Posted: Fri Mar 26, 2010 10:34 pm Post subject: Best carb and distributor combo for a stock 1600SP? |
|
|
I've been doing a lot of searching but I still can't make a clear decision.
My current setup is a 30 PICT-3 and a 009. I can't get it to run right at idle. Driving seems ok but it definafely has the flat spot I've been reading about. I really like the idea of a SVDA distributor, I'm looking at the complete Pertronics one (any good?). What is a good match for a stock or stock style carb? I've read that I can't run my -3 with a svda, so I think I don't want to waste my time with it.
Can you run a 30 pict-1 with svda? Seems like my kind of tuneable basic carb.
Or am I stuck with a 34 pict-3? Will it be too much for a single port?
Are any of the new carbs listed on the Cip1 site any good or what are my other options?
The engine is in good shape, no smoke or leaks, valves are adjusted and it cruises nice so far.
Any help would be great! I just want to drive it so bad and not waste my time with my current setup. I also plan on ordering a scat degree pulley.
One last question what's a good plug I should use?
Thanks in advance! |

Keep the 30 pict 3 and look for a 113-905-205T from a 69-70 Beetle.
You should be able to make it run without flat spot with the 009, the 34 pict 3 is the troublesome one with the 009. Make sure the vac port is capped. I would still look for a 205 even if you get it to run better with the 009.
The 34 pict 3 won't fit your singleport manifold without an adapter. _________________ Pres. Rivercity VW Club www.rcvwclub.org

Now that I know some options, everthing in the link above would apply to a 30 pict-3? What jet size would I have to increase to?
Also reading about the 205 distributor.
Thanks for the help so far, keep it coming! |

I've had these on for about 6 months with a german 009 and they are worlds better than stock.Increased power and pulls to 5000 rpm where the stock solex was done about 4200 I opened them up when I got them and had to set the floats but they were clean inside and installed easy.

link is dead man...what are "these"?
stock carb will work...it will underpower the engine a bit but in some peoples opinion that makes it more relable because the engine is never pushed anywhere near its full potential.... I have a 1600dp and dual baby dell frd's and an 009....works pretty good for me. However the frd's would run smoother on a sp engine due to the fact that they are single barrel carbs like kads or ict's....which would be my advice for you to use.... there are many distributers to choose from...vacum or mechanical advance has to do with your carb choice.. _________________ _________________________________________

Best carb/distributor combo for a 1600 IMHO, Kadrons and an SVDA. You'll have to drill a carb to get port vacuum. Although many moons ago I ran my Kads with an 009 with no problems - no flat spots. |

i'll have to agree...any dual 1bbls & a SVDA. but i'll just throw out the other "best option":
single zenith & o1o or o19.
the title does say best "carb", as in single. _________________ 88 Van WBX, A/T - 93 Multivan 5cyl 5M/T - 13 JSW TDI 6M/T - 2012 Touareg TDI Sport

Ok, I'll say something since no one has covered it yet...
To get the 34 pict 3 to run right with a 009 distributor you need to have the carb jetted right...
I had the same problem like many do when using the 34 pict 3 with an 009.
If you know of a reputable VW guy, he can shed some light on this, why, it is how you generally solve the problem.. It has to do with the mains and plump jet sizes in the carb.. That is the trick, a little more fuel on the pump circuit and a little increase in the mains will clean it up, no more flat spot.
I know I make it out like it is easy to do, but to be honest I had to have my local VW Wizard do mine up, and that is with no drilling to butter fly as some say needs to be done...
So, just call around or ask your friends who is the VW Wizard Guy in your area who knows how to fix the carb with the right jets or a drill, which can do it, you can solve your problem with out swapping anything out. That is of course your distributor is in good working order, remember to lube the shaft under the rotor button at every oil change, just a few drops on the camel hair is all you need... People have been recommending Marvel Mystery Oil for years for this application...
Hope this helps, will keep from having to buy other components that really are just obsorbing your wallet.... RB |

You're right, hard to argue against the Zenith! (in single or duals) |

I netted 31.1 mpg in my old bus doing 65mph @ 4000rpm with its singleport 1600. Wonder what that motor would have done in a bug!
Ran a 30 pict with an 034 distributor timed at 32 btdc total centrifugal advance ( mid 40's with vac line attatched), 115 main jet.
I'm at 4400 ft elevation, so adjust for your car accrdingly, as well as for any differences between motors.
It's a good "maintenance free" setup if you don't care about max power and all that stuff IMHO.
I guess the short story is, an 034 works great with the 30 PICT. _________________ Eric Allred

I originally had a 1500SP in my rail with a 34PICT3 and 009 distributor with the Pertronix electronic module in it. I could not get the carb adjusted right to save my life. It wouldn't idle correctly and had a bad flat spot just off idle. I had to keep the rpms up to keep it running. Had a 1600dp installed with a 34PICT 3 and a SVDA distributor and Pertronix electronic module and it's ran fine since day one. Not sure of the model number of the distributor (it was a used one). |

Ideally I'd like to stick with a stockish style setup for now to buy me some tine to look into a really nice dual carb setup. Right now my focus is reliability, mileage and parts availability.
Ideas I like but still have questions:
adapting a 34 pict-3 to my intake to use a svda, what size jets would I need to run it on a SP?
Filling the hole in the throttle plate on my 30 pict-3 to use my 009, again what size jets would I need?
Using a 205 distributor, I'll have to read more about them, I still don't understand them fully.
Other options are a 30 pict-1 with a mech advance distributor.
Keep it coming. Learning alot and I want to drive this car without it stalling everytime I clutch in!
Thanks so far |

just got my vintage EMPI manifold (some chrome for the engine. yeah, baby!) with preheat that'll bolt to a treuhaft header...for my bay bus
to answer a few of your questions A-Wall: if i was in your shoes i'd go for the 30PICT1 w/ an appropriate full vac (SVA) dist such as a 205T.
stay away from aftermarket stuff--like the pertronics dist & new carb. there are people out there that may disagree...but...
if you're going to drop some coin you should know that properly rebuilt or even gently used & refurbed to the best of your ability OG stuff is always better.
depending on what road you go down you can shoot me PMs about jetting for your combo.
NGK BP6HS are hands down the best plugs for stock(ish) applications. _________________ 88 Van WBX, A/T - 93 Multivan 5cyl 5M/T - 13 JSW TDI 6M/T - 2012 Touareg TDI Sport |

thanks you! for answering my questions.
i took apart my carb, and it's rebuilt and in very good shape, i tried the filling the hole in the throttle plate thing, and the car runs the same but holds an idle it the air bypass screw is turned all the way out pretty much. I don't like it and i'm changing it back.
i also found out that my main jet is a 127.5, kinda big isn't it?
since this carb is in such good shape, i feel once it's jetted right, this 205t distributor is the key. i just have to find one in good working order.
the plugs i ended up running are the B6HS, i couldn't find the projected ones on the shelf locally. |

which carb are you using the PICT2?
before you remove the pop rivet try just pulling out the center of it.
what you really want to do is reduce the size of the hole not fill it completely.
you'll have to keep your jetting a touch fat for the oo9.
what are your air & idle sizes? 75/55?
what elevation do you live & drive at? _________________ 88 Van WBX, A/T - 93 Multivan 5cyl 5M/T - 13 JSW TDI 6M/T - 2012 Touareg TDI Sport |

when you richen jetting to elminate the 34/009 flat spot, your MPG takes a big hit. That's why the 009 is such a poor match to the 34 series carbs. _________________ It's just advice, do whatever you want with it!
