What the muck is this? Ewwww yuck continued.

It's NAPA "Mac's 6402 Carburetor Cleaner with dipping basket" $49.95. If youa re telling me that I over paid, I'm taking it back next time I go.

 

[Nunyas]

Yeah, we believe you paid too much. If I recall correctly, the Gunk Carb Cleaner with dipping basket I purchased was in the 20 to 30 dollar range. Indeed, Gunk's website seems to indicate it's ~$27/gallon. AND it's "environmentally responsible" /bcforum/images/%%GRAEMLIN_URL%%/wink.gif I didn't even notice that part with I bought it.

I just paid $19.99 for a gallon with backet of Berryman's at Autozone, so I think you are being over charged.

 

[wdp]

I mean BUCKET not backet. This stupid computer is always misspelling words. I mean with basket!

My thoughts exactly -- '69 B, all emissions gear intact & functioning, could not ask for it to run better!

Am I the only one who peed myself laughing?

 

[eschneider]

I see alot of the soldered poppet valves.... why not just replace with new solid butterflies, they are $15.00 or less a piece, that's what I do on all my carb rebuilds.

One answer to "why" is that the old butterflies usually fit when you re-install them.....

Sounds like you haven't had a problem with new ones though - mind if I ask where you get 'em?

No, Eric.

But I deleted my response.

There's only one reliable supplier left for SU parts AFAIK: Curto. The stuff from the white box suppliers is usually ill-fitting ballast material.

I have the EGR valves in my HIFs along with the full complement of EGR equipment the car came with in 72, pump, gulp valve and all, and I couldn't ask for it to run any better. Lots of pep, no bucking, jerking and will run 70 MPH all day long and I get great gas mileage. I still can't see why everyone wants to, (strip), the engine of the original equipment when it's going to be used as a street machine. Amazing! Absolutely amazing. Sorry for running on.

EGR valves? Not too sure about that on an SU equipped B. An EGR valve would need to be plumbed into the exhaust manifold somewhere. As I recall, the smog plumbing on a CBB only injects air or collects vapor. RBBs had EGR valves.

Performance gains notwithstanding, I can see two reasons why people remove this stuff. It adds weight and it is something else to break.

Doc-

Try these folks:

They bought the SU tooling; they're likely Curto's source:
"The S.U Carburetter Company Ltd is now a wholly owned subsidiary of BURLEN FUEL SYSTEMS LTD."

I checked on my way home last night. A gallon can of Berrymans Carb & Parts Cleaner at AutoZone was $20. It's on the bottom of the chemical shelves next to other products in gallon cans.

Advance Auto carries the Gunk product and I posted their "partsamerica.com" link to it above. I don't know why they bother putting it on partsamerica... I don't think they can ship it! Anyway, Gunk is about $18/gallon in the dip can.

NAPA's product is probably great but I doubt it's worth 2-1/2 times what the other products cost. If you haven't opened it I'd take it back and head to Advance or AutoZone.

As mentioned, take all the rubber and plastic bits of the carbs before soaking the bodies.

Rob,
I don't think anyone is questioning how well your car runs. The "funny" part about your quote is the '69 B should have little to no emissions gear. (At least compared to the 76 and newer). It's the smog pump (looks like an extra alternator) that most people remove.

For example, my '76 B (for off road purposes only /bcforum/images/%%GRAEMLIN_URL%%/wink.gif ) has been modified to be set up more like your '69 then when it came off the showroom floor.

Although the next time i am in NC, i would love to drive your car!! /bcforum/images/%%GRAEMLIN_URL%%/smile.gif

I got my parts for the HS6 rebuild from these guys: https://www.aptfast.com

I ordered my parts via phone, and the gent I spoke with was very knowledgeable in what I was looking for.

Let's see,
Poppets on throttle valves: check
Crankcase ventilation: check
Gulp valve: check
Air pump: check

The only things that would not have been on a '69 that came on later SU-equipped cars are the temperature-compensated jets in HIF carbs and evaporative emissions systems (which even the "rip that crap off" crowd generally acknowledges as having no effect on performance). My car is certainly one that would be considered "emissions-strangled" -- I've even been lectured on why I should "rip that crap off." My response has always been, "You haven't driven it."

So no, I see nothing funny about my statement.

ZS-equipped cars are a somewhat different matter, but their Achilles heel is not the emissions gear but rather that horribly inefficient intake/exhaust manifold. In addition to the above, they get EGR (not necessarily bad -- allows higher compression ratios -- more power -- with less detonation), a catalytic converter (not bad in itself, but perhaps a sub-optimal implementation), and some minor things like intake air preheat (that flap in the air cleaner). They also get the cam advanced a few degrees, probably to compensate for the horrible manifold, which boosts mid-range power but at the expense of top end.

And if you're in the Raleigh area, I'm on theList....

Cheers!

No, I thought that was subtle, tasteful humor? '69 was kind of pre-egr, wasn't it.......?

Just wanted to clarify that I wasn't snickering at the notion of your car running well. Apologies if I offended....

*edit* OK, just saw your post.

Joke's on me. I had no idea a '69 had poppets, smog pump, gulp valve......

I'm officially putting my tail between my legs now.

 

[vping]

Just got back from NAPA with my $54.08 in hand. As I looked around I noticed that some of their stuff was high priced. I might not use them again and will try autozone for the carb cleaner. I had a few cans and sprayed down the extra pair of carbs. These are looking like the ones I'll use. I really need to get that other gastank out to determine if it is useable soi I can start this baby.

 

[Nunyas]

Ah, but personally, I think I have more confidence in Napa parts being of higher quality than anything I get from VautoZone

That's funny, I got your joke because i was as ignorant to the '69 set up as you were.

Mr. Edwards, thanks for setting us straight /bcforum/images/%%GRAEMLIN_URL%%/smile.gif

look at what happened to us when we ASSUMED we knew what we were talking about

I build about 50 sets of SUs a year along with all the other MG rebuilding I do, I get all my carb parts from Joe Curto, that's my buddy, I put early model butterflies on everything, as most old butterflies get a wear pattern right beside the shaft on the linkage side and can cause binding if you re-use them, HS2s are the worst about this, HIF4s are the best as for not wearing the shaft and butterfly.

Here's a picture of a MGB HIF4 assembly I did for a customer not too long ago.

[dklawson]

Hap, I know this question comes up frequently in threads about dressing up SUs, but... what did you do to get that finish on the suction chambers and what do you put on them to keep them looking that nice? That's a great looking set of carbs.
