I've learned that on older cars. When you replace a part. Always keep the old one. For many reasons. Maybe value or originality. Maybe for reference. Maybe to rebuild. Or maybe it wasn't the problem to begin with.

I fell in a similar trap, putting a kit in an AFB, I matched up the used bowel gasket with the similar one in the kit, there were about 3 variations available. Someone in the past had used the wrong gasket, and the car ran fine as long as you didn't get into the secondaries, when it would fall on it's face.

[@indianaslim4971]

This was more along the line of experience and deductive reasoning than curiosity, once he pulled the hose off the carb and there was no change it moves to the next thing in line, the carb, after that it moves to gasket, then manifold, to newbie it may seem to be curiosity but to a mechanic it's just steps of the diagnostic procedure.

[@DoktorJeep]

Eventually you get to a point where the parts catalogs in the auto parts store don't go as far back as the year the car was built. And that's when it's time to always bring the old part in.

[@flinch622]

One of the funny things about old stuff is... you might want to stash away old catalogs - it varies company to company. Accel used to sell different ignition kits for example.... what was inside? Better have a catalog to look it up.

[@billywird]

Yes sir and as Uncle Tony pointed out carburetors are used in many various applications and it pays to keep all the old gaskets for comparison when installing a carburetor and even then if one doesn't pay attention one can install the wrong base gasket (as in this case) and inject a new problem and therefore blame the part they just installed.

As for that $80 carb, putting politics aside for a minute, keep in mind that China has a space station and a rover on Mars right now. They ARE capable of making high quality stuff...

[@MrToranaGuy]

China is capable of making high quality stuff. It all comes down to those who want something manufactured in China, how much they want to pay for their product, to what they will get.

[@Anthony-nw5zv]

And guess who's funding China? And yes they are capable of making quality products just like any other countries! The problem is there are too many people with the GET RICH QUICK mindset of LET'S HAVE CHINA PRODUCE IT mentality. Let's face it China produced that carburetor for $3.00 in a slave shop by workers making $.25 an hour for 12 hours per day. But we pay closer to $100.00 for the carburetor. Do I have to continue? I'm 66 and know what a hard day's work is!

[@MrZdvy]

@@MrToranaGuy Yeah, but in a lot of cases you don’t have a choice. If the made in China part is the only one available I will buy a Chinese made part. I ordered two relays for my C4 Corvette. I thought I was smart and ordered OEM ones. The correct AC/Delco box, but once opened up I noticed ‘Made in China’. Same thing with a Raybestos brake hose.

You are 100% correct. Worked for a company that made poly coated fabric. We got the fabric from China. And they could make cheap fabric or really good fabric. It's was whatever we wanted.

[@animoetprudentia2865]

Thanks for the reminder! I've been bit by the assumption bug several times (self inflicted). Most recently was my current Ford. Was chasing a gremlin for weeks. It ran but was inefficient, stumbly idle, plugs were lean, etc. I started firing the parts cannon at it, didn't improve. No vac leaks, all the grounds were addressed, driving me nuts. Driving home from the shop one night I let it warm up then pulled over and popped the hood to check my latest replacement part - the #8 plug wire was arching to the manifold - ?! Next day I ohm tested the wire and it failed, ALL of them failed, including the coil! I made the mistake of assuming the wires were good without testing them. Never again! It's those simple things that can be easily overlooked (at least for guys like me).

Put everything back the right way and now it works fine.

Give this a try. It worked for a guy who bought a mint little old ladies car. It drive fine in town but would sputter and smoke at 40+ mph. He pulled the plugs and shot a bunch of STP treatment in there. Let it sit for about a week. With the plugs out and rags handy to catch the mess, crank it over, blow out any fluids. Install plugs and see what happens. It loosened the rings in that car, might work for you too.

