not really seeing the TDC dimple, you might pull number one plug and put it to TDC, stick a dowel or the like down there and rock the engine to either side of TDC comparing the movement of the dowel to the mark on the pulley to verify where TDC is. It does seem to be a pretty complete original looking 1976 1200 engine though, so it's probably a 7.5 V-notch mark. |

It could be the original. Looks to be several original parts on there, more so than you often find on a 35 year old engine. |

I tried to look up that distributor model#. Couldn't find it with the list of Beetle distributors. I did find this thread that indicates it could be a T4 distributor?
http://www.thesamba.com/vw/forum/viewtopic.php?t=167649
I did a Google search and found a possible list of specs:
http://www.vwar.org/forum/index.php?topic=685.0
I can't speak for how accurate they are. The point gap seems very large (0.028").
The timing calls for TDC, which seems odd as well. _________________ AshMan40

No, that IS a mid-late 1970s type 1 distributor. You can find mention of it if you search the British vZi board. And it's on the chart of of distributors I compiled
http://members.trainorders.com/android/temp/CarbBaseFlangeNumbersA.doc
I wish I could remember where I leached this from, but it's in my reference file, I added the translations.

Hi,
How about a Brazil made Type 1 engine?
BH engine code, 1500cc
Is it 0 degrees as well?
Also timing light jumps or is not steady on the marker, an internal engine issue?
Thank you |

In case you didn't get the message throughout this thread... distributor model and timing marks on the crank pulley are a matched set. Since distributors and pulleys could have been swapped many times over the years, knowing how to time your particular engine will depend primarily on the distributor model you have installed.
So which model distributor DO you have installed?
Can you tell from your tach or by listening if the engine idle is pulsing which could be causing the mechanical advance to change at idle? Or is the idle steady and only the timing is changing? If it is just the timing, it is more likely a problem with the distributor. Maybe the points? Is your point gap/dwell set correctly? _________________ AshMan40

Thanks for the reply
I was trying to verify the correct mark corresponding with the engine code.
Sorry if I did not include some of the other details.
Yes the parts have been swapped over.
I bought a pulley since the older was not aligned.
So far the old 2 distributors I have are both 9 230 081 035. Both have same results.
Neither points or Compufire made any change too. Recently changed Plug wires too.
Today I marked the pulley TDC by feeling the Piston # 1.
I don't have a way to check the Dwell or RPM.
Update:
As you suspected, it looks to be the distributor is the issue, (advance mech).
Since I took off the Distributor to look at part # and then it placed back w/out the hose the timing light seems to be more steady. But then after putting the hose back the problem came back.
Am now in need of the correct distributor combination for the BH engine code.
Thanks |

I am new to this forum so I do not know how to start a new post.
I need help with ignition timing. I have a 1974 Supere beetle and I went to check the timing. I looked for the marks and found one mark facing the back and then one to the left on the inisde. |

Get a degree-d pulley. Best $40 I've ever spent. |

I have a different setup on my type 4 engine Pulley. on the pulley as you can see there are three notches.
on the pulley face
notch1 on the left 0 is stamped assuming TDC and
notch2 reads7 on the face assuming its 7Deg before TDC and the
3rd would have to be 30 before TDC.
To make sure you are at TDC on notch1. on my setup the rotor on the 009 distributor is facing the 7 O'clock position and also the mark on the rim of the distributor.
(on a type 1 beetle with a 009 Distributor i think it faces the 5 o'clock position)
when the pulley at TDC and the rotor is at 7 o'clock. If you look at #1 cylinder the intake and exhaust valves should be closed and on #2 cylinder exhaust should be rocking.
If you follow this proceeding you cant go wrong finding TDC. then you can do your cylinder #1 valve adjustments. then if your rotate the Pulley 180Deg then you can adjust your #2 valves and the same fro #3 and #4.
Once all adjustments are made advance the Pulley to 7Deg before TDC and do your static timing.
on my pulley opposite TDC, the pulley is marked 180..
Thats how i deal with my setup. Please feel free correct me if i am wrong.
and here are some Pictures of my ride before i installed a CB Quicktune EFI system and a T4 turbo.

Use a straw to find tdc of any piston. NEVER anything that can break. |

what i've learned so far today:
a) my engine (case...) is a '72
b) I have an SVDA pulley on a DVDA (intended) engine that came with a DVDA distributor held together with a crankshaft that has hand-written stuff on it
c) most importantly, big dimple is TDC. will check with straw method and re-time @ 3g RPM _________________ '71 SB - 08/1970

And pulling the distributor does not tell you anything either...
AFAIK only the 71 and later pulley's ( like in my picture posted earlier in this thread) have the "dimple" Some models were notched 5 ATDC for DVDA and others 7.5 BTDC for SVDA
This has always caused problems for owners or ill informed/non VW mechanics when an 009 or any other distributor besides the correct one was installed and the timing set to the factory marks on the pulley.
If yours has just notches and no dimple it is an earlier ( or possibly aftermarket) pulley and you can use a chart in one of the manuals ( like glutamodo posted part of one above) to find what marks on your pulley mean. BUT you still have to time it for the distributor you are using. |
OK...so my '67 bus has a 1973 "AH" code 1600 DP. Dizzy is a DVDA... Bosch 0 231 167 048. From what I've read, the timing should be 5º ATDC.
My pulley has the dimple (TDC) on the rear, and a "V" notch on the front side just to the right of TDC. Seems that "V" is for 7.5º BTDC. If that's correct, I need to remark my pulley with my own "V" 5º to the left of the dimple...right? |

Yes, it sounds like that's what you need to do. You might want to print out that degree wheel seen early in this thread.
However, make sure your DVDA retard diaphragm is functional - it is very common to find that they have gone bad.
No VW number on that distributor? If so, it's probably the same as the 0 231 167 049/113905205AJ. |
