Floyd Brothers 70 Challenger

One for over a beer, I reckon.

[Dave999]

did a search on holley rebuild kit, what is that small disc?
found loads of pictures of kits with that small disc
no lables or parts list though

Mmmm curious


second picture here seems to imply that it goes with the parts illustrated in the pic

I know, it’s odd, eh!?

No note of it in the kit exploded diagrams list either. I didn’t see where the used one fell from, but it’s clearly been clamped against something. I’ve been wracking my brains for what I was doing when it fell out. I have a sneaking suspicion it was when I turned it upside down after removing the discharge needle, but can’t see as it would have come from there.

That’s the baggie it came out of, but still don’t know what the little square cork ones are, either.

Nowt to do with the power valve, but oddly that does seem to be the sort of shape that is pressed into it.

[Dave999]

i wonder if it sits under a spring or in the base of a hole. stops a spring galling the ally body or stops the middle section of something rattling againts the body?????

thus has potential to fall out when you least expect it, and can't see where it come from, but would have no real impact if it was missing


Mm

[Stu]

That’s a very fair suggestion.

Any idea what the little square cork ones are?

[Dave999]

no idea but you'd expect them to fit in little square sections around a stud or pipe or passage i'm thinking air passage rather than fuel in this case, foams and corks, and modern fuel doesn't fit i.e mix, well, in my mind. you'd use a modern plastic/rubber if exposed to fuel.

when clamped between 2 halves they'd seel that stud or passage so it didnt leak around the join

it might be a case of really old carb uses cork
more modern uses a better standard gasket and doesn't have space place or hole for cork

similar to a really old engine uses a rope seal and a newer one uses a modern synthetic rubber type seal at the rear of the crank. Mopar gasket kits have neither and you buy separtely, probably for this reason

it will be universal kit. probably covers carbs from 50s to present day.

used to really annoy me when i purchased a VW flat four gasket set. it covered 3 series of engines vintage 1950s magnesium, 60s single port and 70s/80s/90s twin port aluminium cases, with their differing oil coolers oil pumps and pushrod tubes

i.e you'd get 3 versions of some parts 2 of others and 1 of a few others covering 1200 1300 1500 1600 with no idication which fitted more went in the bin or draw of "less than useful" than was used on the motor, uisng the wrong bit would crack the oil cooler mount and the engine case would be scrap....

i.e if its a struggle to fit it, it pobablky aint the right part for your carb "series" and can go in the "Draw of less than useful stuff"


Dave

[Dave999]

the only other time ive seen the corky stuff is standard rocker cover gaskets

i.e keep hot oil in provided you don't do the bolts up too tight and compress the life out of them.
designed to allow differing rates of expansion, some movement, and still maintain some kind of seal for something that is at atmospheric pressure and is sloshing about. engine case and top end is vented so the rocker cover gasket sees much the same pressure both sides or at least PCV working ever so slightly lower on the wet side

you don't have oil in a carb and most of the buiness end is not at atmospheric pressure, most of the internals will see vacuum considerably higher than a PCV can create in a big old engine case....

I'll guess at, for some kind or air passge above the water line as it were.... open to atmospheare at one end and the vacuum seen at the blow or venturi at the other but potentially not on this version or series of your carb model. you'd have some grotty ones to take out if they were

I notice there’s gaskets for an electric choke, might be part of that. These kits service more than one model of carb so you always end up with parts you don’t need.

[Stu]

Yes, wasn’t worried about the leftovers in general, it’s just the fact that pesky little disc fell out of somewhere that’s narked me.

Anyway, gaskets and diaphragm should be here on Thursday, as well as a jet tool, as I may have slightly chewed one up with my big flat blade…

In better news, this turned up today and is bloody brilliant! Far, far clearer than any of the official Holley books I’ve seen and the one I had. Just a shame it didn’t turn up until I’d done most of it.

[Stu]

In other news, postie just delivered something I’ve been looking forward to getting. I can finally look to get rid of the dodgy rear indicators that someone bolted onto the bottom of the rear overiders. They look like bowlacks dangling off the bottom of the car…

Always hated them, these should look nice and stock once I figure out how to fix them to the inside of the lenses.

[Dave81]

Good progress mate!

[Blue]

Be good to get rid of those 'orrible indicators! Personally I'd just put the lights back to American spec. but I'm a bit like that..

[Stu]

Lol, I’d have had money on you saying that!

I did consider it, but I use it a lot on the road and decided I’d rather not bank on the average Joe realising my brake lights were flashing because I was turning. It’s a self / car preservation thing for me.

I’m focussing on critical stuff first, but 3 things about the view from the rear really annoy me :

1. The bawbag rear indicators - hoping an easy fix now!
2. The view through the rear window of the torn up back of the rear seat - away being fixed by a local upholsterer.
3. The wonky lights where it’s clearly had a push at some point - bodywork is a bit beyond me, so got a friend locally who’s going to come and have a look and advise.

If I can get those three sorted in the next few weeks, I’ll be a very happy man. In the meantime, I’ll keep chipping away.

I’m assured that the yellow LED installation is pretty straight forward, but hadn’t really considered exactly how I’m going to fix the panels inside the rear lenses…

[Pete]

LED Flashers.

I would mock up first before any changes and check that the Indicator relay will still work using LED's - they don't draw much / any Current so the Bi-metallic Flasher Relay may not work... you may have to add a resistor or two to make it function.....
