1300 as just made Foreman of Quality Engineering (previously central investigation dept ) and out on road test with CID on your overalls would clear a transport cafe in minutes
and deemed to be the youngest foreman in Rootes group
happy memories

i tried to imagine you in one of those ....and failed

is there any royalties on the kit design Ha !!!

LNM 169 Mk5 Hillman Minx was bought in 1964 for £65
she was bright red ( in fact fire engine red painted at the airport )
we fitted a head from a Sunbeam racer had twin 1.5" copper exhaust and washers under the valve springs and a silly carburettor
off the sunbeam .
skimmed the head in the Apprentice school and with a add on must have rev counter pulled over 7k
used to shear crown wheel bolts and half shafts if took off too quick for an old long stroke side valve she flew
just take third gear and open the taps you were king of the road
Happy days when she needed some under frame welding my uncle who ran Rootes parts sent a complete side rail
down from B' ham and i never got the bill

Paul next time you are round here lets run her over the tracking gear
going light is more down to the lift from the lack of down force upsetting the static toe in
back to checking with 150 lb on each seat ( or just we use rent a crowd
i could take the kit to the Pub on monday ????

you could just remove the small filter and add a length of hose to breather lower below the engine
there is an advantage with an alloy cover in that it takes on engine heat and doesnt get cooled by the fan so it is far less likely to generate hair cream/mayo
that you will get with a tin cover and short runs

HS4 Jet issue
in Fuel System
Posted
the 1500 is designed to run on the leaner side of whatever, hence they use a 88c thermostat etc as the car is in the beginning's of the emission control era.
i would expect on a fast cruise the colour will be lighter .
think you need to stop checking and do more driving Ha !
finding just what needle and spring is fitted will be a good call .