[@PaulThomas-qo9vy]

Good advice Tony! Don't assume anything! In my early career & training I learned: :Trust but verify" Which meant double-cheak everything, includung a trainee work! I ignored that last advice in an engine test facility. I asked him did you switch those oil line valves Back to the Run position? Yes, he said. I could have taken 6 steps around the engine stand to Verify, but I did not & we toasted the bearings in 3 min. of warmup. I took full responsibility, because it was my job to Verify! For cleaning the crankcase chemically, I would suggest a quart of Rislone Engine Treatment (extra detergents & gentle cleaners to run for 3K miles), plus 16 oz. of Marvel Mystery Oil. Both to be added at an oil & filter change, reduce the new oil by the 1.5 qts. the additives take up. Tony, what's your favorite cleaners for a cruddy crankcase?? Thanks for your advice & channel !

You know how we spell assume. And you are right about the whole field of auto repair as it takes a detective to dig down and find the root cause of the problem. And it takes a big person to admit that it is not always the "cheap Chinese" junk that is causing the problem. I recently replaced a starter on my pickup with a NAPA Remanufactured unit that had the sticker "a product of Mexico" and it had all of the specifications and checks made on that starter. I installed it and the amazement at listening to a like new starter. I had a time constraint here and went with the most efficient and cost effective method and this filled the bill. So far so good.

That’s what I have been trying to teach my son, don’t assume anything. I’ve been a mechanic for a long time, he’s still learning. Test, check, prove.

[@seabulls69]

Back in the old days (the 60s) when we suspected carbon or sludge on the rings (or lifters), we'd take either Marvel Mystery Oil or ATF and run it in the crankcase for a few hundred miles, drain the oil, change the filter, replace and run. Wasn't a cure all necessarily, but about as often as not, it would clean up exhaust or quiet noisy lifters. Cheap and easy.

[@Oldbmwr100rs]

Then run Shell Rotella fleet engine oil, it's made for heavy duty gas as well as diesel engines and has a lot of detergents. Change the oil filter before 1000 miles, because if the engine is really coked up, all that gunk will go to the filter. The oil is safe to run and has stronger anti wear additives, though I've heard they've been cutting those a bit. Best of all, the oil is usually cheaper by the gallon.

[@billywird]

Yes sir and in the old days of road draft tubes what one would do is to remove the road draft tube and pour a little gasoline on it (of course it is isolated from any flammable containers, duh!!!!) and lit it off to burn out the built up carbon in the tube in order to clean it out. Remember this; this was back when motor oils were no as good and were not changed at regular intervals and also the mindset that you never changed the oil (try working on one of those sludge bucket engines). The modern (actually came into beings in the late forties) PCV (positive crankcase ventilation) system has a big bearing on oil consumption and rings clogging, especially the oil rings that can get clogged up just as the old road draft tubes did) I did not realize this myself until a man that ran an automotive machine shop explained to me the design of the PCV system. Clears up a lot of mysteries about oil consumption.

[@Onewheelordeal]

We still do that in the now days, diesel or ATF in the oil and we mostly just let them idle with it with the occasional throttle flick to check progress

[@Broken_Yugo]

For a first pass you might try a milder approach of spinning on a fresh filter and topping off with ATF, then go practice high speed highway entrances for a couple hours, noting the smoke level. Sometimes a good wide open 0-80 or two is all it takes.

[@billywird]

Back in the day a friend of mine who a good basic mechanic would suggest adding a quart of transmission fluid to the gas tank(with each fill up mind you) and that would help lubricate the intake guides and also help with the carbon buildup. He also used the application of dripping transmission fluid into the carburetor for cleaning the carbon out of the engine. In fact I had completely forgot about that because it was back in the seventies.

[@minnesotatomcat]

I’ve had that happen with chainsaws many times. I’ll buy them for little or nothing cause they’re not running and normally somebody else has tried to get them running and failed so I gotta go through and figure out what’s supposed to be there and what’s not. A lot of those carb kits look very similar but they aren’t.

