Sieg SC3 7x16 Mini Lathe Question...

[GrifterGuru]

The problem now is finding any good pots for the older vehicles. There’s not much of anything out there for a car 20 years old or older. That’s not just cheap junk. You used to be able to buy new old stock, but that’s getting expensive and hotter to find.

I’ve been working on cars for 30 years. I can’t remember a time where I never thought. Holy crap they make this any worse. I’m not gonna sit here and say cars were built better back then but the over complication of the new cause is ridiculous. Especially with all the electronic module integration. Will one module that goes bad or short out can affect the entire vehicle it’s just off. I’m not sure what the big changes and wiring, but I see a lot more corrosion than I used to and wires and wire connections. And to add a few other things, we have a lot of low-voltage systems even more problematic. It’s a mess. It really is and the cost of some of this stuff to replace it is ridiculous.

Although I consider this a luxury and a creature comfort. I’m working on a 2014 maxima and the lady wants her climate control seat to work. Well, the little heater that heats up the seat shorted out and burnt out, climate controlled seat module, which turned burnt out the fan and suspect of the heater that’s seat, not including the labor or any diagnostic time priced out 1600 bucks

Kinda the point I was making. Overcomplication, reliance on electronics to a mechanical job and additions that just make no sense (heated seats for one, never could understand that as climate controls (heater) plus body heat makes seats warm. I understand the need for A/C and, potentially,
EFI but even then, I find EFI a stretch on a 4 pot engine. Give me a set of carbs any day over EFI. At least carbs can be rebuild and tuned at home wiithout requiring a degree in computing.

A few of my dads quotes growing up ( Im 52)
“New Means Nothing”
“ Thats gonna hurt”
“Pain and suffering is a great teacher”
Maybe not “his” quotes but learned a lot….
There where many more.

"Never risk what you can not afford to lose" is one I learnt from both my grandfather and late step father.

I have to sing the praises of EFI. My 97 Jeep Cherokee has it and I've been driving it for 20 years; it runs as nice as when
I bought it in 2003. Would not want to go back to a carburetor, at least on that vehicle.

And how much is EFI to repair over a rebuilding a set of carbs on a 4 pot engine? too much and too much time and hassle.

I grant that EFI makes tuning easier and fueling more efficient, but even so, correctly tuned and set carbs do the job perfectly fine.

the point is that yes you can tune a set of cards to come close to what EFI can do, but it is a 1/2 time job keeping it "in tune" the EFI system will adjust to conditions/wear and can be dead reliable for 200k miles. you will never get that from carbs/points/rotor caps etc.

in the good old days you never considered a used car with over 90k miles and most of the time the pistons were swapping holes at that point.

I owned a '77 VW Rabbit that used a mechanical fuel injection system and it was very reliable. I put almost 400K miles on it. Granted, the first 125K were on the first engine, but that's mostly because I found a drop-in replacement (from a VW truck of the same vintage) with a bit more displacement. I had a lot of fun with that car. Lightweight chassis, high-revving engine, GTI camshaft, oversized valves, sway bars, lowered suspension, Bilstein sports shocks, aftermarket capacitive-discharge ignition....and it made it through emissions testing w/o a problem. We called it the Yellow Peril .

yes but

mechanical fuel injection system

and

aftermarket capacitive-discharge ignition

so not a carb and old school points. and you still had to replace plugs more often than 100k miles.
and a lot of routine maintenance, (reading between the lines of the aftermarket parts installed)
and also i'm speaking to 50/60 by the late 70s a lot of things were becoming not old school and everyone was *****ing about those newfangled injection systems and electronic ignition systems.

Heated seats , lol . I have an example on the bench at work

2 elements , fan and control module. $2000 in parts from nissan lol
Oh the air filter for it is $180

I will take early fuel injection over a carb but todays cars are more complicated than need be.

The challenge now is finding rebuild kits that dont suck

What for? Carbs? Depends on the type of carb if thats what you are referring to.
