new Empi 34 PICT 3 leaking at throttle shaft bushings

philvt101

Just got a 74 Beetle and the PO had just put a "brand new" Empi 34 PICT 3 on. It would only idle with the choke on. Found the base gasket not even on right, half way out. I replace the gasket but still had the same problem. Found the throttle shaft bushings leaking, especially on the choke side. So I found some replacement bushes on eBay but they're listed for the Solex, I'm hoping they'll work. But has anyone seen a brand new Empi have this problem before? I know it's supposed to be common on carbs with some age to them, but that just doesn't sound right to me. And the carb does look brand new...

Welcome to VW's

Rule # 1

Do NOT believe what the PO told you. Odds are high it was incorrect information, not always to deceive but often in simple lack of knowledge.

I have a new bocrap pict 34 that has same problem. sitting on shelf collecting dust. I think there is a balck gasket that goes on over throttle shaft between carb body and choke rod plate mine is missing.
I just rebuilt my old 30/31 and had not looked back

Any recommendations on a good replacement carb for a 74 Beetle 1600cc dual port, center mount?

Rule # 2

Don't buy anything new with the word EMPI on it. EMPI = JUNK.

I too have this carb if i could piggy back off this thread. i just bought a 034 SVDA distribuetor. what would be a good carb for this dist. i am having a stumble on acceleration problem and i think it is the EMPI carb ?

unfortunately the new carburetors that are produced are hit and miss when it comes to quality, more miss then hit. many of the mfgs use a nylon material for the bushings which simply do not hold up. I would suggest talking to Keith, username keifernet. he does rebushing and rebuilds on carbs and im sure he has some that are for sale or perhaps can correct the issues on your current carbs.

Honestly I don't know which distributor I've got. I just got the car and aren't really familiar with the different distributors available. It has no vacuum advance, only mechanical. I assume (probably not a good idea) that it is the factory distributor.
Also, I didn't buy the Empi, the PO did. I'm thinking of buying a Mofoco replacement, and I can't really get Keith to rebuild one for me as I don't have the original Solex.

Mikeys_Fasty · Posted: Wed May 11, 2011 5:20 pm Post subject:

ok. well like i said he may have one to sell already done, and will probably be cheaper then any of the repro's you'll snag. no vacuum advance means it's most likely an 009 (aftermarket). but if you were happy with it, no need to change it. be warned there are some strong opinions here on the use of the centrifugal advance(009) versus vacuum advance ( stock). both sides have valid arguments, but ultimately if you're happy with what you have, run it.

I haven't even been able to drive the car yet. The faulty carb came on it when I bought it, so I don't know how the distributor will work out, but I've seen quite a few mentions of the "009 bog".
Do you have any idea how long it might take to get a carb from Keith? When I checked out his page, he gave the impression that it might be quite a while. I guess I should just ask him, right?
Anyway, thanks for the input.

Mikeys_Fasty · Posted: Wed May 11, 2011 5:52 pm Post subject:

yeah, best to ask him directly. shhhh....don't use "009" and "bog" together.....you may stirr the beast.lol

if it appears keith can't help you, the next best source would be john at aircooled.net. but steer clear of the bocar, empi, bristol, "nonames". mofoco brand I've heard mixed reviews on, haven't had one from them myself so I can't say one way or the other.

I talked to Paul,(email), today about MoFoCo's carbs. He says they are Chinese knock-offs. Even though they set them up for you on a running test motor, I still don't want anything "Made in China" on my bug if I can help it. Not talking

@Roy
I didn't see any options on the Mofoco site. Just a single version of the 34 Pict 3 with no indication of who manufactured it. But if you do indeed rebuild/bebush the original German carbs, what is the price difference?

The Beast ?
More like avengeing Angel sound's better ? LMAO
Your carb is flooding over !
Most likely reason's for flooding are .
1) Excessive fuel pump pressure .
2) badd inlett valve .
3) Wrong washer under the inlett valve .
4) Badd float .
5 ) Some other reason that is beyond my expertise like cousin Jethro had it apart ?
As to EMPI
again ?
1-800-satanic beast - Empire > Translation 1-800- 666- EMPI is the empi technical support phone number .
So you need to call Satan's Empire up to get help with your Chinneeese aftermarket part ?
Ahhhh ?
Hmmm as in good luck with that ? Twisted Evil

LMAO
Hey obviously Im not smart enough to make this bleep up ?
The number I gave you here is there number for there technical support .
But yeah Empi part's usually work chances are cousin Jethro has had it apart and failed to install the proper thickness washer under the fuel inlett valve on the carb .
Or fuel pump pressure is excessive .
A good question to ask of the Empi Tech is what thickness washer goe's under there inlett valve on this carb and what the maximum fuel pump pressure is for there carb's .
Stock solex / Bocar pump's put out 5-7 PSI .
Webbers need 2-3 PSI .
gas actually comming out of the throttle plate bushing wreak's and scream's that this is an inlett valve or float problem ?

God points Sean the truth is what it is even with a little laugh.

With the same carb that I sold at my parts house I always supplied a plastic filter for obvious reasons.

One guy comes back to me complaining it would not idle after installation.

"Okay" I says, bring the car by so I can take a quick look see.

He comes by and it won't idle as he said. His wife is standing there with daggers coming from her eyes and she is p***** because of the money spent.

I back off the idle jet and the car idles okay, screw in the jet and it dies. Remove the idle jet and there is a tiny piece of what could be called a piece of straw i the small hole. I show it the guy and ask "what is this supposed to be as they do not install this object at the factory of origin".
His mouth drops open and his wife has a funny look on her face.

I ask him what happened to the filter I gave with the carb. He says that the old filter looked okay so he reinstalled it.

There is bound to one in every bunch (customers that is).

Dave,
You misunderstood. I never mentioned the quality of their parts, you did. I just avoid supporting China's export business in general. I will take that extra time to research where my parts are coming from. I bought my heads from Mofoco because they are made in the USA. They weren't cheap, but the quality is superb and the $$ supports a couple of families here, not in China.
Phil, sorry to step on your thread. I hope you got your problem solved.