[@patricklynch1962]

I almost bought one of the Chinese BBD's to replace an original that seriously needed the throttle shaft rebushed, but instead I used a 1979 Holley 2280 in place of the 1968 BBD. The Holley has the same footprint as the BBD and was an easy rebuild from my parts stash. The only thing that wasn't a perfect match was the choke rod. I put an electric choke kit from Mike's Carburetor in place of my original and using both the thick and thin intake manifold gasket from my rebuild kit for everything to function correctly and it's been great ever since. But it looks like I could have bought the new BBD and kept going or even just swapped the throttle plate over to my original BBD.

[@benjamincresswell3713]

Just a couple of points: 1). Cars were around for a long time befor the pcv was introduced. Mopar's got it in 1963. 1967 the epa *(imposter branch of the gov.) made it a law. With today's oil, no pcv is no issue for crank case sludge. If you never run it long enough to warm it up, just change the oil. 2). That engine came w/ a Bbd 2bbl, where is it? It's about the simplest carb ever, no hidden wells or passages. Spray it out with today's carb cleaner using the provided straw and it'll be like new unless it's got over a million miles on it and the thrt shft bushings are gone. The trickiest part is setting the float level, as the needle and seat are in the inlet fitting, so you have to watch how far it screws in when you tighten it up. If you have all the parts, including the float pivot shaft bail, you can run it with the top off to see the float level. * The EPA is unconstitutional. Congress spota make the laws in this land, not EPAs. OK, gotta go. ben/ michigan

I just so happened to find a split over an inch long on a vacuum line, running from my power steering to the front of my intake plenum ( fuel injected Toyota 3RZ in my 2000 Tacoma 4x4 ), but it was hidden on the very bottom of the line. The only way I discovered it was by feeling underneath it with my fingers. I knew something wasn't right, because it was bogging like crazy. Damned thing runs like brand new now.......all over a bad vacuum line only 8" long. Lesson learned: don't rely only on visual inspections of vacuum lines. Run the entire length of them with your fingers to find hidden splits & cracks underneath that ya can't see. It's also the only way to detect if any vacuum line has become hard & brittle ( by squeezing the line ), which will start getting tiny cracks. Often times, it's the littlest, simplest things that can be the source of the problem. Now I know I don't need a valve adjustment, lol. Made my day.

I see there are different brands of Chinese carburetors out there. Please advise what brand was used in the video or what brands have been successfully used. Thank you.

B G Engine cleaner will take care of that. It is an engine cleaner for cleaning out Gack out of the tiny hydraulic passages inside modern combustion engines. That stuff is pretty acidic, and I don’t know what it would do to older gaskets. However it might be worth a shot...🤷🏼 But you were going to have to get in contact with somebody to get that stuff, it’s not as easily accessible to the public. However a lot of dealerships need it around Because people tend to think they can go 50,000mi without a oil change.😬

And by the way, The tire pressure on the left rear tire of bottle rocket is too high... The left side is kicking off the ground. Just lower the air pressure down enough on the left side (before dialing in the right rear shock.)

Hey Tony. How did you know the engine had blowby? How do you test for that?

Hey sir is the 600 street warrior on eBay a good carburetor ?

[@damarapoledna3636]

Lol, yesterday, I was thinking, check the gasket. Been there done that😁

See my comment and question on the first (70 satellite) video, about the use of single plane manifolds into 1970. Pretty sure they were 273 manifolds. My ‘71 318 D100 has the same manifold, My ‘68 Satellite with 48k miles came with the original dual plane manifold in the trunk. Without going to the garage to check, I’ll bet the dual plane has the holes for that gasket.

My teacher at school would rev the engine and pour small amounts of water down the carb to blow the crud out.

[@ChrisTheBmxGuy]

Im so used to the pcv rattling away it probably would have made me check it. Or I could have been oblivious lol. I know the one on my 85 d150 with the 318 is noisy as hell.

[@Wyowanderer]

Nicely done, UT.

Would a little Marvel Mystery oil in the crankcase clean out some of the gunk?

[@MikeLawson-cj4kt]

Now I know why the gasket that was supplied with my Street Demon is an open-dump gasket.
