Stromberg 97 and Secrets of Speed Scalded Dog Manifold Upgrade for the 1929 Model A Ford Sport Coupe

Some time ago before my Dad passed away we had chatted about what upgrades might have been done to the coupe back in his days. He was born in 1936. Before I managed to get the parts my Dad sadly passed away.

So as a bit of a tribute I bought the following parts


Stromberg 97 Carb – from Dave O’Neil (O’Neill Vintage Ford)
Scalded Dog Manifold – from Charlie Yapp (Secrets of Speed)
Chrome Air Scoop – from Dave O’Neil (O’Neill Vintage Ford)
Facet Electric Fuel Pump – Carbuilder.com
Petrol King Fuel Pressure Regulator – Carbuilder.com

Fuel Pressure Gauge – Carbuilder.com
Braided Fuel Line – Carbuilder.com
Copper Fuel Line – Amazon
Rubber Fuel Pipe – Carbuilder.com
Various Connections and Unions
Jubilee Clips -Screwfix
Fuel Pump Relay – eBay
Rocker Switch – eBay


Parts I already had


MSD plug lead set and tool
Modern distributor cap
Wire and connectors

My friend Austen fabricated the required new throttle link rod from the dimensions provided by Charlie

First job is to remove the existing manifold and carburetor

This is a Model B carburetor fitted by a previous owner, this carb has had a brazed repair in the body which whilst a bit rough and ready worked fine.

These inlet manifold fixing bolt holes where not used with the original manifold, but are needed for the new one. These were cleaned out with a tap.

The carburetor and manifold were assembled and bolted into place

First attempt at wiring the fuel pump and the use of braided fuel line. This looked quite bad as the wiring was temporary to get home from my friends workshop. I didn’t like the look of the braided line.

Decided to go with copper fuel line with rubber termination to solve any issues with engine movement that may cause leaks.

The fuel pump and regulator fit nicely in the chassis rail, these were removed to change 90 degree elbows for a better pipe run

First attempt with copper/rubber fuel pipe as you can see the wiring is a lot tidier, you can also see the pipe run between the pump and the regulator. The wiring will be tidied and weatherproofed further. Use of the screwed connector has been chosen to make a pump change on the road easier.

This is a view from above, quite tidy but still not happy! Too much pipe run above the exhaust manifold and the carb feed pipe is not secured enough for my liking.

At this point a leak from the sediment trap was noticed, caused by the failure of the gasket

The reproduction item is made of neoprene but a horrible fit and had to be cut to fit. Bowl and trap were cleaned and then reassembled

Wasn’t happy with the throttle feel so spaced with some fibre washers, a lot better now. The throttle also stuck a little, so the joints on the rods were lubricated and Clive at Stromberg provided a nifty little solution to snap the throttle shut. This also doubled as a safety measure as per Charlie’s advice in case of linkage failure.

As you can see runs very well, starts better, warms up quicker, very happy.

More once I get a few trips under my belt with the new set up.

Back to the Future (well kinda :)) Part 1

Advertisements

After the breakdown on the way to Wheels Day 2017 and some diagnosis the Pertronix module was the culprit (well the symptom anyway :))

This is the second module failure, so it’s back to points which as least can be fixed on the road. I’ve gone for the “modern points” setup by Nu-Rex, “modern” is pretty amusing as the new plate contains the 1957 onward Ford V8 points as opposed to the original 1929 setup.

Before I began I set the timing to TDC via the timing pin as per usual on the Model A I then started to remove the Pertronix system

During removal I found that the lower distributor plate had been deleted, a bit annoying as I’d ordered the upper plate from O’Neills. Luckily John Cochran had a used item I could use (thanks John :))

I’d also ordered the recommended longer pigtail for the lower plate, this is recommended to alleviate the stress on the original which is a little short and often fails due to fatigue. So after desoldering and drilling the old pigtail was removed. Then it was a matter of a little cleaning and soldering to get the new item fitted. As my car has no pop out ignition switch I further modified the plate to securely fix the hot cable to the plate by drilling the dimple which was designed to contact the original pop out switch.

Once all the modifications were completed I installed the plate into the distributor.

Lower plate installed

The pigtail was connected to the points contact ensuring that the connector was not able to accidentally ground to the distributor housing.

Also checked that the timing advance lever was in the fully retarded setting at this point

Next the upper plate was installed taking care to wrap the pigtail around the cam spring whilst making sure not to pinch the cable.

The upper plate will only install one way into the tabs and groove and should turn freely.

Nu-Rex Modern Points Upper Plate Installed

See the next episode for rewiring, points adjustment, timing and hopefully an engine start.

Looks like she’s dead Jim…

A day after the trauma of the breakdown on the way to Wheels Day, the investigation began!

Still refusing to start and having no spark I decided to swap in a known good coil, lo and behold the car started and I was able to reverse out of the garage having to push in the day before.

After letting the car idle for about 10 mins it decided to cut out and refused to restart.

Knowing that the Pertronix is very sensitive to correct voltage I decided to charge the battery, however the car still failed to start and still had little or no spark.

So the decision to go back to points is confirmed and the parts are on order from O’Neills

Alternator Update

Advertisements

As mentioned in my previous Alternator post I called Nu Rex in the States and they were very friendly and helpful.

They advised that I’d have to split the Alternator to be able to tighten the belt pulley which in turn locks the fan pulley in place. It’s apparently very rare for one of the pulleys to come loose. I’m wondering if the clearly incorrect fan belt was part of the issue?

Nu Rex advised that the centre of the belt pulley should not be shiny if the belt is the correct item or not worn out,  as you can see we were wide of the mark on both counts!

I was also advised that the standard Model A Fan Belt is the correct item, and also to re black the pulley with a marker, which once it becomes shiny again will indicate belt change time.

Popped up to Simon’s and both he and his Dad gave me a hand to tighten the pulley and also lent me a piece of welding rod to lock the brushes in place to allow reassembly of the unit.

Correct fan belt was ordered and has been delivered from the ever reliable O’Neill’s Vintage Ford

Weather permitting I can get the unit refitted tomorrow

I’d like to get back mobile as there is a car rally/breakfast event at the nearby Wellington Country Park Farm Shop on the 11th September.

 

Kill Switch

Finally got around to fitting the kill switch on the Model A. With a car this old it’s nice to be able to kill the electrics when parked in the garage, this saves lifting the floor boards each time to disconnect the battery. Nifty bracket from O’Neill Vintage Ford which utilises the starter bolt, vintage style kill switch courtesy of eBay.
